I have a 21' open car trailer with a 12v truck battery on it used to power the 9000lbs winch. i spoke w/ a mechanic from my local chevy dealership and he had stated that there was an open spot in my fuse box to put a 30 amp fuse to charge the battery thru the factory trailer wiring harness and plug. i havent put the fuse in yet. my question is by putting that fuse in does it charge the trailer battery(trailer,plug,and battery is wired correctly) is the mechanic correct or will i have to do something different?
