How to troubleshoot and fix a golf cart charger

What do you want in a golf cart charger? Golf cart batteries are lead-acid batteries that operate at 36 or 48 volts. Like all lead-acid batteries, they must be charged at a specific voltage and amperage levels. They cannot be fast charged — a full charge requires 14 to 16 hours.

You also want a “smart” charger that controls the amount of current that is supplied to the battery, and a timing mechanism that switches between a series of voltage and current levels.

For a cart that’s used for running down to the mailbox, or out to the barn once or twice a day, or any moderate or infrequent use, 12-15 amps is usually sufficient for charger output. For running around the ranch or warehouse all day, or 18 holes of golf, the 20 to 25 amp units would be appropriate.

How to troubleshoot and fix a golf cart charger

Most golf carts are equipped with 6-volt lead-acid batteries, which are small versions of car batteries. However, batteries in golf carts often don’t last as long as they could because of neglect and improper storage. You can do several things to make a golf cart battery last longer, including reconditioning the batteries. You also can reduce problems by making sure all electrical devices on the cart are turned off when it is not in use.

Step 1

Use a charger designed for lead-acid batteries that has the capability of automatically switching to low (trickle) charge when the battery is fully charged. A low-power 6-volt solar battery charger also works well. Charge the battery whenever it may be depleted or won’t be used for several days or weeks.

Step 2

Remove a golf cart battery to charge it, using a crescent wrench to loosen the battery cables. Use a mixture of water and baking soda to clean any deposits around the battery terminals and cables. If it is not a sealed battery, remove the cell caps and top them off with distilled water. Do not use tap water because it contains chemicals that will damage the battery and shorten its life. Turn the charger off while you connect the power leads (make sure positive is connected to positive and negative to negative). Set the charger according to manufacturer’s instructions and turn it on. When charging is complete, turn the charger off, remove the battery, and reinstall it in the golf cart unless you are going to store it.

Step 3

Store a golf cart battery properly. Although lead-acid batteries hold a charge well, they will drain if they sit on a shelf long enough, resulting in a deep discharge. You can leave the golf cart battery connected to a regular charger set on trickle charge or use a small solar-power charger. If using a trickle charger isn’t feasible, charge the battery every couple of weeks.

Recondition lead-acid golf cart batteries to extend their useful life. Even with proper maintenance, the lead plates in a golf cart battery may become sulfated. This is relatively easy to remedy. Remove the battery as you would to charge it. Before charging, drain the fluid from the battery and replace it with a mixture of 12 percent to 15 percent magnesium sulfate (Epsom salts) and distilled water. Then recharge the battery. It should resume normal function, though you may have to recharge it a couple of times to bring it back to full storage capacity. Note that because the lead pates can suffer damage from the sulfation, reconditioning a battery won’t work more than a few times.

How to Troubleshoot Your Golf Cart Battery Charger

If you own an electric golf cart, you are undoubtedly familiar with charging the batteries. If your batteries get too low, you could be stranded. To avoid this, you have to ensure that your battery charger is working correctly.

If your battery charger ever fails, you should have some sense of where the problem might lie and how to mitigate it. You can’t address every problem with a simple DIY repair, but a sound diagnosis can save hours of frustration. In many cases, the solution is simple, and you’ll be able to handle it with minimal expense. In cases requiring a professional touch, at least the diagnosis will be definite. Read on for a list of symptoms and solutions for your battery charger.

Your Charger Won’t Turn On

If the charger doesn’t turn on, it may still be functional. Here are a few things to check first:

Make Sure the Batteries have Some Charge

In the scenario that it doesn’t turn on, it might mean you waited too long to recharge them, and now the charge that they currently carry is too low for the charger to detect them. When your charger can’t tell that your batteries are hooked up, it often won’t even turn on. A base charge of 25-30 volts is usually sufficient to wake up your charger and begin charging.

To get around this problem, specific chargers offer modes that keep your batteries charged even when you’re not using them. This is useful if you go out of town and you want to avoid coming home to dead batteries. However, if you’re stuck at no charge, a small, manual charger should provide each battery with enough juice to activate your regular charger.

