To get power to the motor I have to squeeze the front brake

I’m reading this two ways;

1) You either mean that when you pull the brake lever, the motor runs.

2) OR when you pull the brake lever, then the throttle will work to run the motor.

If the first case, then there may have been water intrusion somewhere. Probably at the controller location since that is a common location that those wires would meet.

Follow up question to the second case….What happens when you only pull the rear brake lever?

Cool. For verification, if you have a 2 conductor sensor, you can meter into the brake sensor and see what the issue is. Most brake sensors seem to be Normal Open. With a meter, you’ll see a short when the lever is pulled. Should be open otherwise.

I’m not sure how 3 conductor brake sensors work, so I have no suggestions there.
