Check the circuit breaker in the main wire from the cutoff switch. Jack and slide have their own inline fuses and are wired to the hot side of cutoff switch as a rule. Rest of trailer get's it's power from a resettable circuit breaker that is somewhat hidden. Follow hot wire from battery(s) to cutoff switch and from the switch follow it along to a small box with two wire studs on it. On the side will be a small "bump" that when pushed will reset the breaker.
After reset you should be good to go.
