1981 C20
Truck was fitted with an old Equalizer (aftermarket) to the Radio. Wiring was a mess (should have taken pictures). Radio was powered only by a constant directly to the battery. Radio was grounded directly to the chassis. Factory wires were cut.
At this point, the horn/dome light/cig light only worked with both doors closed (I assume the switch in the door jamb created a ground).
I removed the radio and equalizer and then had no power at all to anything listed above (doors open or closed).
I began the process of installing a new radio and rewiring the harness as it would have been factory. I still have no power to the radio or any of the others.
*The only strange thing I did while wiring the radio was to splice into the cigarette light wire for constant power as this radio requires it and the truck does not have a factory constant wire for the radio.
**UPDATE - I removed the radio ground from the wiring harness and went directly to the chassis. This made no difference. I checked for power at the ignition once again and it was there with the key on.
