1991 350sdl with becker 1432 unit. just bought car, radio turned on once, then quit. sent amp and head in, bench tested fine seperately and as a unit. re installed, amp unit blew out the 7.5 amp fuse. Also, the previous owner had wrapped aluminum foil around the white 8 amp fuse in the fuse box. Now, I know aluminum foil is a field expedient, but there was a good white spare in the box. Anyway, a wrapped fuse is NOT a good sign!! I put a good fuse in, turned it on, the antenna goes up and down when I turn the radio on, but after it asks for the code, nothing. then checked the amp box, and saw the blown fuse.

The owner also snipped the anti theft wires from the one pigtail going into the head unit.
