I picked up a used st plow for my 01' Jeep cherokee sport. I got it all mounted to find out the receiver is bad. I had a plow shop run tests on it and they found that all the coils have power to them when you turn it on with the controller. The only funcation it has is down, then I need to jumper around to different coils to get it back up. As anyone installed roller rocker switch to work around this problem. New receiver cost $350.00 any help would I be greatful.
