Baffling slide/electrical issue

I need help diagnosing an electrical issue with my one of my slides and a fuse that keeps blowing. It started with my one of my slides not working (in which I became familiar with hand cranking it out for the first time) and at that time I had no blown fuse. I switched wires on the slide operating switch from the inoperable slide to the awning switch and it worked fine, so I assumed a bad switch. After a switch replacement proved not to be the problem, then the 15A fuse that supplies the operation panel starts blowing, and keeps blowing. So, where does this leave me? Slide issue or otherwise?

It sounds like you messed up wiring in the new switch (as others above have hinted)

Hard to know what applies, but I recently had to play with my slide not coming in properly and went through all sorts of things that might help here (or not).

First thing is you can be sure your motor and slide are ok, because it worked when you ran it off that awning switch.

You are now blowing fuses. I blew several (except I have a single big Lippert slide and it has spec for a 30a fuse.) The thing that blows the fuses is when the pos from the battery touches the ground (at the frame from the switch.) so the other thing is the switch has two wires on the slide side that must be joined then go to frame ground. Now the other thing is that the two wires that go to the motor change back and forth between being pos or neg for going in and out! (confused yet--too bad! everyone should have to suffer like I did! :) )

Now without a proper wiring diagram (which I didn't have because Lippert changed their wire colours since our 2003 trailer was built--(thanks a lot Lippert) you can easily get it to run in but not out or out but not in, and also for even more fun, you can get the pos from battery onto one of the two grounds on the slide side and blow the fuse one way or the other. It is hopeless unless you have a proper wiring diagram for the switch you have, whether new or old style switch--see Lippert website.

I also cleaned up the frame ground on mine but that wasn't really the problem, although the new switch does now run the slide in and out no problem. I was worried about paying $550 for a new motor, but it was all just the silly switch. It seems the switches get "tired " after a few years and don't pass enough battery juice along to the motor wires.
