I have a 1984 Chevy Silverado and I was working on an electrical issue with my radio and when I plugged radio power back on to the fuse box lower receptacle (constant on) and heard a pop and it killed the radio and the instrument panel lights.
I've check and tested the 5amp fuse for the instrument panel lights and it is good.
I used my voltmeter to test the instrument panel light fuse at in-coming power connector and it's dead along with the other 2 lower receptacles where my radio once connected.
Everything else electrical works on the truck, so I believe my radio was the cause.
The wiring circuit schematic I'm using for the fuse box circuit is not specific to my truck and a little confusing to me.
I believe there is a pink wire from the fuse to the instrument light circuit, but I'm lost at what color wire coming from the battery to the fuse box and if there is a fusable link in the circuit.
Thanks for any help on this, Chuck

Begin by disconnecting the radio. Following the steps in Diagnosing dash instrument lights (http://forum.73-87chevytrucks.com/smforum/index.php?topic=26558.msg221363#msg221363) should help you reestablish power to the dash lamps. It sounds as though either the radio is faulty or was miswired into the vehicle.

BD,
Perfect! I was tracking on to the Gray wire and you filled in the blank. I'll get back to you. Thanks

Found the problem. The blade connector for the green wire pushed out of the plastic plug on the light switch and caused a open. Thank you Sir!

Any time. Thanks for the update.
