2000 Carver 356 breaker for battery charger.

[cpoint]

Viper, yes ProNautic P is what I have. I had a marine electrician check out before, he said hookup was fine, battery was charging properly and all 3 ports on charger were live. Unfortunately, this was before I realized the switch settings, and I believe the switch was on BOTH at the time, so all looks fine at that point when you take readings. So, after eliminating all based on that and what has been written here and in previous post, I feel it is either wiring came loose maybe first time I attempted to open the fuse box, or damaged fuse (as pictured). And you are correct access is troublesome. I did not think about trying to access from aft cabin. Maybe I can try that, but I am sure not going to be too useful. Next time I am out there I will try again to see if i can open it up. Wish they had left some extra wiring in there for easy access
