Hi guys.
1990 S/C 5-speed.
I'm trying to restore all my S/Cs functions and I discovered I was missing a fuse, which was the courtesy light fuse/fuse for all non-ignition power sources. Basically, all the stuff will work just fine-- only when the keys are in the ignition.
So, I put in a new 10a fuse. The lights come on for a second and then POP the fuse goes. So I put in one more. Pop yet again. When I got the car, however, that fuse did not pop immediately when I put a fuse in it. It actually worked when I left it in, but I was afraid it would drain my battery. Since I've figured out otherwise since then I've found that there is a short somewhere that is occuring in the non-ignition power circuit-- you know, the standby power for your courtesy lights, keyless entry and all that crap.
All the stuff that works fine and isn't blowing fuses when you use it-- overhead lights, doors etc all works, except when the key isn't in the ignition.
The other thing is, when I bought the car, it had a functional cd player. The CD player will no longer power on when hooked up in the car. So far as I can tell everything is there, but I just can't seem to find what the hell is shorting because every wire I find that isn't connected to anything is promptly capped and wrapped in electrical tape if I don't know what it goes to. How would I test and hunt down whatever's causing the lack of juice to the player.
It's not a fuse since all fuses and fusible links are just fine outside of the courtesy light fuse, and the VMM above it still comes on just fine, and my ac controls all work -- only the radio is out. I yanked the thing out and went through its harness and found two loose wires that needed to be taped up, but after that everything appeared to be intact if not a little messy.
Any ideas on where to check, what could be causing the short etc etc.
Any input is much appreciated!
Thanks very much,

Where would I look for a short, and how would I test for it?
