Hey I just noted that this post did not get a reply. I am guessing everyone just not sure what it meant by "switch trips"? On my Journey, I can guarantee a fault code at my slide switches if I operate the slides without my engine running. The slides on my coach will operate without the engine running but my coach has two half coach length slides on the drivers side. Those slides are heavy and they put quite a draw on my batteries. As soon as my voltage drops below a certain point, I will get a fault code blinking on my switch which I usually have to manually reset. Sooooo, I quite running my slides without my engine running and I have not had a problem (knock on wood).
