# NON CLUB CAR - My FORM Charger is Stuck Flashing Red and Green

Dealing with a charger that won't charge can be perplexing, but understanding the cause often simplifies the solution. Through troubleshooting with our customers, we have found a relatively common issue that has a fairly simple solution.

#### **Commonly Occurs After**

1. **Your cart was driven until it wouldn't drive anymore**
2. **Your cart has not been charged in a while**
3. **An accessory on your cart was left on**

#### **The Problem**

The primary issue arises 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 Confirm**

1. **Confirm ‘RUN’ Mode:** Confirm that the TOW/RUN switch (usually under the seat) is in ‘RUN’ mode
2. **Drive:** With the golf cart on, step on the pedal/accelerator\
   • If the cart does not move, the batteries are below the usable voltage

#### **How To Fix**

1. **Disconnect the Charger:** Disconnect the charger from your cart.
2. **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)
3. **Charge:** Turn on the trickle charger and let it charge for approximately 30 minutes.
4. **Repeat for Each Battery:** Repeat steps 2 and 3 for each of your batteries.
5. **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.
