I am new to RVing, and this is my first post. Thanks for letting me join. I am a do it yourselfer so I am hoping to find some help. I have just purchased my first RV. It's a 2001 Timberline Timberlodge 27BHS trailer. The slide out doesn't work. I have a good battery on board, fuses are good, I have 12V to the controller. I have tried direct 12V to the motor & the motor activated & tried to move the slide in (which it already was). I reversed the wires to slide out but all I got was a spark, no movement. The controller and switch are no longer available. My question is..... Can I install a different controller and switch to operate this 12V motor?
