Is there truly a fuse as shown in the users guide somewhere between the truck power socket and the rv batteries? If so where is it located and what does it look like ? However all the lights work and trailer brakes work. Tomorrow I'm going into the junction box and checking for continnuity in the umbilical cord.
Thanks for any help
I don’t know where that rv fuse would be located either, but then again I’ve never had a reason to look for it.
I’m assuming your truck isn’t charging your rv batteries. On my Ford, this is the one problem that off and on surfaces. When I got the truck, the fuse for the charging circuit was in the glove box. The truck charges the batteries ok but every now and then while towing, I get a dash warning to “Check Charging Circuit”. I’ve had my Ford dealership run a diagnostic twice but they can’t find a problem. I will let them check it again when I take it in in March.
So my comment would be to check your truck to rv charging circuit on your truck for a blown fuse. Once again, I’m only assuming Chevy has a fused circuit.
