I used my multimeter to determine that no voltage is going to the 12+/charging pin on my factory-installed 7-pin RV bumper-mounted connector. I downloaded/printed the layouts and fuse numbers/functions on both my passenger compartment fuse box and engine compartment fuse box. Quite a lot of fuses...

Before I start pulling/inspecting assumed blown fuses that might go to this particular pin, which fuse(s) correspond(s) with this pin?

Thanks,
Thom

Check the battery junction box under the hood for the trailer tow battery charge relay and F21. My truck came with both of those items in a bag in the glovebox when I bought it new. If you are not the original owner the previous owner may have never installed them.

 

well first thing to look at is the 7 pin socket. They separate into two pieces. Mine had the green starting in the terminals just had to clean both pieces. I went ahead and changed the plug. The o- ring between the half's needs jelly to help put back together. Bet its this area.

 

Thanks for both suggestions. Been very busy but plan to try both next week and then get back to you. I'm the original owner.
