(4 Reasons) Why your Yamaha Golf Cart is Not Charging

Yamaha Golf Cart is Not Charging

Why is my Yamaha Golf Cart Not Charging?

The most likely reasons why a Yamaha golf cart is not charging are:

  1. The battery charger is damaged
  2. Loose connections
  3. Corrosion of the battery terminals
  4. Fault with the Receptacle 


Battery Charger Problems:

Your golf cart will not start charging if your charger won’t turn on. And this happens if you don’t recharge the battery for a long time. So, the current charge that they’re carrying right now might be just too low for the charger to detect.

A minimum of 25-30 volts is required to wake up the charger and for it to begin charging your Yamaha Golf Cart.

A failure in the “brain” of the charger can also cause the charger to take very long to start charging or to recharge fully. This can be solved by an easy replacement and doesn’t even require many bucks. 


Wiring problems:

Frayed or weak connection in the batteries leads to fast power loss. It causes the charge to drain out very quickly and also causes failure in the battery.

To avoid this, check every batteries’ terminal for corrosion. Corrosion build-up hinders the electrical flow and hence causes issues with charging.

When you plug in the charger, and it just won’t start charging, or nothing happens, most plausibly, the problem is with the batteries or their connection.

Check your batteries using a voltage tester to confirm if you’ll require a replacement. 

If your Yamaha golf cart just won’t charge completely, then the problem is definitely with the batteries. A replacement will solve this issue.   


Yamaha Golf Cart Charging Problems

Basic reasons that can cause problems during charging are:

  • Problem with the Receptacle 
  • Corrosion 
  • Pack Voltage


Problem with the Receptacle

A dirty and loose receptacle can create problems even with new sets of batteries. Handle this by getting it tightened and cleaned by the dealer. 

Besides this, it also happens that the plastic covering on one of the prongs can break. This does not allow a full connection. An easy repair can avoid a charger replacement. 


Corrosion of the battery terminals

Check the battery terminals and the charger lead for any corrosion build-up. Corrosion can prevent charging and cause failure in the batteries. Always make sure that corrosion doesn’t take place.

  • Check for corrosion in the AC power and battery set.
  • Remove the corrosion, and then the batteries should charge fine. 


Pack Voltage

Other than these two mentioned issues, low voltage can also cause charging problems. If the pack voltage is too low, the charging cycle will not complete. Hence the batteries will drain out faster and won’t charge fully. This can be fixed by providing enough voltage for the charger to begin charging.

You can monitor the light display on the charger to figure out where the problem is. The error lights are the second and third light indicators.

If the error light is flashing red, try reconnecting the charger and then charging the battery again. 

The first light indicates power. It will turn on when the charger gets plugged into the AC power. 


Check the voltage of your batteries. If it is showing 48 volts, then the golf cart should charge correctly.


In case of decoloration and if it has lost its charge, then most probably the batteries have become damaged. This can be caused due to the use of the wrong charger. Make sure to use the original Yamaha charger with the label of 48 volts. 


How to fix a Yamaha Golf Cart that is not charging?

You can fix your Yamaha golf cart if it is not charging by considering the following facts and steps:

The Golf cart will not start charging until and unless the charger turns on. If the battery takes a lot of time to recharge or gets drained after getting the charge, this prevents it from fully charging.

The charger has a requirement of a minimum volt that allows it to recharge the battery. As mentioned earlier, the minimum volt must be around 25-30 Volts for the charger to recharge the battery. 

Another reason your golf cart won’t charge could be because nothing would happen even after you plug in the charger.

The most likely cause behind this problem is the connection problem with batteries.

You can confirm and test this problem using a voltmeter. After this test, you can decide if the golf cart requires a battery replacement.  


