Re: (ET) Winch motor wiring



Red is UP, Yellow is Down, Blue is common. If Red and Yellow are reversed, it is no big deal, just run the lift strap out all the way, by using whichever direction will play the strap out, then hold the switch in the Up position.

      YELLOW             |             |  RED
                                   |              |

                                     ______
                                       BLUE


As far as high current draw in one direction only, suspect mechanical binding in the lift itself, or a shorted field winding.

Quick questions:

1) What is the pin-out of the winch motors? IE: Is the back one the common, and the two side ones up and down?

2) When I use the back as a common, the motor runs very well in one direction, and very poorly (draws a *LOT* of current) in the other. Any reason in particular why this would happen?

Thanks!
Chris
