Working? Here’s How to Fix It

Having trouble getting your Club Car golf cart charger to work?

You’re not alone. Many golf cart owners face this common issue, often due to low battery voltage, wiring problems, or a malfunctioning onboard computer (OBC). Below, you’ll learn why your golf cart charger may not be working and the steps you can take to get it running again.

Why Do Club Car Golf Cart Chargers Fail?

Automatic golf cart battery chargers typically require 20 to 35 volts to detect the battery and begin charging. If your batteries have been sitting idle without charging (or are brand new and haven’t been charged yet), their voltage might be too low for the charger to engage.

1. Manually Charge the Batteries (If Your Cart Won’t Drive)

● Use a 6V or 12V Car Charger: Connect a standard car battery charger to each battery for a couple of minutes. This quick boost raises the battery voltage to a level your Club Car golf cart charger will recognize.

● Watch the Time: Usually, 15–20 minutes is enough to bring the voltage up. Avoid overcharging; you only need enough voltage for the golf cart’s charger to detect the batteries and start its cycle.

2. Check Every Battery Connection

Loose or corroded connections can prevent your charger from functioning:

● Inspect the cables: Ensure all battery cables are tightly connected and correctly wired.

● Clean terminals: If you see rust or corrosion, clean the terminals with baking soda and water, then dry thoroughly before reattaching cables.

● Verify wiring: If you recently installed new batteries, double-check that each cable is in the correct sequence.

3. Consider the Onboard Computer (OBC)

Understanding the OBC

All 48-volt Club Car models built since 1995 include an onboard computer (OBC) that controls when the battery charger starts and stops.

Common OBC Issues

● No “click” sound: If the total battery voltage is over 35 volts, you should hear a relay “click” when you plug in the charger.

● Charger fails to turn on at all: If your batteries are charged above 35 volts and you still don’t hear the click, the OBC or a fuse may be malfunctioning.

Rare Relay Failures

A bad relay (open coil) in the charger itself is uncommon but can happen. If you’ve ruled out battery voltage and OBC issues, consider testing or replacing the charger relay
