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.
