All brands of electric golf carts, including E-Z-GO, will eventually experience minor to major electrical problems as a result of normal wear and tear. Common problems experienced by cart owners range from the golf cart not starting to the cart losing speed when going uphill. Before spending money on a mechanic, see if you can repair the problem yourself. This guide covers some common troubleshooting tips to pinpoint your cart's electrical problems.
Difficulty: Moderately Easy
Verify that your lights and all other golf cart peripheries such as a built-in GPS or radio were turned off after the cart's last use. If they were not, and your cart will not start, then you will need to recharge your cart's batteries.
Don acid-resistant work gloves and open your golf cart's battery compartment. If your cart is experiencing loss of power, or inconsistent power availability, your battery connections may be loose, frayed or corroded. Visually inspect each connection. If any appear significantly frayed or broken, you will need to replace the battery cable. If they look intact, twist each battery connection back and forth to test for tightness.
Visually inspect the battery terminals and connections for significant indications of corrosion. Corrosion can result in sporadic power loss while operating your golf cart as well as loss of power when traveling uphill. If there is a large amount of corrosion present, attempt to remove the corrosion using a rag lightly dipped in mineral water. In severe cases of corrosion, replace the battery connectors with new ones.
Find the ignition wire on your golf cart by tracing the golf cart key assembly to the cart's starter. Most E-Z-GO golf cart ignition wires plug into the solenoid (a cylindrical coil of wire) and can become dislodged when the cart is operated on heavy terrain. If the wire is loose, reseat it in the solenoid. If the wire is frayed or corroded, consider replacing it.
Verify that your golf cart transmission is fully in the "Park" position when not being operated. Some electrical issues found in E-Z-GO golf carts arise from the transmission selector switch not being placed fully in the correct position for the desired means of transportation.
