So in my 2006 silvercreek caravan the slide out motor stopped getting power to it about 5 years ago so for the last 5 years I have been using jumper cables to connect the motor to the battery to power it red and black for going out and just black for going in. Now last week I thought I would have a look at the issue it turns out the positive and negative cable to the motor were corroded so I replaced them now it works but only going out. The positive and negative cables both work so I don't know I tried the jumper cables and it works fine could you help me please?
From your original post it seems there is nothing wrong with the motor, since you said you were able to operate it by connecting wires manually.
You have now rewired it and it fails to retract the slide outs.
Logically it means you have done something wrong in the rewire or as someone else suggested you have a problem with the controller itself I.e it is not giving the command to the motor to go in reverse.
Auto electrical needed to trace.
maybe time you had it seen to by people that deal with american units, if you wish i can give you some contacts, 2 of them allow you to stay with your van while they do the work required. I hope the transformer you were on about in your other post is not a yellow box one, but proper units which are grey If you would like me to post contacts for you let me know on here
I take it your slide works on a cable pully system to motor rather than hydrolic rams
