Hello All.

I have a 91 350sdl with the Becker 2 piece unit. The car was bought off of an estate, owner passed away.

I knew the radio did not work when purchased. Sent units off to be checked out, both came back ok, seperate and together.

Prev owner had the 8 amp white fuse in the fuse box tin-foiled so that it delivered as much current as the circuit wanted!

I replaced the tin-foil fuse with a correct one.

Put the radio back in, coded it and nothing happens. Went to the rear amp unit and sure enough the fuse blew. A 7.5 amp fuse is present. book calls for a 5 amp.

Nothing on the radio works when you turn it on, except the antenna goes up and down.

Oh, the previus guy also cut the two supposed anti-theft and cellphone wire off the one female connector.