Check Your Connections

If your batteries aren’t hooked up correctly, or the connections between them are weak or frayed, this can quickly lead to a loss of power and cause your charger to fail. Make sure you check each battery terminal for corrosion; any buildup will impede the flow of electricity, and could likewise cause problems.

Battery vs. Charger

Generally, if you plug in your charger, and nothing happens, this is most likely a problem with your batteries or connections. To know whether your batteries need replacement or recharging, you should own a voltage tester. By testing your batteries you will get a strong indication of whether they are still working and need a charge, or if they need replacement.

If you find that your golf cart won’t go very far on a full charge, then you probably need new batteries. Test them to make sure that the power on them is low; if indeed it is, then you need new batteries.

Battery Charger Problems

Charger Runs Too Long or Not Long Enough

If you plug in your charger and it charges for too long or not long enough, then you may have a problem with the device’s computer. A failure in the “brain” of your charger can result in it not knowing when to stop charging. A quick tutorial on how to replace this component might save you some cash, but you may need to purchase a new one.

Clicking Sound

If the charger makes a clicking sound when you plug it in and then does nothing, this is a strong indication that the charger knows it’s time to charge but is failing for some reason. You should have a professional examine it. When replacing any component of your charger, check your warranty, if you have one.

Golf Cart Issues

If you own a 48-volt Club Car, sometimes your golf cart itself can get in the way of a proper charge. If your batteries are carrying a minimal load, and your charger will still not charge them, it may be because your golf cart’s onboard computer is confused about how much charge they are currently carrying. Only the club car can monitor the charge of your batteries, but it bears mention because these computers can fail, thus requiring a replacement.

If the Club Car’s computer is working correctly, the relay should make a “click” sound when you plug in your charger. If it does not, then you could easily have a blown fuse. If you check the fuse and it is okay, then you could also have a damaged relay, although this is rare.

Troubleshooting different types of deep cycle batteries can be a daunting task for those without experience. When in doubt, put your trust in Powertron Battery Co. We look forward to putting nearly 60 years of experience to work for you.

Whether you own an electric or gas golf cart, it’s going to face some technical issues down the road. With frequent use, problems with the battery, tires, and other parts are extremely common.

When the time comes to dealing with some of these complications, you have the option to hire professional help. But if the problem you’re facing is simple to fix, and you’re willing to take the DIY approach, then you can save some money and time by following the simple repair tips below.

Batteries

To reduce the risk of battery malfunctions, do general maintenance on a regular basis by making sure your batteries are properly watered and free of corrosion.

The most obvious sign of an issue with the batteries is when your golf cart doesn’t start. The first thing to do in this case is to fully charge your battery. If after doing this, your cart still doesn’t start, then your battery is probably dead.

Before changing the battery, take a look at the terminal cables to see if they’re the root cause of the problem by cleaning them and making sure they look alright. If that doesn’t solve it, then proceed to install a new battery by disengaging the terminal cables and placing a fresh one in its place.

Tire pressure

Do your tires look saggy? Or overinflated?

Your tires should be fully inflated at the right pressure. Otherwise, you’ll have tires that either suffer from low traction or low efficiency.

To find the right pressure, check the air pressure rating in each tire’s rim. Then, with an air pump, inflate each tire to the appropriate pressure.

Flat tire

If a flat tire refuses to inflate due to a leak, replace it. Begin by raising your car with car jack. Then, unscrew the lug nuts, and remove the tire and wheel rim. Then, replace the old tire with a new one.

Bad Solenoid

A solenoid is a cylindrical coil of wire responsible for carrying electric current to the motor. It’s not uncommon for this part to stop working because it has to work constantly when you use your golf cart.

Have you heard a clicking sound when accelerating your car? That’s the solenoid.

When the solenoid isn’t working properly, you might stop hearing the clicking sound, and your cart might have intermittent issues starting. If your battery is working well and your car is having trouble starting, it might be time for a solenoid replacement.

Properly maintaining your golf cart will help to ensure it’s in prime condition for years to come.

There are many different systems to consider when troubleshooting your electric golf cart motor. The motor is the last in a series of components that could fail. After determining that the cart’s batteries and charger are working properly, you can reset the motor to see if it runs. You must replace the motor if it has burnt out.

