This just started on a 3 year old motor. It trips GFCI on start up. I hooked it to a non GFCI and it works OK. I pup my clamp on it and there is a short 200ma spike right when it starts. I know the short answer is the motor is bad, get a new one but does anyone have any other ideas?
This is a boat lift so running without GFCI protection is a "you bet your life" thing.
Although tripping the GFCI is not the most common effect of a capacitor fault, and your motor does work without GFCI, there are still some defects that can make a capacitor trip the GFCI (assumes you've ruled out the most common culprits for the problem).
