Why does my golf cart charger click but not charge?

A clicking sound indicates the AC relay is engaging, which is good. If the charger does not output amps after the click, the issue is typically a blown DC fuse (in the receptacle or charger case), a broken DC cord, or the battery voltage is too low for the charger to detect.

Where is the fuse on my golf cart charger?

On EZGO TXT and RXV models, the fuse is located behind a small plastic cover directly on the charging receptacle where you plug the cord in. On Club Car models, it is often an inline fuse on the grey wire behind the dash, or located internally inside the metal charger housing.

How do I fix a charger that clicks on and off repeatedly?

Rapid clicking usually means the battery voltage is too low for the charger to stay engaged. The charger turns on, fails to sense a healthy battery pack (safety cutoff), and turns off. You must manually charge the batteries individually with a 12V automotive charger to raise the voltage above the minimum threshold.

Charger Clicks But Won’t Charge

You hear the reassuring “click,” but the next morning the cart is dead. We diagnose the “Open Loop” failure in the DC charging circuit.

A “Click” only tells half the story. It means the AC wall power is working. If the ammeter stays at 0, the DC side has a roadblock—usually a $2 fuse.

01 // The Pathway of Power

To fix this, visualize the path. Electricity travels: Transformer -> Rectifier -> Internal Fuse -> DC Cord -> Receptacle Fuse -> Battery. If any link breaks, you get a click but no charge.

02 // Culprit #1: Receptacle Fuse

Most modern EZGO and Club Car Precedents hide a safety fuse right where you plug the charger in.

EZGO TXT/RXV

Look for a small plastic cover on the face of the receptacle labeled “FUSE.” Pry it open to reveal a clear glass 60-Amp fuse.

Club Car Precedent

The fuse is inline on the Grey Wire coming off the back of the receptacle (yellow rubber fuse holder).

Critical Spec

Use only a 60A Slow-Blow fuse. A standard automotive fuse will blow instantly upon connection.

03 // Culprit #2: Internal Charger Fuse

If the receptacle fuse is good, the problem is inside the box. Warning: Unplug from wall and cart before opening. Capacitors hold lethal charge.

Location: Near the thick DC output wires. Often a white ceramic fuse or copper strip.
The Test: Set Multimeter to Continuity (Beep). Touch probes to both ends. No beep = Blown.

04 // Culprit #3: “Too Dead to Charge”

Automatic chargers need to sense ~32-36 Volts to turn on. If your cart sat for 3 months and dropped to 20V, the charger thinks it is not plugged in.

The Fix: Use a 12V automotive charger to charge each battery individually for 30 minutes. This raises total pack voltage enough to wake up the golf cart charger.

05 // The Decision Matrix

How to identify the failure without opening the box.

Symptom	Probable Cause	The Fix
No Click	AC Power / OBC	Check Wall Outlet
Loud Click, 0 Amps	Blown Fuse	Replace DC Fuse
Loud Hum, 0 Amps	Bad Capacitor	Check Rectifier
Rapid Clicking	Low Voltage	Manual Charge

06 // Testing the DC Cord

Wires often break internally inside the rubber handle due to stress.

Continuity Test: Touch one probe to the Positive pin on the handle, and the other to the Positive wire inside the case.
Wiggle Test: Wiggle the handle while testing. If the beep stops and starts, the wire is broken internally.

Summary Checklist

Check the Receptacle Fuse first (Easiest fix).
Verify Battery Voltage (Must be >30V).
Inspect the Handle (Wiggle test).
Listen to the Hum (Hum = Transformer OK).

Verified Fix: Restore DC Path

Most “Click No Charge” issues are resolved by replacing the 60A receptacle fuse or manually charging dead batteries to restore sensing voltage.