Check Batteries

Test each battery with a voltmeter to see if it is depleted. With some models, the cart draws a small amount of electricity even when it’s not running. Over several months, this can completely discharge the battery. Modern chargers must detect a minimum voltage to initiate the recharge sequence. Leaving the cart unplugged for a long time can cause the battery voltage to fall below this level.

Batteries will also lose their capacity with age. Check the level of water and electrolytes. There should be enough water to cover the conductive plates, but not enough to fill the battery all the way to the cap. The batteries contain acid, so wear protective gear and avoid spills. Clean corrosion from the terminals by brushing with a solution of baking soda and water. Check the cables for broken or frayed wires. Extend the life of the batteries by recharging them fully after every use.

Some carts allow you to adjust the torque strapping the batteries in place; keep this within the manufacturer’s specifications to prevent vibration. Vibrations during movement can cause internal damage to batteries.

Listen for Solenoid

The solenoid should make a clicking sound when you turn the key to start the golf cart. If the solenoid doesn’t work and the battery is full, replace it.

Inspect Charger

Test the outlet the charger is plugged into and examine the charger connections. Again, check for signs of corrosion or frayed wires. Also, a power surge could cause the circuit breaker to trip or the diodes inside the charger to fail. If you suspect a power surge has occurred, check these components.

Inspect Potentiometer

The potentiometer is a small switch that controls the speed of the golf cart. Make sure that the potentiometer is not cracked and that the connections are secure.

Reset Motor

Use a screwdriver to locate and expose the motor. It may have a small red reset button near the main power supply. Press this button and reassemble your cart. Connect the golf cart to the charger unit and recharge the batteries. Attempt to operate the golf cart again. You may also be able to test the motor in isolation from the circuit using a charged battery. If the motor does not spin, it might be burnt-out.

Motor burn-out can result from excessive resistance from weight, grade, or poor traction. Uninstall the motor and inspect it for damaged bearings, field coils, or worn brushes. These parts can be replaced with right tools and some patience. Damage to the armature or motor housing generally cannot be repaired so easily and will require the whole motor assembly to be replaced.

You should be all set thanks to this guide on troubleshooting your electric golf cart motor. Time to hit the green!

Are you fond of playing golf? If you are, then you must also use the golf cart to get around the course easily. No one wants to walk too far with all the heavy golf equipment at hand.

Golf carts make it easy for golfers to navigate their way all over the course. But imagine if the battery of your golf cart goes flat while you are in the middle of a game?

Isn’t that just inconvenient? If you think the battery is dead, don’t throw it away just yet. We’ll teach you how to recondition golf cart batteries in no time, so you don’t have to spend money buying a new one.

Let’s Revive Dead Golf Cart Batteries

The difference between the batteries of golf cars and that of other vehicles is that they do not need a lot of power. It just needs enough to work on smooth roads but for a longer time.

The batteries used in the golf carts are mostly 6-volt lead batteries or 12-volt lead batteries. The life of these batteries is primarily low as they are mostly ignored. The improper storage and the way they are used also contribute to the battery’s short life.

Most often these batteries, when not functioning properly, are thrown away. The better way to deal with them is to rejuvenate golf cart batteries as it will save a lot of costs and is also an environmentally friendly way to live.

There are simple steps in which the golf cart batteries are rebuilt. These steps should be followed in the same sequence to gain the right amount of revived battery power.

Here are the steps to follow :

Step 1: The battery should be removed. Most of the cart batteries are placed under the front seat, and you will have to lift the seat up to remove the battery. This could be different for some other cart models who have a hinged seat which can be lifted straight to take the battery out.

Step 2: Start with cleaning the battery. Clean all the corrosion off the battery. First, put on the gloves and the goggles and mix two tablespoons of baking soda into water. Stir the mixture well. Now, use a paintbrush and dip it in the mix. Use this brush and solution to paint all over the battery where there are signs of corrosion. Particular attention should be given to the terminals of the battery. Be careful as the mixture will generate bubble or fizz where the solution and the acid from the battery will come in contact.

Step 3: Now, use the same brush to wash it with fresh water and brush it all around the battery. Go and clean the whole battery and wash away the entire corrosion from the battery.

