Slim Rack Slide Out Tester

I had a customer who stored his Motorhome in his garage. The slide out failed open and he couldn’t get the Motorhome out. He was trying for weeks and couldn’t find anyone that could get the slide out in. I took my other test box out there and was able to to get the slide out in. I knew for sure there was a damaged wire. I used a jumper to operate that motor and the other worked through the factory wiring. I knew I could come up with something that could make it easier and faster to move and diagnose a slim rack slide out. I made a video on how I made it and put up some wiring diagrams. I went through it pretty fast so if there is anything you want more details on let me know in the comments. I’ll also post chapters and affiliate links.
