Golf carts frequently become damaged because of overuse, improper use or a lack of maintenance. The latter often results in dead batteries, which can be fixed rather simply. A few other common problems include flat tires, bent or broken rims and body damage.
Replace the battery on the golf cart if the cart does not start. Since nearly all golf carts are electric, the battery often runs down and when empty the cart will not function at all. Remove the battery by disconnecting the cables to the battery terminals. Wearing gloves, remove the battery and replace it with a fresh one. Immediately recharge the old battery by hooking it up to a battery charger.
Check the battery terminals. If the cart still does not function with a fresh battery installed (one you are certain is fully charged), remove the battery cables and clean them by brushing with a wire brush. Inspect the battery case for leaks, cracks or damage. If the casing is cracked, a fresh battery needs to be installed.
Inspect the tires on the golf cart. They should be fully inflated and there should be no sags around the bottom of the tires. Each tire will indicate the air pressure rating on the rim. Using an air pump, inflate each tire to this proper pressure. This can correct problems with the steering like constant swerving to one side.
To fix a flat tire, first attempt to inflate the tire with an electric air pump. Listen for hissing sounds (air being released) and see if the tire remains inflated. If not, jack up the golf cart on a car jack. Remove the lug nuts that secure the tire to the axle and remove the entire wheel rim and tire. Replace the complete wheel rim and tire with a new one.
Accelerator issues are another common golf cart problem. To fix an accelerator issue, inspect the accelerator pad. On EZGO golf carts these include a lever mechanism. Using a matching socket wrench, tighten the bolts which secure the pad lever to the accelerator rod. Inspect the lever mechanism to ensure it is not stuck. Apply grease, or remove the pad by loosening the attaching screw at the base. Sand away rust and clean, then paint the pad with automotive grade spray paint and replace the pad.
