Hey folks, I’m at my wit’s end here. My Alltrax golf cart controller light won’t stop blinking, and I’ve tried everything I can think of. Has anyone else been through this nightmare? I could really use some advice!
Response
. I was in the same boat until I decided to dig deep into the issue. One thing that really helped was checking the solenoid to make sure it clicks when the pedal is pressed.

Symptoms
- Controller light blinks in a pattern or continuously

- Faulty or worn-out solenoid
- Loose or corroded wiring
- Software glitches in the controller
Solutions that Worked
1. Check for Low Voltage
What I Did:
Used a multimeter to check the voltage of each battery in the cart.
Outcome:
The cart started functioning normally after charging the batteries.
Personal Experience:
I found that one of my batteries was significantly low. After a full charge, the blinking stopped.
Estimated Cost:
$0
Time Needed:
5-10 minutes
Steps:
- Turn off the golf cart.
- Use a multimeter set to DC voltage.
- Place the probes on the battery terminals.
- Check the voltage reading for each battery.
- If any battery shows low voltage, charge it immediately.
Expert Tip:
Regularly check your battery voltage, especially if you’ve been experiencing issues. A low battery can cause a multitude of problems, not just a blinking light.
2. Check the Solenoid
What I Did:
Listened carefully for a “click” sound from the solenoid when pressing the pedal.
Outcome:
The cart started moving again.
Personal Experience:
Initially, I didn’t hear any click from the solenoid. After replacing it, the cart was back in action.
Estimated Cost:
$0
Time Needed:
5-10 minutes
Steps:
- Turn off the golf cart.
- Locate the solenoid; it’s usually near the batteries.
- Press the pedal and listen for a “click” sound.
- If you don’t hear the click, consider replacing the solenoid.
Expert Tip:
If you’re not hearing the solenoid click, try tapping it lightly with a tool. Sometimes, a gentle tap can get a sticky solenoid to engage.
3. Check the Wiring
What I Did:
Inspected all wiring connections related to the controller and batteries.
Outcome:
The cart started functioning normally.
Personal Experience:
I found a loose connection near the controller. After tightening it, the cart worked perfectly.
Estimated Cost:
$0
Time Needed:
5-10 minutes
Steps:
- Turn off the golf cart.
- Inspect all wiring connections, especially around the controller and batteries.
- Look for any loose, corroded, or disconnected wires.
- Tighten all connections and replace any corroded wires.
Expert Tip:
Use a wire brush to clean corroded terminals. Corrosion can impede electrical flow and cause issues like blinking lights.
Safety info
- Controller Reset: Some Alltrax controllers have a reset button. If yours does, consider using it as a last resort.
- Software Update: Check the Alltrax website for any firmware updates for your specific controller model.
- Diagnostic Tools: Some advanced multimeters can check the health of your solenoid and even your controller. Consider investing in one if you’re a frequent cart user.
