Audio Systems: original car radio installation, walmart stores, battery checker


Question
QUESTION: I have a factory delco cd player for my 1992 camaro, the original wire harness is still wired in the dash.  I have the same model radio that plugs into the harness. The radio worked in the car that I removed it from and the radio I removed worked with the wiring harness thats still in the car.  The new radio that I am plugging in will not power up but everything was in working order before I made the change.  The fuses are not blown.  Can you help me with any advice on why this radio will not power up.

ANSWER: I need to know what car the radio was removed from. It may have different hookups!

Can you check for 12 volts at the power connections?  That will help you to know if it is connected properly.

The above site will give  you a wiring scheme that may help you in determining the where the wires go.

Let me know if you need further guidance.

QUESTION: the radio was removed from a 1992 camaro and installed in a different 1992 camaro,the radio model# is 16168841: Delco LOC II AM/FM/CD Player  

Answer
Okey.  The wiring should be the same.  Since you are not getting power you must check it out.

My suggestion is to get a battery checker (best deal is the VOM tester at Walmart stores, electrical department, for $9.83).  Use it to test for 12v at the power lines to the radio unit.  You must verify that both power wires lines are getting through.  One is for constant power; the other gets switched by the ignition or power button on the radio unit.

Then: when you are sure it is getting power and the unit comes on you must verify the wiring to the speakers and that the speakers are good in the new car.

Hope this helps you track it down.

PS:  You can bench test the unit by pulling the unit out of the car.  Power it up with long wires from the battery to the radio. Using a known good stand-alone speaker hook it up to one of the channel outputs of the radio. Then test each amp output one by one.
