Repair Handbook: Troubleshooting Roundup for Electrical System of Electric Tricycle-7

7、 The tricycle runs once powered on, with fast acceleration (known as “sharp speeding”).

(1) Causes:

① Throttle damaged or cathode wire (black) open circuit or poor connectors, ② Controller  malfunctioning

(2) Troubleshooting:

① Disconnect the throttle. If it is normal, the controller is normal, and the throttle and cathode wire should be checked. If the tricycle does not stop after disconnecting the throttle, the controller is damaged and should be replaced. 

Tips: Check the cathode wire of the throttle.
