Following is a picture of a fuse box next to the primary fuse box in my 1989 560 SEC.
Anyone know what this fuse box controls? The lower fuse was missing this morning when I looked at it trying to find why my radio was blowing it's fuse.

Should these fuses be blue?



Then I found this resistor that was smelling of burning and I think it has something to do with the radio circuitry. The arrow points to the radio fuse. The only thing on was the radio for a short period of time and then the fuse blew, tried it again several time with the same result. Also the Antennae will only go up part way. I did try the radio with the Antennae unplugged to see if it was the antennae that was causing the fuse to blow. It wasn't.
I believe the bad resistor(I didn't get the number off it though) is the culprit.
Radio is good and I have the code and it played for a few minutes before the fuse blew the first time. Afterward the fuse blew immediately.
Yes, the fuses will all be changed out to copper ones shortly.
