Why a EZGO Golf Cart Won’t Charge/Losing Charge

EZGO golf cart battery not charging

Why is my EZGO golf cart not charging?

Your EZGO golf cart may not be charging due to problems with batteries or the charger. It could be due to a lack of battery voltage, a faulty charger or a lack of hydrogen in the batteries.

A charger problem can also be associated with the charger making a loud clicking noise, failing to stop charging after the batteries have attained full charge or not charging fully.

If the problem is with the charger, you should do a charger replacement.

  • No battery voltage
  • No sign of life in the charger
  • Lack of hydrogen in batteries
  • Loud clicking noise in the charger
  • The charger doesn’t stop charging or charge full
  • No battery voltage: Often, this happens when the batteries have been used continuously for a long time. Using a good battery and connector cable wires can solve the problem.
  • Faulty charger: If the charger fails to indicate charging or does not kick on when it’s plugged into the golf cart, this is often due to a bad battery or bad connection or both.

If you’re done with checking the connections and fixing them, but the problem persists, identifying the faulty battery and replacing it is the solution.


Why does my EZGO battery keep dying?

Your EZGO battery may keep dying because of a faulty voltage regulator, loose terminal connections, or dead battery cells.

  • Faulty voltage regulator
  • Loose terminal connections
  • Dead battery cells
  • Battery not getting charged
  • Faulty voltage regulator: Check the voltage regulator for signs of damage. Replace the defective unit with a new one.
  • Loose terminal connections: Check the connections at all battery terminals and tighten the loose connections. Clean up all traces of corrosion and do replacements if needed. You might also remove and clean the battery cables used for the connection.
  • One or more dead battery cells: Put the cart battery on slow charge and take it to your nearby auto parts store to seek assistance in getting a load test done to check for dead battery cells.
  • Battery not getting charged: This could be because the positive connection of the charger socket isn’t connected to the positive terminal of the non-charging battery. To check for this wiring error, determine the pack voltages at the pack positive and negative terminals, as well as the charger receptacle. If the receptacle reading is low, you will have this problem.


How to fix an EZGO RXV that won’t charge

An EZGO RXV golf cart won’t charge because of a dead battery, low battery pack voltage, a non-charging charger or a faulty battery cable.

  1. Measure the positive and negative voltages of the battery pack using a multimeter. Depending on the charge level, it should read between 46 to 50 volts for a 48-volt cart. If the reading is abnormally low such as 16 volts or 24 volts, check the voltage of each battery individually by hooking on to a regular charger. Also, check the water level in each battery.

If the reading of each battery is normal and is around 12.4 volts, the problem could be with one or more faulty battery cables.

Identifying these cables and replacing them with new cables that meet the requirements will resolve the problem.

If a battery shows a voltage reading of around 9 volts or less, then it’s a sign of that particular battery failing. Consider changing the battery.

  1. Check for a blown-out fuse on the cable that is connected to the solenoid and replace it. You might also want to check if the solenoid housed on the motor controller is getting any power.
  2. Inspect the key switch and verify if it’s functioning properly. If not, get a new one fitted in its place.
  3. Replace the charger if you notice that it’s making a loud clicking noise or doesn’t charge fully.


How to fix an EZGO TXT that won’t charge

Some reasons why an EZGO RXV golf cart will not charge could be because of a dirty charging port, loose or broken wire, a blown-out fuse or a problem with the auxiliary contact. 

  1. Clean the charging port so that it’s free of dust and dirt accumulation. Sometimes, dust and dirt can prevent proper charging.
  2. Check for a broken or loose wire of the charger as well as battery cables. If your charger wire is broken or the battery cables are damaged, they have to be replaced. If the battery cables are loose, tighten them. Also, check for corroded terminals and set them right.
  3. Check the fuse connection on the white lead from the battery’s charging port. The charging will not take place if this is blown out. Replace this fuse if needed.
  4. Inspect the safety interlock grey wire that is connected to the battery pack that has a black sensor connected to it. If the connection is corroded, cleaning it may help.
  5. Remove the cart plug and check if there is anything jammed between the side of the shroud and the pins that prevent the plug from going in completely. There are chances of small objects getting stuck and obstructing the charging process.


