hi all
i am in the process of cleaning installing an original am radio in my 66 el camino.after connecting the hot wire and changing the bulb the unit shows no sign of life, except when the case touches metal it sparks.i know only enough about electrical to be dangerous. can anyone point me in the right direction as to how to check the radio and hook it up correctly
thanks in advance for your help

The case NEEDS to be grounded! What you are seeing when you "the case touches metal" is the completion of the circuit. FIRST, be sure you have the "HOT" wire connected through a fuse! Be sure the speaker and the antenna are both hooked up. THEN, connect a wire from the metal case of the radio to a GOOD ground. The radio should function under these conditions. If the fuse blows violently, there is a short within the radio, more than likely the output transistor. The most important part is be sure you have the "hot" lead hooked to a fused source. ABOVE ALL, BE SURE THAT YOU HAVE PROPERLY IDENTIFIED THE 12 VOLT "HOT" TERMINAL ON THE RADIO!

Looking at the back of your radio the connectors will be in the lower right hand corner, going from left to right the first two are your speaker connections Neg Pos and the one to the far right is your power lead Pos, and like I said on the Chevelle list there should be a bracket/terminal on the lower right hand of the radio, this is with the radio facing you, this is your ground. But you can ground any where on the radio chassis! as far as testing out of the car, use a battery/battery charger and a speaker, hook pos to pos terminal on radio hook neg to radio chassis, and hook the two radio terminals to the speaker, using aligator clip jumpers, if this is beyond your capabilities maybe take it to an automotive radio shop that installs.

Correct me if I am wrong but there should be a threaded lug on the back of your radio that
gets bolted to the support brace hanging down from above the radio. That support brace is intended to support and stabilize the rear end your the radio. It is also the radio case ground.

Bill,
It CAN be used as a ground, but there is a separate connection in the harness for ground. If the radio was removed before, chances are the bracket isn't even there anymore.
