radio not working
my radio stopped working while fixing other wiring issues on my truck. my earlier thread explains those:
https://www.ford-trucks.com/forums/1...ch-issues.html
it worked just fine before all that in previous thread, now it doesn't have any power to it at all. I checked the fuse, pulled the radio back out to check for connectivity and examine the wiring. all looks as it should. also the headlight **** lost it's ability to turn on the courtesy lights, headlights work when pulled, but turning **** all the way doesn't turn on dome anymore, which isn't a big deal to me, only mentioned it in case it's somehow related.

oh, and my headlight **** does turn on the dome light, I don't know what I was thinking earlier, or if it didn't work earlier it does now.

The radios ground through the cases. Disconnect the harness from the radio and put a volt
meter on it and see if you get voltage on the yellow/black-hash wire with the ignition in
RUN or ACC.
My guess is a bad ground from the case to the dash support frame.

Does the truck have the Engine to firewall ground in the engine compartment by any chance? This can cause all sorts of weird grounding issues if it's not connecting very well or if its missing.
The main dash ground, grounds where it bolts to the side of the cab. If the metal is rusty you may need to add a ground wire from the dash metal support to the firewall.
There is also a ground wire that attaches to the dash metal frame, to the right of where the radio rear mount, mounts to the dash. Make sure that ground is clean and tight also, as it's a major ground for a lot of componets.

fixed
per ctubutis's advice, I checked the yellow/black dashed wire for power, and discovered it had slid out of the harness. I couldn't see the wiring to the radio on the wiring diagram, so I had no idea what I needed to look for. Thank you ctubutis, while radio isn't a necessity, it sure makes driving more enjoyable.

I did check those while I had it all apart, was so excited when I fixed the issue, guess I forgot to mention that part of it. Thanks for the suggestion, I did brush a little surface rust away and made sure everything was tight.
