So i am an ebike tech at pedego in nanaimo bc im working on a bike that previously had capacitors fail in the motor controller. Im not that familiar with motor controllers but am wondering if their are any known symptoms like shorted phase wires or stalled motors that cause capicitors to fail.

Being a bike tec think you would appreciate this awesome wright up on motor testing
