Took coach into RV Body shop to have couple of minor issues fixed. while there they advised they do all RV service work. Told them light over computer not working they advised dead short and took apart and fixed.
Went to pick up camera and radio dead. Left they called an said major fuse from batteries to coach blew (300 amp fuse)
Picked up today fuse replaced, drove 1 hour to camp, all batteries dead, bulk charging, NO HOUSE LIGHTS, few stair and refrigerator lights working,
In the dark
Checked all breakers in closet, nothing, is there main fuse that controls house lights ?
