It is not a fuse but a resettable circuit breaker. It is located in the front compartment where the pump is located. There should a strip of them. There should be a large red cable coming from the pump to the circuit breaker. Check the breaker and if it is a 50amp, then it needs to be replaced with an 80amp one. The problem is that you will have to actually mount the 80amp breaker on the wall as it will not be the same size as the 50amp. If I can find a picture of the end result I will post it. There was a set of pictures on the old forum, but I don't know who to locate them.
Just to be sure, the rig levels without problem. It is only when retracting that I have a problem, and it only started toward the end of last summer. Does this sound the same as the issue you were dealing with? Does the fuse automatically reset? I have not reset mune when it stops retracting. I just wait 10-15 seconds and then press the retract button again.
I think it is similar. The existing circuit breaker is an automatic resetting one and it takes a short time, maybe 10-15 seconds, to reset which is what the 80amp breaker resolves. As long at the breaker is resetting, and you are OK with the time lag, and starting over, I would leave it alone. In my case it was doing it anytime I used the system. It became a pain.
