Radio Testing
Go on the net and google "Bendix auto radio service manual." Look for the models of your radios, usually like Bendix model #s 5BVE, 5BP, 5BPD...Mopar model #s 222,224,225, stamped or stenciled on the radio chassis. I found the manual for my OEM 1965 Barracuda AM radio. The power wire in most cases is red, speaker ground is black, speaker power is green, dial light orange, chassis ground to negative side of power source.
