My EZGO brake lights are not working anymore

Is anyone else having trouble with EZGO brake lights that just won’t light up? I’ve tried everything I can think of, but they’re still not working. It’s becoming a real safety issue, and I’m out of ideas. Has anyone successfully fixed this problem?

Response

I totally understand your frustration; I had a similar nightmare with my cart. What finally worked for me was double-checking the brake light switch and the wiring for any damaged or loose wires.

Symptoms

• Brake lights on the golf cart do not illuminate.
• Difficulty in identifying the correct wiring connections.
• Brake switch not functioning properly.

Possible Causes

• Loose or disconnected wiring.
• Malfunctioning brake switch.
• Incorrectly connected wires.
• Lack of understanding of the wiring diagram.

Solutions that Worked

1. Checking Wiring Connections

• What I Did: Ensured all connections were secure and properly attached.
• Outcome: The brake lights started working upon securing loose connections.
• Personal Experience: After inspecting the wiring, I found a couple of loose connections. Tightening them resolved the issue.
• Steps:
  1. Inspect all wiring connections related to the brake lights, including the switch, bulbs, and any connectors.
  2. Look for any signs of wear, corrosion, or damage on the wires.
  3. Tighten any loose connections and ensure proper attachment.
  4. Replace any damaged wires or connectors.
  5. Test the brake lights after securing the connections.
• Expert Tip: Regularly check and maintain wiring connections, as loose connections are a common issue in golf carts. Use dielectric grease on connections to prevent corrosion.

2. Using a Multimeter to Verify Switch Function

• What I Did: Checked the continuity and functionality of the brake switch with a multimeter.
• Outcome: Identified and fixed a malfunctioning brake switch.
• Personal Experience: Using a multimeter, I discovered the brake switch was not functioning correctly and replaced it.
• Steps:
  1. Use a multimeter to check the brake switch for continuity.
  2. Set the multimeter to the ohm setting and connect the probes to the switch terminals.
  3. Press the brake pedal and observe the reading. A change in reading indicates the switch is working.
  4. Replace the switch if it shows no continuity or inconsistent readings.
  5. Test the brake lights after replacing the switch.
• Expert Tip: A multimeter is an essential tool for diagnosing electrical issues in golf carts. Ensure the brake pedal is properly engaging the switch.

3. Identifying Wire Colors and Their Functions

• What I Did: Identified the function of each wire based on its color.
• Outcome: Correctly connected the wires, leading to functioning brake lights.
• Personal Experience: By understanding the wire colors, I managed to connect them correctly.
• Steps:
  1. Identify the color of each wire and its corresponding function.
  2. Consult a wiring color code chart specific to EZGO golf carts.
  3. Connect the wires as per their functions.
  4. Ensure that the positive and negative wires are not reversed.
  5. Test the brake lights after proper wire connection.
• Expert Tip: Familiarize yourself with standard wire color codes used in golf cart electrical systems. Incorrect wiring can lead to short circuits.

4. Consulting Wiring Diagrams

• What I Did: Referred to the EZGO factory accessories wiring diagram.
• Outcome: Correctly rewired the brake lights based on the diagram.
• Personal Experience: The wiring diagram was a great help in understanding the correct setup.
• Steps:
  1. Obtain the wiring diagram for your specific golf cart model.
  2. Compare the current wiring setup with the diagram.
  3. Correct any discrepancies based on the diagram.
  4. Pay special attention to the brake light circuit, including the switch and lights.
  5. Test the brake lights after rewiring as per the diagram.
• Expert Tip: Always refer to the manufacturer’s wiring diagram when dealing with electrical issues. Keep a copy of the diagram handy for future reference.