Tools Required

  • Voltage tester: this will help you determine whether the voltage is too low. In which case, a replacement will be required. 
  • Battery cleaning agent: This will help you to remove the corrosion. Follow these steps to remove corrosion in battery terminals:
  1. Disconnect the cables.
  2. Look for corrosion. Corrosion can be easily spotted. If you find the terminals to be peeled or dried and have a greenish or brownish coating, that is your target. 
  3. Apply the cleaning agent to the affected area. Preferably go for the commercial-grade cleaners. They will clean them and neutralize the terminals for further preventing corrosion. 
  4. Use a brush to scrub off the corrosion and then rinse it. Make sure the cleaner doesn’t fall on other parts around the battery. 

This will help the normal functioning of the battery.

  • Often, the G1 golf cart doesn’t charge because of a bad receptacle. Make sure that the receptacles fit tightly and are clean. If not, then you can get the receptacles cleaned and tightened. 
  • Check the plastic coverings on the prongs. A broken cover can also build problems. This can be repaired easily, and your Golf cart will charge normally.
  • The next thing to watch out for is corrosion. Corrosion mainly occurs at the battery terminals. Corrosion is a big reason why batteries don’t work properly. Prevent corrosion from forming anywhere on or around the batteries. Corrosions often lead to a drop in voltage, which hinders the recharge process. Clean corrosion if it occurs, and then your problem should be solved. Corrosion can be cleaned easily and avoided for future problems.

Improper connections in the batteries lead to power draining. This doesn’t allow the battery to charge completely. The improper connection also leads to the failure of the battery. 

The first reason that causes hindrance in connection is corrosion. It should be prevented at all costs for the normal functioning of the batteries. Clean the battery terminals in case it corrodes. 

There may be a direct problem in the battery itself that will require a replacement.

To check if your batteries are fine or not, you can use a voltage tester. Mostly the problem lies with the batteries; when they don’t recharge fully or even connected to the charger, nothing happens. In this case, replacement is the only solution. 

Other than connection issues and problems in the battery, the next problem could be with the pack voltage. Low voltage is one of the major causes that result in charging problems.

When the pack voltage is too low, the battery will not charge whatsoever.

Enough voltage should be provided to the charger to complete the charging cycle and ensure that the charge doesn’t drain out.

Corrosion is the first and the most common cause that results in charging failure. The battery terminals corrode easily, which should be taken care of.

Corrosion can be easily removed and be prevented as well. One can easily solve charging problems by removing corrosion build-up from their batteries.

These are the steps that you can follow to remove corrosion from the battery terminals:

  1. Disconnect the cables.
  2. Corrosion is easy to detect. A peeled, dried, brownish terminal end means that there is corrosion on the battery. That is the spot that has to be cleaned.
  3. Apply the cleaning agent to the affected area. Preferably go for the commercial-grade cleaners; they will clean them and neutralize the terminals to prevent corrosion. 
  4. Use a brush to scrub off the corrosion and then rinse it. Make sure the cleaner doesn’t fall on other parts around the battery. 
  • If your battery is clean and you don’t find any corrosion, the next step is to check the receptacles. A dirty receptacle can often cause a problem in the charging process. A dealer can help you with the cleaning of receptacles. 
  • After checking for corrosion and receptacles, look for the plastic coverings on top of the prongs. A broken plastic covering can also act as a hindrance in the charging cycle. Easy repair can easily solve this. 


Yamaha G16 Golf Cart not charging

The Yamaha G16 golf cart is known to have problems with charging when the battery charger is not putting out the required voltage.

At times, even after turning on the charger, nothing happens. This happens if the battery is not recharged for a long time. That’s because the charge that is currently present in the battery is too low for the charger to detect.


A minimum of 25 volts must be provided to the charger to start charging

 A bad or poor connection must be avoided. Often frayed connections in the battery can lead to the battery not charging at all.

Corroded terminals can cause this problem and also lead to battery failure. Corrosion should be cleaned off of the terminals for the normal working of the batteries.

A clean receptacle should also be maintained to ensure the charging cycle completes to recharge the battery fully.
