2002 Excursion 7.3 PSD Electrical Issues
I'm new to this forum and hope someone can help. Here is a list of things that suddenly quit working. Interior lights, windows, radio, and gauges. About a week ago I had a similar problem and it was the PCM fuse. I checked that fuse and its fine. I unhooked the battery for 30 min and didn't help. Swapped some of the relays and still no help. Any help would be greatly appreciated.

Well the good news is that there is going to be a common problem, bad news is that it might be an alternator, might be a CCRM, might even be a bad ground. Electrical gremlins are the WORST... I spent months chasing down one in my old Cobra that wound up being a $30 part...
I'd start with getting the alternator tested, if it tests good you've eliminated that and move on to the next thing. Good luck with it.

Here is a thread about similar stuff. People have all kinds of ideas on the fix and all seem to be a little different. Some reading for you anyhow.
