Troubleshooting and Repairing Electric Scooter Controller Issues

What is the speed controller?

The speed controller is a component on an electric scooter that keeps the scooter within a set speed range for both safety and compliance reasons. It lessens the need for effort on the part of the driver as well as reduces the chance of human error, but it’s a delicate electronic component that is somewhat prone to damage. If your scooter is malfunctioning, the controller is one of the first things you should check on. This DIY will save you money on repairs, which is one of the great benefits of electric scooters. Don’t forget that you should know where the ID number on your electric scooter is in case you need to buy a replacement part.

Troubleshooting and Repairing the Controller

1. Switch on the scooter in order to get power to the controller to properly test it. If it’s still running at all, try riding a short distance in a safe area at a slow speed so that you can A/B performance and functionality after you’ve troubleshot the controller and made any necessary repairs or component replacements.
2. Start by looking at the external electric wiring of the speed controller. Look at the circuit breaker, fuse, and switch for any obvious damage and check for any unusual fumes are smells coming from the controller and the rest of the scooter, which may indicate fire damage.
3. Once you’ve determined which part of the speed controller is damaged or having issues, turn off the scooter and dismantle the controller using a small Phillips head screwdriver. Loose wires should be tightened and broken wires replaced, and if a fuse or circuit breaker has burnt out, you can replace them with matching components.
4. Once any internal issues with the speed controller have been dealt with, carefully reassemble it. Care is recommended here as it is a common step to make mistakes- make sure wires are securely connected and all screws are tightened fully. You can then reattach the controller, ensuring the connections are correct and securely attached.
5. Turn the scooter back on and try driving it a short distance to see if the problems you experienced persist. Keep in mind that problems with your scooter can occur from a combination of malfunctioning components, but dealing with damaged controller parts is always a good idea, regardless.
