Why Does My Golf Cart Charger Not Shut Off?
A golf cart charger will not shut off due to a faulty battery, faulty charger, damage to the power cable, or insufficient water levels in the battery.
- Bad Battery: In general, charging problems with batteries occurs when the battery is no longer in the space of fixing. It’s time to change it.
- Faulty Charger: You can check if the charger is alright by testing it to other cars. Maybe your friends who also have a golf cart can give you a chance to use your charger to charge their cart. See if the situation becomes the same; otherwise, maybe it is alright.
- Damaged Power Cable: Power supply plays a significant role in charging any device. This is why the power cable needs to be perfect to charge your cart correctly.
- Low Battery Water Levels: If your batteries’ water level is lower than it needs to be, things like this can happen.
- Bad Terminal: Make sure the terminals are in working order.
Before declaring your battery, the culprit, make sure to taste it. You can taste the battery using a voltmeter and hydrometer. It will cost much less than the repair or purchasing price of your cart’s batteries.
Why Club Car Battery Charger Won’t Stop Charging
The golf cart’s charging problems are not something new. Almost all the golf cart users face the charging issues at some point. So first, I want to tell you that the causes will not lead you to replace the entire cart.
Here are some general reasons behind your issue:
- Most of the time, charging problems of golf carts comes from a damaged charger. I cannot confirm it, but you should taste it before throwing it.
- Maybe the charger fails to provide your golf cart with enough power supply, which is why somehow your charger is failing to act appropriately, and it’s not shutting off. Plugin your charger somewhere else and see if it is still working abnormally.

If the charger is charging your cart’s batteries more than it needs to be, then the further voltages may damage the batteries. I recommend that solve the problem as soon as possible.
Follow the different troubleshooting mentioned below and see if any of it works:
- The timer board in the charger does the job to shut the charger off after 16 hours, even if the batteries are not fully charged. Maybe buying a new board can fix the problem.
- It can be possible that somehow the pins in the charger have worn. Try holding it up by you after plugging it in and check what happens.
- Maybe it is happening because the charger is failing to sense the battery voltage, which means somehow you have blown a fuse. First, plug the charger into AC power and then plug it into the cart.
- There is a relay into the chargers. Taste it and make sure it’s alright. If it’s okay, then you do not have to change the charger. Maybe some necessary fixing can solve your problem.
Golf Cart Battery Maintenance
Proper maintenance is essential if you want your batteries to work sufficiently. Whether you have a Club Car, Yamaha, EZGO, or any other golf cart models, the batteries are needed to be kept in good condition.
The batteries need to dry, clean, and tight all time. Use a bristle brush and a mixture of water and baking soda and clean the batteries. The most important part is to take precautions while cleaning it.
For example, you can wear something to cover your eye to protect it from the mixture.
- Charge it with a proper charger at least up to 8 to 10 hours. To keep your cart healthy, try to charge it when you are done with it for the day, which means charge the batteries at night.
- You must know that your batteries must contain enough distilled water; otherwise, there can be consequences. But remember to fill the batteries when the charging is complete, and the charger is unplugged.
- Charge your batteries at least once every 45-60 days.
- Whenever you are discharging the batteries, make sure that the charge percentage is somewhere between 50-80 percent.
- Never charge a frozen battery.
- Keep an eye on the water levels. If it is lower, then fill it.
- Record the battery voltage of each of the batteries so that it will be easy for you when you buy another one in the future.
Club Car Overcharging Problems
Overcharging can cause severe damage to your cart’s batteries. Sometimes even automatic chargers can malfunction and fail to turn itself off. In this situation, if you try to drive the car, it can cause even more damage.
Try the following fixes and see if they work:
- It can be a wiring problem. At first, locate the yellow cable, coming from the battery regulator, and unplug it. Now you will be able to see where the voltage is coming from.
- Check all the grounding of your cart.
- Sometimes, the relay inside the battery fails. Changing it can completely solve the problem.
- Maybe the OBC is outdated. The OBC of golf carts is responsible for the cart’s charging. It should be fully functional to maintain your cart’s critical functions.
- Check all the terminals and make sure they are not damaged.
EZGO overcharging problems
These are the reasons why a EZGO golf cart can overcharge:
- Bad voltage regulator
- Charger Pins
How to fix EZGO overcharging:
- Replace the bad voltage regulator with a new one.
- Bad voltage regulators can also result from faulty grounding somewhere in the regulator or the starter generator. Try to fix it, and the overcharging problem will be initially fixed.
- Sometimes if the charger pins have been worn out, charging problems like this can occur.
- If the relay inside the changer is not OK, it will not work correctly. Change the relay or buy a new car.
- An outdated OBC can cause several problems. Update it as soon as possible to stop your golf cart from malfunctioning.
- You have to run tastes on your charger to find out if it is alright. If the results are negative, then just replace the batteries. And if the batteries are new, then try to repair them as soon as possible.
Yamaha G2 Golf Cart Overcharging Problems
Here are some basic troubleshooting you can perform in this situation:
Check if the starter is wired incorrectly. If the ground wire is at the f2 terminal and the wire comes from the solenoid is on the A2 terminal, the generator is active, so the regulator does not have enough time to shut the charger off.
- Somehow the key switch or the throttle switch is responsible for the overcharging. Any malfunctioning in that area can trick the voltage regulator and show it a specific voltage drop to think that the battery is not changed. So check the key switch and repair it immediately.
- Try to find out that if the terminal is longer in a good position or corroded.
- Don’t ignore connector crimps.
Yamaha G16 Golf Cart Overcharging Problems
The most common reason for overcharging of the g16 golf cart is the problematic voltage regulator. Maybe changing it will solve the problems.
There are some other things you can do in this situation:
- See if all the wire connections with the batteries are intact.
- Please make sure the terminals are not damaged; they are clean.
- Check the relay inside the charger.
- Inspect the cart thoroughly and find out if the fuse has blown or not
- Sometimes a bad battery can also be the reason why your charger seems to be overcharging. Examine it and eliminate the bad batteries as soon as possible.
Yamaha G22 Golf Cart Overcharging Problems
These are the two main reasons why your Yamaha g22 golf cart is overcharging:
The battery voltage that the voltage regulator sees goes through a throttle switch or key switch. Any damage in that switch can show the battery a wrong voltage. Maybe in your case, the voltage regulator sees a drop in voltage due to the aforementioned reason. So check at first if the switch is alright.
The voltage regulator grounds and then ungrounds the green wire. That’s how the VR works. If VR grounds the green wire internally can be the main reason behind your problem.
In this case, if you try to charge the batteries anyway, then it can fry up. Don’t turn the power on until the VR is replaced or repaired.
