Electrical Problem - Help!

[Saskatooner]

We recently purchased a 2012 321RLTS. Plan to head out on first trip this weekend. For some reason the reverse polarity (25 amp) fuse keeps blowing. It blew a few weeks ago but I replaced it and it was fine for a while.

I switched all the breakers off and replaced the fuse. When I switch the Leg 1, Leg 2 breaker on the fuse blows.

I am connected to house power. Only one (of two) blue lights are llit up on the 50 amp cord.

Any ideas?

Dealer time. My rig had those fuses blown when I got home and I replaced them with Slo Blow fuses of the same size. That may not fix your problem, but there is sure something wrong.

Im plugged into house power with 2 adapters to go from 15 amps to the 50 amps and both blue lights are on.
