What's Wrong With My Golf Cart?
Answer a few questions about your cart and what it is doing. We’ll narrow the problem to the systems most likely to need testing.
Common Golf Cart Problems by Symptom
The diagnostic tool above is designed to narrow the problem based on what the cart actually does. These guides explain the major systems that are commonly tested for each symptom.
Golf Cart Won't Turn On
A golf cart that is completely dead may have a discharged battery pack, blown main fuse, loose battery connection, failed key or run circuit, contactor problem, or a lithium battery management system that has entered protection mode. The correct test sequence starts with battery voltage and main power distribution before individual parts are replaced.
Run the diagnosticGolf Cart Turns On But Won't Move
If the dash, lights or accessories work but the cart will not drive, the problem can involve the accelerator input, solenoid or contactor, motor controller, forward/reverse circuit, motor wiring or the motor itself. Whether the cart clicks, jerks, shows an error or moves in only one direction helps narrow the test path.
Run the diagnosticGolf Cart Won't Charge
Charging problems can come from the wall outlet, charger, charge receptacle, battery pack, battery connections or a lithium BMS. A charger that does nothing requires a different diagnostic path than a charger that starts and stops, reports full too quickly or appears to run normally while the batteries remain low.
Run the diagnosticGolf Cart Has Low Range
Reduced driving range is commonly related to battery capacity, weak individual batteries, incomplete charging, high-resistance connections or excessive mechanical load. Terrain, passengers, tire pressure, speed and cart configuration also affect range, so battery testing under load is more useful than replacing batteries based only on age.
Run the diagnosticGolf Cart Loses Power or Shuts Off
A cart that shuts off while accelerating, climbing hills or after driving for a while may be experiencing battery voltage sag, a loose high-current connection, controller thermal protection, motor overheating or lithium BMS cutoff. How the cart recovers after the shutdown is often one of the most useful clues.
Run the diagnosticGolf Cart Clicks But Won't Move
A click confirms that at least part of the control circuit is responding, but it does not prove the solenoid is good or bad. Battery voltage under load, high-current cable resistance, contactor output, controller input and output, and motor condition may all need to be checked before a part is condemned.
Run the diagnosticGolf Cart Runs Slow
Slow acceleration or reduced top speed can be caused by low battery voltage, reduced battery capacity, high-resistance cables, controller limiting, motor problems, accelerator input issues or mechanical drag from brakes and wheel components. Comparing performance at full charge and under load helps separate battery problems from drivetrain problems.
Run the diagnosticGas Golf Cart Won't Start
Gas golf carts can fail to start because of battery or starter-generator problems, safety switches, ignition faults, fuel delivery, carburetor issues or compression. Whether the engine cranks, whether choke changes the symptom and whether the problem occurs hot or cold helps determine what should be tested first.
Run the diagnosticGas Golf Cart Backfires or Runs Rough
Backfiring and rough running can involve fuel mixture, carburetor condition, ignition, valve adjustment, intake leaks or stale fuel. The point at which the backfire occurs—during acceleration, deceleration, startup or shutdown—can significantly change the likely cause.
Run the diagnosticGolf Cart Brake, Steering and Suspension Problems
Pulling, wandering, wheel wobble, brake drag, grinding, clunking and uneven tire wear can point to brake adjustment, steering linkage, alignment, wheel bearings, tires or suspension components. Severe brake loss, wheel looseness or unstable steering should be inspected before the cart is driven further.
Run the diagnosticGolf Cart Brands We Commonly Diagnose
The tool can be used for Club Car, E-Z-GO, Yamaha, ICON, Evolution, Tomberlin, Advanced EV, Bintelli, STAR EV and other electric or gas golf carts. Exact components and test procedures vary by model, year, voltage and power system.
