RV Repair: RV electric slide out (04 trailbay), electric slide, circuit breaker

Question
The inside switch doesn't operate the slide out. I hooked a new battery to the motor and the slide worked. I hooked the battery up to the trailer and got nothing at the switch. is there a fuse or a relay that could be bad???

Answer
Yes there is usually a circuit breaker for the 12 volt slide near the batteries somewhere. They will have 2 posts with wires going to both sides. Check power to see that it flows from one side to the other and the one that doesn't is bad. They are usually 30 amp or bigger sometimes.
