My golf cart fuse blows and shuts off when pedal is pressed

For some weird reason, my EZGO TXT golf cart has suddenly decided to throw a tantrum. Every time I press the pedal, hoping for a smooth ride, the fuse blows, and the cart just stops dead in its tracks. It’s incredibly frustrating, especially since I rely on it daily for getting around my large yard. Has anyone else faced this issue? How did you manage to fix it?


Oh yes, I ran into this too with my cart a while back. Turned out to be a pesky faulty relay hiding next to the big plug/controller. Swapped it out with a new one from AutoZone, and just like that, the problem was history. The cart wouldn’t ignite properly before, and changing the relay was the fix it needed. Wasn’t too hard on the wallet or time either. Hopefully, this gets your golf cart moving again!

1. Replace Faulty Relay

Detailed Steps:

  1. Identify the Relay: First off, you need to locate the relay. It’s usually situated next to the big plug/controller, often in the area over the rear passenger wheel well. If you’re unsure, refer to your cart’s manual for the exact location.
  2. Acquire a Replacement: Head over to an auto parts store like AutoZone and look for a relay that matches the one you’re replacing. Ensure the specifications (voltage, amperage, pin layout) align with your original part to avoid compatibility issues.
  3. Swap Out the Relay: Using basic hand tools (screwdrivers, pliers, maybe a socket set), remove the faulty relay and install the new one. Make sure all connections are secure and that the relay sits firmly in its designated spot.

Handy Tips:

  • Visual Inspection: Before purchasing a new relay, visually inspect the old one for any obvious signs of damage or wear. Sometimes, the issue can be as simple as a loose wire or corroded terminal.
  • Test Before You Ride: After replacing the relay, test the cart in a safe area before heading out. This ensures everything is working as it should.

Expert Insight:

Relays are critical for directing power in your cart’s electrical system. A faulty relay can interrupt the power flow, leading to issues like the fuse blowing when you press the pedal. Regular checks and maintenance can prevent such problems.

2. Check and Replace Voltage Regulator (if faulty)

Detailed Steps:

  1. Locate the Voltage Regulator: The voltage regulator’s location can vary between models but is generally found near the battery compartment or engine. Your cart’s service manual will have this information.
  2. Diagnostic Test: Disconnect the voltage regulator and attempt to use the cart. If the fuse remains intact and the cart operates, the regulator could be the issue.
  3. Replacement Process: If the regulator is deemed faulty, purchase a compatible replacement. Disconnect the battery before removing the old regulator to avoid any electrical mishaps. Install the new regulator, ensuring all connections are tight and correctly positioned.

Handy Tips:

  • Battery Health: Before blaming the voltage regulator, check your battery’s health with a multimeter. A failing battery can sometimes cause similar issues.
  • Keep It Clean: Ensure the area around the voltage regulator is clean and free from debris. Excessive dirt or moisture can lead to electrical failures.

Expert Insight:

The voltage regulator plays a pivotal role in managing your cart’s electrical system, ensuring the battery receives the right amount of charge. An overcharging or undercharging battery due to a faulty regulator can lead to various electrical issues, including the frequent blowing of fuses.
