Question:
On my 7 way connector, the 12v , 1 oclock position, has a red wire to the 7 way, but there is no power at the terminal. Is there a fuse I need to check?

Expert Reply:
Yes. Check Fuse #90 in your fuse block. It is a 25 Amp cartridge fuse for trailer tow battery charge located in the engine compartment. You can find the location in your owners manual if you need further location help. I've also attached a help article on wiring to help with further troubleshooting if needed.
If the fuse isn't blown, you will need to use a circuit tester like # PTW2993 to check for a short in the wire and replace the wire as needed with # 10-1-1 sold by the foot.
