That same fuse blows on my 20 MRB when the slide is extended. Dealer claimed it was due to dirty battery terminals. I don't think so.
I have purchased a 30 amp circuit breaker from an online electronics warehouse in Reno. It is the kind, that if it trips, it will reset it self. Once I get it installed, I will post here on the JOF how well it works, or not.
