1. Chargers Flashes Two Red Light when Plugged in And Doesn’t Charge

When your charger flashes two red lights and doesn’t charge, it could be that the battery voltage is too low for the charger to detect a charge or a connection problem.

How to Fix Poor Charging Issues:

1. Check the voltage of each battery. When you locate the ones with a low charge, use a smaller auto charger to boost the charge and plug back the Ezgo charger.
2. Check that your battery terminals are correctly connected.
3. Ensure the charger is properly plugged in and there aren’t any loose cables.
4. If the issue continues, take the charger and cart to an expert for further checkup.

2. Charger Light Flashes Repeatedly 5 to 6 Times and Goes Out

This problem can often occur when the charger is not properly connected to the AC circuit. Your golf cart battery charger can still flash when it detects some DC charge from your battery when plugged in.

How to Fix Charger Light Repeated Flashes:

1. Ensure your charger is plugged into the AC power source and the plug pin isn’t faulty. 
2. If the plug pin is faulty, replace it.

3. Charger Doesn’t Make a Click Sound when Plugged Into the DC Power Source

When the charger doesn’t make a click sound after being plugged into a DC power source, it could be that the fuse is faulty.

How to Fix a Lack of Click Sound:

1. Disconnect the charger from the AC and DC power source.
2. Use a Phillips screwdriver to remove the screws that hold the charger case.
3. Use a voltmeter to check the fuse and DC cord to ensure continuity in the circuit.
4. Set the meter to continuity. You will hear a beep when the testers connect to the fuse. If you don’t hear a beep sound, the fuse is faulty and has to be replaced.

4. EZGO Charger Doesn’t Come On

When you notice these EZGO Golf Cart Charging Problems, you either have a low battery charge or battery connection problems.

How to Fix EZGO Charger not Starting:

1. Use a voltmeter to check your battery voltage and top them up using an auto charger before plugging back the EZGO charger.
2. Check if the battery terminals are properly hooked and that there are no frayed connections.

5. Charger Doesn’t Run Long Enough or Runs Too Long

If you plug in your EZGO charger and notice that it either runs too long or doesn’t run long enough, you might have a problem with its system. A failure in the charger’s “brain” can lead to your battery not knowing when to stop charging.

How to Fix:

The only option to fix this issue is to replace the component.

2. In cases where it is too low, use an auto charger to boost the charge. If the charge is high, try charging it when it has reduced.

3. Charger Makes a Clicking Sound but Doesnt Charge

If your charger makes a clicking sound and does nothing afterward, it shows that your charger knows it should start charging but is failing for some reason. It could either be a faulty battery connection or an internal system issue.

How to Fix:

1. Do a thorough checkup on the charger’s cable and battery terminal connections.
2. Clean off any dust residue on the battery terminals or charger cables.
3. If the charger is still making the click sound without charging. Take the charger to an expert for further check-ups and repairs.

4. 36v Ezgo Charger Won’t Turn Off After Full Charge

Dusty spade terminals, low voltage sensors on the charger, or a faulty OBC often cause this problem.

How to Fix:

1. Change the OBC panel.
2. Unplug your charger and give the OBC some moments to calibrate. Plug the charger back.
3. If the issue persists, open your charger and clean the spade terminals.
4. If the issue persists, change your charger.

How to Fix:

1. Unplug your charger from the DC and AC power sources.
2. Check that the batteries are clean and properly connected.
3. Top up your battery water levels if needed.
4. Give your charger some time to cool down, and ensure it is placed on a hard surface while charging.
5. Try charging again. If your charger continues overheating and giving off a smell, contact a professional for more help.

Causes of Charging Problems with EZGO Golf Carts

Charging problems can occur on EZGO golf carts for the following reasons:

Faulty Batteries

For a reasonable time, most complaints of charging problems on EZGO golf carts have been caused by faulty batteries. Ez Go chargers are designed with self-direct technology, allowing them to start charging when plugged into the golf cart automatically. However, when the golf cart battery is faulty, the charger can not detect the battery and doesn’t charge. The battery is too low.

In cases where your battery charge is too low, your EZGO charger will not be able to detect your battery and hence won’t charge.

Battery Connection Problems

Your EZGO Golf Cart is an electrical environment; any loose or faulty wiring or residue build-up on the connections or terminals can cause charging problems by limiting the current flow from the battery to the charger.

Faulty Charger Plug Pin

Most times, the plug pin of EZGO chargers can become faulty, preventing them from picking up charge from the circuit.

Blown Charger Fuse

When the fuse of an EZGO charger is frayed or faulty, the charger won’t work.

Solutions to Charging Problems with EZGO Golf Carts

1. Check the golf cart batteries; if they are too old, replace them. 
2. Cleaning up your battery terminals as dust inhibits the proper flow of current from the battery to the charger.
3. Ensure the terminals are properly connected.
4. If your golf cart battery is too low, use a factory charger to charge each battery separately to boost the charge. When it picks up, reconnect your EZGO charger.
5. Check the EZGO charger plug pin to ensure it is not faulty. If it is, replace it.
6. Check the EZGO charger fuse and replace it if it is blown.