Step 4: The process to revive golf cart batteries advances with the inspection of the battery for any cracks or any defects. It is advised to replace the battery if there are signs of acid leaking into the battery compartment.

Step 5: You now use a screwdriver and other tools for this step. Remove the cap that covers the battery cells. This could need a little pressure and push. To recondition the battery, the cap should be opened totally so that the distilled water can be filled in them. Fill the cell carefully with the help of a funnel.

Step 6: Use the three-phase charger to charge the battery. The battery should be charged for about 12 hours. Make sure that you are using the right volt if it needs automatic setting set the voltage at 2.3 and 2.35-volt charge. Connect to charge. Carefully connect the positive wire to the positive pole on the battery and the negative charge to the negative pole on the battery. Plug it in and then switch it on for charging after it is safely connected to the battery.

Step 7: Leave it for the night. Check the charging level in the morning. When the battery charges show that the battery has been charged fully. Check the cells and check if there are any cells where the battery plates are open to the air, and the water levels are low, refill these cells to cover the plates with enough water. Replace the caps on the cell and cover the battery again. If the outcome is that the battery is not fully charged and you must have to take an additional step.

Step 8: The battery should be tipped on one of the edges. This is done let approximately half of the acid from the battery to drop out of from each cell. Make sure safety precautions are carefully followed, and the acid is collected in a container. Make use of the paint brush here which is dipped in the solution of soda as mentioned earlier. No drop of water should go inside the cells.

Step 9: Now take about 8 ounces of Epsom salts and mix it well with 2 quarts of warm water. Make sure that it is stirred and dissolved completely. The cells should be filled with this solution until the cells are full and then cover them. (You can learn more about battery recondition with Epsom salt).

Step 10
: After these steps, charge the battery again for about a night. The salt used will remove any deposit on the plates of the battery which is the reason why the battery did not fully charge. After this step, the battery is ready to be used, and your golf cart can be up and running again.

Here’s the Next Step

You will be excited to play a round of golf again when your golf cart is running with the help of this process. The steps on how to recondition a golf cart battery are easy.

Just familiarize yourself with the steps we have mentioned above. Be sure to use gloves and goggle when performing the process so you will be protected from any harmful chemicals.

If you have a golf cart you will eventually need to troubleshoot the golf cart motor. This is an easy thing to do quickly. Remember, it is a gas-powered engine that is not much different than your lawn mower or car. You are going to go through some of the same steps to troubleshoot the motor.

Minor Problems

Does the motor turn over when you try to start it? If not, the first place you need to look is the battery cables. Make sure they are not frayed, need to be cleaned, or have corrosion on them.

Also make sure they are tightly connected. A loose connection can cause there to not be enough current to operate starter. Make sure you check this on a regular basis.

Engine

Check the distributor cap for cracks. Take it off and check for moisture. If you see any wetness, leave it to dry and then try to start it again. Check the spark plug wires to see that they are free from breaks, cracks, and disconnects. If they are frayed or brittle, you will need to replace them. Take your spark plugs out and make sure the gap is set correctly. You can find out the gap setting from your auto parts store or on the spark plug box if you have one. While you have them out be sure they are not blackened or burnt. If they are, you will need to replace them.

Check the air filter element to make sure it is not clogged with dust. Gently hit it against your hand to rid it of all the dirt that is in it. If it gets too dirty it can cause your engine to not get enough air and stall out. Check the oil level and make sure you have enough and that the color is light and not black. If the oil is blackened or dark, you need to change it. Get a new oil filter and enough oil to refill the engine. Drain the oil through the plug on the oil pan underneath. Change the filter out and refill it with clean oil.

Gas Lines

You are also going to want to check all the fuel lines coming from the gas tank and going into the engine. Check for leaks, brittleness, and holes. If these lines have issues, you will need to replace them. This is easy to do as they are held on with clamps. Just get the new lines, unscrew the clamps, remove the old lines, and install the new ones reusing the clamps from before.

Fuel Filter

If your engine has a fuel filter you will want to change it regularly to keep the fuel system running smoothly. If you do all these steps on a regular basis, your golf cart should last you a long time. Regular maintenance is the key to making equipment last.
