My EZGO golf cart’s F&R switch wires are corroded. What Can I Do?

Hey everyone, I’m in a bit of a pickle here. My EZGo RXV golf cart’s F&R switch wires are showing signs of corrosion, and I’m not sure how to fix it. I could really use some advice on how to tackle this problem.


Yes I did find a few solutions that worked wonders. One of the most effective was upgrading the wiring to a heavier gauge. I replaced the existing wires connected to the F&R switch with wires of a larger diameter. This upgrade is aimed at improving the electrical conductivity and handling higher current loads more effectively. It’s a straightforward fix that can make a huge difference.

  • F&R switch wires showing corrosion
  • Golf cart experiencing electrical issues
  • Difficulty in switching between forward and reverse

Possible Causes

  • Aging and wear of electrical components
  • Corrosion due to exposure to elements
  • Inadequate wiring for current load

Solutions that Worked

1. Cleaning and Tightening Connections

What I Did: Inspected all connections for corrosion and cleaned them thoroughly. Tightened any loose connections.

Outcome: Improved electrical conductivity and resolved intermittent connection issues.

Personal Experience: This simple fix restored the functionality of the F&R switch.

Estimated Cost: $0 – $10

Time Needed: 15 – 30 minutes


  1. Inspect all electrical connections for signs of corrosion.
  2. Use a wire brush or sandpaper to clean the corroded areas.
  3. Tighten all loose connections with a wrench or pliers.
  4. Apply a corrosion inhibitor to prevent future issues.

Expert Tip: Regular maintenance and inspection can prevent corrosion-related problems. Using dielectric grease on connections can also help.

2. Replacing Corroded Wires

What I Did: Identified and replaced all the corroded wires with new, high-quality ones.

Outcome: Ensured reliable and safe electrical connections.

Personal Experience: Replacing the wires was a bit time-consuming but definitely worth it.

Estimated Cost: $20 – $50

Time Needed: 30 – 60 minutes


  1. Identify all corroded wires.
  2. Purchase suitable replacement wires.
  3. Carefully remove the old wires and replace them with new ones, ensuring proper connections.
  4. Test the golf cart to ensure everything is working correctly.

Expert Tip: When replacing wires, ensure they are of the correct gauge and type for your golf cart model.

3. Upgrading to Heavy Duty Solenoid

What I Did: Replaced the existing solenoid with a heavy-duty one to handle higher currents.

Outcome: Improved overall electrical system performance.

Personal Experience: This upgrade was particularly helpful for my modified golf cart.

Estimated Cost: $40 – $80

Time Needed: 45 – 90 minutes


  1. Choose a suitable heavy-duty solenoid for your golf cart model.
  2. Remove the old solenoid, taking note of all connections.
  3. Install the new solenoid, ensuring all connections are secure.
  4. Test the golf cart for proper operation.

Expert Tip: A heavy-duty solenoid is a good investment, especially for golf carts that are used frequently or have been upgraded.
