Re: no negative from contoller 2007 "the drive"
If tow/run switch is powered & good, battery voltage not too low (below 45v), no click ( negative to contactor) when switching to "run" = Bad controller.

Might also check for a broken black wire at speed sensor.

Nope, 0-5v. And sensor cannot be checked with ohm meter, volts only.

Re: no negative from contoller 2007 "the drive"
Non contact potentiometer. Inside the sensor lives a Hall-effect sensor, and a magnet that rotates nearer or farther from the sensor as the pedal rotates. At rest signal will be around 0.4v, full throttle will be around 4.8v.

Re: no negative from contoller 2007 "the drive"
if this item is bad could it cause a no negative voltage out from controller (pin3)
(my current problem) I want to eliminate as much as possible before buying new controller...... |