36V EZGO won’t charge

A 36 V EZGO may not charge due to the reasons given below.

  • The charger receptacle may have worn out connectors or Radsok. You can plug in a good charger and hold the cord end that is plugged in a little high so that good contact is established. If you notice the charger coming on after a minute, the connectors need a replacement for charging to take place effectively.
  • The charger receptacle voltage of the cart doesn’t match the battery pack voltage as it should.

If there is no voltage at all, the fuse in either the white or black wires that connect the battery pack and the receptacle might be blown-out. Identifying the blown-out fuse and replacing it with an identical one will resume the charging.

If the voltages match, ensure that negative Radsok is clean on the outside. The charger senses the battery pack voltage at this point through the auxiliary contact. So, if this Radsok is damaged, the auxiliary contact will not make any contact and the Radsok must be replaced.

  1. Check for a clicking sound by the relay in the charger when it’s plugged to the golf cart. If you don’t hear this, it means the charger is not able to sense the battery pack. On the other hand, if the clicking sound occurs after a few seconds delay, the diodes in the charger are shorted and have blown out the fuse in the charger.
  2. Inspect the charger to see if it clicks occasionally and flashes the red light twice. If this happens, it may be faulty. Consider replacing the present charger with a DPI charger.
  3. The charger may not kick on because the batteries do not have any voltage. You can consider charging them two at a time if you have a 12-volt charger for around 20 minutes. The batteries should never be allowed to discharge below 20%. There is no need to disconnect each pair from the pack.
  4. Check if the lug and wire of the cables connecting the batteries and the receptacle are in good condition. If they are out of position or corroded, the charging can get hampered. Clean the lugs and get the cables replaced. It’s a good idea to change the cables every time you change the batteries.


EZGO TXT 48 won’t charge

A 48VEZGO may not charge due to the reasons given below.

  1. If the charger indicates a red light that blinks twice, then it’s likely to be defective. This may be why the cart is not charging. Replace the charger with a DPI charger.
  2. The reed switch is malfunctioning or not working at all resulting in a charger receptacle failure. This is a magnetic switch present in the receptacle that serves as the input for the solenoid activation circuit of the cart.

If your cart has a triangle-shaped plug, there is no reed switch for the receptacle. If the receptacle fails, apply 48 volts to the small wire at the receptacle so that the charger interlock is bypassed.


EZGO gas golf cart won’t charge the battery

The battery of an EZGO gas golf cart won’t get charged if the wire connections on the voltage regulator are corroded or broken by the crimp. In this case, getting the connections set right fixes the issue.

Sometimes, the voltage regulator may be faulty and need a replacement. To check if the regulator is defective, remove the green wire connecting the generator and the stator at the generator end.

Get the engine running, ground the disconnected end and check the voltage rating using a voltmeter. If the reading isn’t approximately 16 volts and stays at around 12 volts, the regulator is shot.


1995 EZGO won’t charge

Charge two batteries at a time with a 12-volt charger and then use the auto golf cart charger to resume the charging. The battery pack must have at least 28 volts for the cart charger to be able to kick in.

Also, ensure that the battery plates have at least 1/4 inch of distilled water above them before charging. The balance can be topped off after charging.

If the batteries are close to dead, you may need to charge them for about two and a half hours.


1998 EZGO won’t charge

  • The controller may be at fault and so getting it replaced may help.
  • Check if the wires that connect to the motor or controller feel hot. If so, they are likely to need a replacement.
  • If the battery pack voltage is lesser than what it should be, one or more batteries may be failing. Test the voltage of each battery separately to check for this.
  • The gauge in the charge meter is faulty and prevents the meter from working effectively. It’s worth changing the meter in this case.

