My radio will not turn on and I can not figure out why. I bought the car in the last few weeks with the radio not working. It randomly turned on one time but then died about 30 seconds later.
I have good power to the radio. Both power wires are good, constant 12v and the ignition on has 12v power. Both grounds on the same connector are good.
I checked and their is power to the amp itself. (white/purple wire)
Continuity for the 8 wires wrapped in blue from the head unit to amp are good... no opens or excessive resistance.
Ground on the connector at the amp is good.
fuses 4, 8, 11, 17 are all good
The dimmer function works and it backlights the radio and dims it when adjusted. There is simply no indication that the radio is on.
I opened up the amp and it appears okay. All the cold solder joints are in good shape. I used to work aircraft avionics but as always you can never tell with a visual check.
I am having trouble finding how to check to see if the amp is good. From the wiring diagram and other threads if the amp is bad the radio will show stations/times but no sound. Have not found a thread where if the amp is bad that the display will not come on.
Tonight I plugged the radio into my buddies 93 and it powers on fine. I also plugged in the second stock radio I bought and it powers up good as well. He has an aftermarket radio installed so we just disconnected the aftermarket harness and plugged mine in to the stock harness. I do assume that his amp had the bypass harness installed but not certain as I didn't bother to look
