My Spartan just stopped dead in the water. The rudder works, but no motor.
When power applied to the boat, the ESC flashes red, no sounds, the rudder works and the motor will "pulse"; that is the motor will move just a few millimeters, stop then do it again. Sometimes when power is applied this motor pulsing does not happen. All batteries have been changed and I'm sure this is not battery related.
I'm trying to determine if the problem is the ESC or the motor. There are 3 wires going to the motor, can I apply voltage to any of these to see if the motor actually runs? If I plug a multimeter into any of the 3 outputs of the ESC, can I expect to see anything; thus checking the ESC?