To know if you have to change the meter, charge the battery pack fully and flip the Run/Tow switch to Tow mode. Disconnect one of the battery cables in the center of the pack and reconnect it after a couple of minutes. This resets the meter. Check the battery pack reading once again and if it still doesn’t show the desired result, change the meter.


1999 EZGO won’t charge

  • One or more batteries may be completely dead or have very low voltage. In this case, you will have to charge these batteries separately with another charger until they pick up a desirable voltage. You can then connect them to the battery pack and resume the charging with the golf cart charger. In some cases, you may have to change the batteries.
  • If your charger is connected to the terminals of a 6-volt battery and your meter doesn’t show a reading of over 6 volts when the charger is functioning, it’s likely that the charger is malfunctioning and has to be changed.
  • The starter-generator or the voltage regulator is faulty and has to be changed. To identify what needs to be changed, disconnect the green wire connected to the starter-generator. Ground this wire to one of the batteries and turn on a meter on the same battery. With the cart in a neutral position, rev up the motor. If the meter reading is between 16 and 17 volts, the problem is with the voltage regulator else the starter-generator is defective.


2003 EZGO won’t hold charge

  • The contact flange present in the male handle is stuck and hence not making contact. Pulling it out to get it released will help to make contact and allow the charging to take place.
  • Inspect the auxiliary contact in the plug of the charger. The charger won’t work if the contact doesn’t touch the negative terminal on the outside. The contact may be dirty or could have got bent because of the insulator sleeve on the negative terminal.
  • The negative connection that has the charge wire attached is not making good contact or is dirty. Tightening the connection if it’s loose and cleaning it can help.
  • The charger may be faulty. Check this by plugging the charger into the golf cart and see how much it charges the battery pack using a digital voltmeter. Alternatively, you can use another charger to do the charging and see if there is a difference. Allow the charger to charge the pack fully and shut down on its own.
  • There may be corrosion between the connections. Remove each connection and clean all the terminals and lugs. Reconnect and apply some anti-corrosive electrical contact spray on the contacts without oozing between the terminals.


2008 EZGO won’t hold charge

  • The two batteries to which the lights of the golf cart are connected may be losing charge because the lights have been on for long when the cart is parked. Charge those two batteries separately using a 12-volt automotive charger so that their SoC matches the remaining pack. Follow up with a full charge of the entire pack using the cart charger and allow the charger to shut off automatically.
  • When all six batteries connected in series are charged using a 36V charger, they should have almost the same voltage. Check the voltage of each battery individually using a voltmeter. Replace the faulty battery with another that has more or less the same condition, age and amp-hour ratings as the other batteries.


2009 EZGO won’t hold charge

  • Check the battery pack voltage when the cart is at rest and after 12 hours when it was last charged. Turn the key to the forward position and note the dip in voltage with the meter still connected. Also, check each battery voltage individually using a digital voltmeter. Replace the battery if it’s faulty.
  • Consider replacing the 4-battery setup with a 6-battery setup as the latter offers more range for the cart.
  • There may be a solenoid or wiring problem. Getting a new solenoid fitted or getting the wiring redone will resume the charging properly.


2010 EZGO won’t hold charge

One or more batteries are toast, which is why the cart doesn’t hold charge. Replacing them solves the problem. When batteries go dead often, they have to be charged individually to bring them to the point of being able to charge using the cart charger. A complete discharge test often takes close to 110 minutes. If it gets done at a lesser duration, it’s a sign of toast batteries.


2012 EZGO won’t hold charge

  • There may be a failing cable or a faulty battery that must be replaced. Check the battery pack voltage using a multimeter. For a 48-volt cart, this should be between 46 to 50 volts based on the charge level. If the reading ranges between 16 to 24 volts but each battery has around 12.4 volts reading, the problem is with the cable. But, if the battery voltage is around 9 volts, you have to attend to the battery.
  • The fuse in the charger port may have blown out. You’ll have to do a complete port replacement. Consider stripping off a little insulation from the blue wire that comes out of the charging port and connect the red wire also coming out of the same port to the blue wire through a 30A pigtail fuse.
