Engine does not run but everything checks fint ?

Post by tfvinter » Jan 17 2022 3:01am

Hey all.
Suddenly my scooter will not run. Everything is checked and is fine.
Controller output is fine on the different wiers. Display is fine. Throttle handle work.
Measured 0.85 volt idle to 3.6 volts on full throttle signal.
Motor sensor all shows from 0 to 5 volts when turning the motor by hand.
Engine clicks somtimes but does not turn. I tried testing with the 3 facewire, hall sensor and throttle only connected to the controller.
The same result. Engine does not run. Tested with 3 different batteries with different volts.
So where should I look for the error? Thanks

Try another controller if you have one available. The only reason the motor would be the problem in this case is if it overheated and killed the Hall sensors or shorted the windings.

Also, closely inspect all the plugs and wires. Mysterious failure to run is usually a problem with the wiring.
This is to express my gratitude to Justin of Grin Technologies for his extraordinary measures to save this forum for the benefit of all.
