EZGO golf cart Controller Light is Flashing Like Crazy!

Hey everyone, I’m at my wit’s end here. My EZGO golf cart’s controller light is flashing non-stop, and I have no idea why. I’ve tried a few basic fixes, but nothing’s working. I’m desperate for some suggestions!

Response

Man, I feel your pain. I had the same annoying issue with my EZGO cart. After doing some serious sleuthing, I found a couple of things that actually worked. For me, checking the solenoid voltage did the trick.

Check Solenoid Voltage1Checked voltage and it matched$010-15
Bypass the Reed Switch1Bypassed the switch and cart moved$07-10
Check for Loose Connections1Fixed a couple of loose connections$010-15

Symptoms

  • Controller light flashing like a disco ball
  • Cart either refuses to move or moves in fits and starts
  • Battery drains faster than a bathtub with the plug pulled

Possible Causes

  • Faulty or mismatched solenoid
  • Loose or corroded connections
  • Reed switch malfunction
  • Controller programming issues

Solutions that Worked

1. Check Solenoid Voltage

What I Did:

Used a multimeter to check if the solenoid voltage matched the controller’s specifications.

Outcome:

The cart started behaving like it should—no more flashing lights.

Personal Experience:

I was skeptical, but checking the voltage actually worked. It was a game-changer.

Estimated Cost:

$0

Time Needed:

10-15 minutes

Steps:

  1. Turn off the golf cart and disconnect the battery.
  2. Locate the solenoid, usually near the battery compartment.
  3. Connect a multimeter to the solenoid terminals.
  4. Turn the cart back on and read the voltage on the multimeter.
  5. Compare this reading with the voltage requirements specified in your controller’s manual.

Expert Tip:

Always disconnect the battery before messing with electrical components. Safety first!

2. Bypass the Reed Switch

What I Did:

Temporarily bypassed the reed switch to diagnose the issue.

Outcome:

The cart started moving like it was brand new.

Personal Experience:

I couldn’t believe it. A simple bypass and the cart was back in action.

Estimated Cost:

$0

Time Needed:

10-15 minutes

Steps:

  1. Turn off the cart and disconnect the battery for safety.
  2. Locate the reed switch, often found near the pedal box.
  3. Use a jumper wire to connect the two terminals of the reed switch, effectively bypassing it.
  4. Reconnect the battery and turn on the cart.
  5. Test to see if the cart moves normally.

Expert Tip:

This is a diagnostic step. If bypassing the reed switch fixes the issue, you’ll likely need to replace it for a long-term solution.

3. Check for Loose Connections

What I Did:

Inspected all electrical connections and tightened any that were loose.

Outcome:

The flashing light stopped, and the cart ran smoothly.

Personal Experience:

I found a couple of loose wires, tightened them up, and voila! Problem solved.

Estimated Cost:

$0

Time Needed:

10-15 minutes

Steps:

  1. Turn off the cart and disconnect the battery.
  2. Open the battery compartment and inspect all visible connections.
  3. Use a wrench or screwdriver to tighten any loose connections.
  4. Don’t forget to check the connections at the controller and motor as well.
  5. Reconnect the battery and test the cart.

Expert Tip:

Corroded connections can also cause issues. If you see any corrosion, clean it off with a wire brush before tightening.

Golf Cart Models Where This Worked

  • 1999 EZGO TXT Standard with Alltrax NPX controller, upgraded to 48V
  • General EZGO models (No specific years mentioned)

Bonus Info: Controller Programming

If you’ve recently swapped out major components like the charger or solenoid, you might need to reprogram your controller. This is often overlooked but can solve a multitude of issues, including flashing lights.

I hope this helps anyone who’s as frustrated as I was. If you’ve found other solutions, please share! We’re all in this together.
