    Electric throttle is not working on the spreader . Have power back to motor . How does it pick up ground ? Need to test to see if it's ground or motor . Thanks

    There is no conventional ground. Current flows both ways depending on the direction you want the throttle to move, Best way to test the throttle control is to disconnect the wires and use a 9 volt battery. Touch the red and brown wires on the control to the terminals on the battery and the crank arm should move in one direction - reverse the polarity and it should move the other way. I recently had an issue with mine and found a broken wire inside the housing which i was able to fix (thank god cause they're pricey little buggers - $200 +).

    Thanks Buster . I took the motor apart today , lots of corrosion on the terminals . Cleaned things up and got it to work . BTW it wouldn't work with the 9v but did on 12v . Can't believe the price they want for those , could not have cost more than 2 bucks to produce .

    I couldn't agree more - these trottle controls are one of the worst cases of sticking it to the consumer i have seen in a while. Glad you got it fixed, B
