The Charger LED is Stuck Flashing Red and Green
Situation
The lead acid batteries do not have enough power to move the cart.
Common Cause
The most common cause is when the batteries in your golf cart drop below the minimum safe charging voltage – 18V for 36V carts and 24V for 48V carts.
This scenario is common, especially in carts that haven't been charged for a prolonged period or have been completely drained. In such cases, a standard golf cart charger is unable to initiate the charging process due to the low voltage.
How To Fix
- Disconnect the Charger: Disconnect the charger from your cart.
- Connect a Trickle Charger: Connect the positive and negative leads of an automotive trickle charger to battery 1 in your golf cart. (The wires between each battery do not need to be disconnected)
- Charge: Turn on the trickle charger and let it charge for approximately 30 minutes.
- Repeat for Each Battery: Repeat steps 2 and 3 for each battery.
-
Check Voltage: Use a multimeter to check the voltage over the entire battery pack.
- If your pack voltage is testing above 18 volts for 36-volt carts or 24 volts for 48-volt carts, you may resume charging with your golf cart charger.
- If your pack voltage remains under the minimum, repeat charging each battery individually with the trickle charger.
