Once you identify a faulty connection, securely reattach the wiring or replace it. For a bad sensor, you’ll generally need to replace it to restore proper accelerator function.
Golf Cart Hesitates When Accelerating
Understanding Hesitation
Hesitation is when your golf cart momentarily falters as you press the accelerator before it actually accelerates. This can be due to a delay in response from the motor controller or a lag in battery output.
Throttle Response Testing
You can test the throttle response with a multimeter to see if the throttle sensor is sending the correct signals to the controller. Any delay may indicate a sensor issue.
Battery and Voltage Analysis
Perform a check on your batteries and their voltage levels. If the batteries are showing significant wear or are not holding a charge, this could be your hesitation’s root cause.
Dealing with Motor Controller Problems
If the battery and throttle tests return no issues, the problem might be within the motor controller. Inspect this component for any error codes or obvious damage.
Tips for Smoother Acceleration
To achieve smoother acceleration, ensure that all electrical connections are clean and secure, batteries are in good health, and no components are overheating.
Sticky or Stuck Accelerator Pedal

Maintaining Pedal Mechanism
Regular maintenance, such as cleaning and lubrication, will keep your pedal mechanism in top shape and prevent future sticking issues.
Low Top Speed
Distinguishing Low Speed Symptoms
Low top speed means your golf cart doesn’t accelerate to its potential maximum speed. This may become apparent over time or following a specific incident.
Evaluating Motor Performance
Check the performance of your golf cart’s motor by listening for any unusual sounds and inspecting for signs of wear or overheating that might indicate its efficiency is compromised.
Battery Testing for Sustained Power
Evaluate your batteries under load to ensure they are providing sustained power. Batteries nearing the end of their life may not hold enough charge for maximum speed.
Speed Controller Adjustment
If your motor and batteries are working properly, turn your attention to the speed controller. It may need adjustment to allow for higher speeds.
