What amp fuse for charging circuit from truck Alt?

I have a new (to me) 2006 Chevy 2500 and a camper to go with it. This truck has a factory tow package but the red wire "battery feed" on the factory plug at the bumper is dead, even with the truck run...

Hi,

I would encourage you to use a continuous duty relay rather than the (expensive) "smart" isolator.

I replaced the 60 amp fuse with a 50 amp automatic circuit breaker.
