I disconnected my motor from the Curtis controller. I fed the HV lugs of the controller with 12 volts from the accessory battery.
The motor connection saw about 10 or 11 volts even with the throttle at zero and when I move the throttle all the way up the voltage was about the same. I think this means that my Curtis controller is shorted open but if anybody could confirm if this test is valid or not at 12 volts with no load other than a multi meter that would be appreciated.
