Personal Plea for Help
My Club Car golf cart just can’t handle hills anymore. It’s like it’s gasping for air every time I try to go uphill. I’ve tried a few things, but I’m still stuck.
Response
What really made a difference for me was performing individual load tests on each battery. I found a weak one and replaced it.

Solutions that Worked
1. Perform Individual Load Tests on Batteries
What I Did: Performed load tests on each battery using a specialized load tester.
Outcome: Identified the weak batteries and replaced them.
Personal Experience: After performing the load tests, I found that one of my batteries was significantly weaker than the others. Replacing it solved the issue.
Estimated Cost: $0
Time Needed: 10-20 minutes
Steps:
- Disconnect each battery from the cart.
- Use a specialized load tester to check each battery individually.
- Note down the readings for each battery.
- Compare the readings to identify any weak batteries.
- Replace any weak batteries.
Expert Tip: Individual load tests can help you pinpoint which battery is causing the issue, saving you the cost and hassle of replacing all batteries. Make sure to use a specialized load tester for accurate results.
2. Replace the Bad Battery
What I Did: Replaced the bad battery in the cart.
Outcome: The cart’s performance improved significantly.
Personal Experience: I noticed one of my batteries had a lower voltage. Replacing it made a world of difference.
Estimated Cost: $100-$200
Time Needed: 30-60 minutes
Steps:
- Identify the bad battery through voltage tests.
- Disconnect the cables from the bad battery.
- Remove the bad battery from the cart.
- Place the new battery in the cart.
- Reconnect the cables to the new battery.
- Test the cart to ensure the problem is resolved.
Expert Tip: Always check the voltage of each battery. A single bad battery can significantly affect the cart’s performance. Also, make sure to properly dispose of the old battery.
3. Check Battery Cables Gauge
What I Did: Checked the gauge of the battery cables and upgraded to a thicker gauge.
Outcome: The cart started performing better uphill.
Personal Experience: Upgrading to a thicker gauge made a noticeable difference.
Estimated Cost: $20-$50
Time Needed: 15-30 minutes
Steps:
- Inspect the current gauge of your battery cables.
- Measure the length needed for new cables.
- Purchase thicker gauge cables if necessary.
- Disconnect the old cables.
- Replace the old cables with the new ones.
- Reconnect the batteries and test the cart.
Expert Tip: The gauge of the battery cables can affect the power output. Consider upgrading to a thicker gauge if you’re experiencing significant power loss. Make sure to measure the length needed for new cables accurately.
4. Clean All Connections
What I Did: Cleaned all battery and motor connections.
Outcome: The cart’s performance improved.
Personal Experience: Cleaning all the connections made the cart run smoother.
Estimated Cost: $0
Time Needed: 10-20 minutes
Steps:
- Disconnect the batteries.
- Use a wire brush to clean all battery terminals.
- Use electrical cleaner to remove any corrosion.
- Clean motor connections using the same method.
- Reconnect the batteries and test the cart.
Expert Tip: Dirty connections can reduce the amount of amp output, especially under load from things like hills. Always make sure your connections are clean. Using an electrical cleaner can help remove stubborn corrosion.
5. Check and Adjust Potentiometer (Pot Box)
What I Did: Checked and adjusted the potentiometer.
Outcome: The cart started running smoothly.
Personal Experience: Adjusting the potentiometer helped with the jerky starts.
Estimated Cost: $0
Time Needed: 10-20 minutes
Steps:
- Locate the potentiometer, usually near the pedal assembly.
- Use a multimeter to test its output.
- If the output is not smooth, adjust or replace the potentiometer.
- Test the cart to ensure the problem is resolved.
Expert Tip: A malfunctioning potentiometer can cause jerky starts. Test it for smooth output and adjust as necessary. If you’re not comfortable doing this yourself, consider seeking professional help.
