It could be a circuit breaker. There are a 50 and 100 amp breakers in the pump compartment. The 50 amp is near the front, but the 100 amp is way in the back. You might have to move some cables to see it. Look hard its there.
Another 50 amp it in the left front of the engine compartment.
I had the 100 amp blow once. I argued with the Thor tech that there wasn't a 100 amp breaker in the pump compartment. I looked once more and moved some cables and there it was, the breaker was blown. After resetting it, life was good.
