2004 Silverado with factory tow package, 7-pin connector. The 12v pin is not supplying any power. I'm pretty sure it worked before, charging up my trailer battery. All other pins work fine. I imagine it's protected by a fuse, so that's what I'd check first. But none of the fuse descriptions in the manual or in the fuse boxes seem to apply. I've pulled all the high-amp fuses and all look good. Is there such a fuse? If not, what else should I check? The connector into the "fuse box" (really a connector box) under the steering column seems tight. If I knew which lead should be hot, I could check for 12v there. Any other connectors along the route to the bumper that I should check? Thanks.

Replying to: rsworden (Feb 04, 2007 2:22 pm) So it had never worked before - we have always charged the trailer batteries from house power before our weekend trips, and on longer trips we have had 120v in the campgrounds, so we never noticed that it was not charging up while driving.

Replying to: rsworden (Feb 04, 2007 2:22 pm) To power up the pin in the trailer connector (for trailer battery charging) you MUST intall a maxifuse in Stud #1 slot in the underhood fuse center. There should be a plastic plug already in place which you will have to remove and insert a maxifuse.................... |
