Here is the problem, I installed a panasonic radio in place of oem radio in 2001 tahoe (Does not have bose sys) works fine but runs battery down. Why? If it sits for a day its dead. Ive been having this problem for quite some time and have finaly narrowed it down to the Aftermarket Radio. Using metra wire harness. any help would be great.

Have you removed the radio to see if you still get a battery drain ?

Actualy now that i think about it when i wired up the wire harnes at first i got no sound from speakers, i finaly figured out that if i grounded the orange wire which i think was the power antenna lead that i got sound. Does this sound famillular to anyone? is there another way to do it? been searching the net and not finding much on this problem. Thanks

Hmm you grounded the orange wire.. posted_image

orange is usually your dimmer wire. The problem you are having is most likely the integrated amplifier staying on after the car is shut off. If you are using 70-1858 harness from metra or something similar cap off the orange wires, connect both blue wires to the blue wire from the aftermarket radio. This is your turn on lead. When properly connected the amp will shut off with the radio.

Your right i think it was a blue wire and i believe that is how i have it hooked up. but i will double check wireing tonight and see if the amp is infact shutting off. Im pretty sure that the wiremap on the harness packege called the blue wire power antenna and thats why i did not hook it up at first and got no sound. But i will double check all wireing this evening. Thanks

That is definitely the right way to do it but just curious, how would the amp turn off the radio when the radio is the source for the turn on lead?

According to this wiring chart it looks like you grounded the 12v constant that keeps the radio memory active. That would explain the dead battery.

If you ground the 12+ volt constant, you'll short it, and cause the fuse to blow.

I suggest going with sneakycyber says or if you're really not sure, put your DMM in series with a component and see what is actually pulling amperage.
