Can anyone help me out here? I’m at my wit’s end with my 1993 Club Car DS. Whenever I’m going uphill or putting it under any load, the voltage just plummets. It’s like it loses all its power. I’ve tried a few things, but nothing’s working. Has anyone faced something similar? Any advice or tips would be a lifesaver!
Response
For me, it was a mix of old batteries and a finicky FNR switch. After a thorough check and some tweaks, it was like a new cart. Definitely look into these areas, and don’t forget to check the wiring too!

Symptoms
- Significant slowdown, especially on inclines.
- Noticeable voltage drop when the cart is under load.
- Inconsistent performance, particularly in challenging terrains.
Possible Causes
- Batteries losing their ability to hold a charge.
- Malfunctioning or misaligned Forward and Reverse (FNR) switch.
- Electrical resistance in wiring or solenoid components.
Detailed Solutions that Worked
1. Battery Replacement
- What I Did: Replaced the old, underperforming batteries.
- Outcome: Marked improvement in cart performance, especially uphill.
- Personal Experience: Realized the old batteries were the weak link.
- Detailed Steps:
- Safety First: Disconnect the power source to avoid any electrical hazards.
- Battery Assessment: Use a multimeter to check each battery’s voltage.
- Removal Process: Carefully remove the old batteries, noting their arrangement.
- Installation: Place the new batteries, ensuring they are correctly oriented.
- Connection Check: Double-check all connections for tightness and correct polarity.
- Final Testing: Test the cart on various terrains to ensure consistent performance.
- Expert Tip: Consider upgrading to higher capacity batteries for longer life and better performance. Also, keep the battery area clean to prevent corrosion.
2. FNR Switch Inspection
- What I Did: Adjusted and fixed the FNR switch for better contact.
- Outcome: Resolved erratic voltage drops and control issues.
- Personal Experience: Found that improper FNR switch alignment was causing issues.
- Detailed Steps:
- Locate the FNR Switch: Usually under the seat or dashboard.
- Inspection: Check for any visible damage or misalignment.
- Adjustment: Realign the switch for proper contact and operation.
- Testing: Move the switch between positions and listen for a definitive click.
- Secure the Switch: Tighten any loose components to ensure stability.
- Expert Tip: Regular lubrication of the switch can prevent sticking and wear. Also, consider replacing the switch if it shows signs of excessive wear.
3. Voltage Testing Under Different Conditions
- What I Did: Conducted comprehensive voltage tests in various scenarios.
- Outcome: Identified specific conditions causing the voltage drop.
- Personal Experience: Discovered that the voltage drop was more pronounced on inclines.
- Detailed Steps:
- Prepare the Multimeter: Set it to the correct voltage range.
- No Load Test: Check the voltage when the cart is stationary.
- Dynamic Testing: Measure the voltage while driving on flat ground and inclines.
- Data Comparison: Analyze the readings to pinpoint issues.
- Component Check: Investigate other components based on the test results.
- Expert Tip: Regular voltage testing can preemptively identify issues. Pay special attention to drastic changes in voltage readings under different conditions.
