I need your assistance with my golf cart that just comes to a complete stop whenever I depress the throttle all the way. Has anyone else faced this and found a working solution?
Response
Sounds like a classic case with the MCOR or pedal sensors. I had a similar issue last year. Checking and possibly replacing these parts might just do the trick for you.

Detailed Solutions that Worked
1. MCOR Replacement or Adjustment
What I Did: Identified and rectified issues with the MCOR.
Outcome: The golf cart resumed normal operation without unexpected stops.
Personal Experience: Troubleshooting revealed a faulty MCOR. Replacing it with a high-quality component fixed the problem.
Estimated Cost: $50 – $150
Time Needed: 45 – 90 minutes
Detailed Steps:
- Locate the MCOR: Find the MCOR near the pedal assembly. Refer to your cart’s manual for the exact location.
- Safety First: Always disconnect the battery before starting any electrical work.
- Testing: Use a multimeter to test the MCOR’s functionality. Look for signs of wear or damage.
- Replacement/Adjustment: If faulty, replace the MCOR with a recommended part. If it’s an adjustment issue, follow the manufacturer’s guidelines to recalibrate.
- Reconnection and Testing: Reconnect the battery and test the cart’s response to throttle input.
Expert Tip: Use dielectric grease on electrical connections to prevent corrosion.
2. Battery Connection Check
What I Did: Ensured all battery connections were secure and clean.
Outcome: Enhanced electrical connectivity, eliminating the stopping issue.
Personal Experience: Found that loose connections were causing power fluctuations, which were resolved after proper tightening and cleaning.
Estimated Cost: $0 (if done personally)
Time Needed: 20 – 40 minutes
Detailed Steps:
- Battery Inspection: Open the battery compartment and visually inspect all connections.
- Tightening Connections: Use a wrench to tighten all connections. Ensure they are snug but not overly tight.
- Cleaning Corrosion: If there’s corrosion, clean it off with a mixture of baking soda and water, then rinse and dry.
- Final Testing: After reassembling, test the cart for consistent power delivery.
Expert Tip: Regularly check battery water levels and refill with distilled water as needed.
3. Pedal Position Adjustment
What I Did: Corrected the pedal assembly for proper return to zero position.
Outcome: Resolved the stalling issue when the pedal was fully depressed.
Personal Experience: Older carts often have issues with pedal return, causing unexpected stops.
Estimated Cost: $0 (if done personally)
Time Needed: 20 – 40 minutes
Detailed Steps:
- Pedal Assembly Check: Examine the pedal assembly for any misalignment or wear.
- Adjustment: Adjust the spring tension or realign the pedal to ensure it returns smoothly to the zero position.
- Lubrication: Apply lubricant to moving parts to ensure smooth operation.
- Testing: Test the pedal’s response and the cart’s performance.
Expert Tip: Regular lubrication of the pedal assembly can prevent sticking and ensure longevity.
