Dear Experts-

I have a 1990 560 SEL and the fuse box no longer has a diagram for fuse locations. The radio no longer works but constantly stays on, draining the battery even when the key is removed and I would like to pull the fuse to disable the radio,etc.

Can someone provide me with the fuse # for the fuse box under the hood for the radio to do this? (searched everywhere online and none of the fuse #'s posted,etc seem to turn off the radio)..
