If anyone could offer me advice I'd really appriciate the help. I recently got a Pioneer Avic-D3. It was nearly free, and I realized at the time it wouldn't fit, but I am pretty good with fiber glass so I snagged it. I got all the wires connected to the wiring harness that came stock, soldered them and taped them off. The problem I have is that I can't get it to power on. The truck is all stock wiring, and I followed the wiring diagrams. Can anyone offer me any advice? Did I miss something or is it a bad unit?

AAAAAHHHH!!!

Did you use a volt meter to verify that you have 12 volts on the red and yellow wires of the deck? When checking this, place the black meter lead to the chassis of the radio. Did you ground the radio?

I have tried several places to ground it. First I tried splicing it to the ground wire that was already on the stock wire harness. Then I tried grounding it to the radio chassis, then I tried grounding it to straight to the floor board. Only difference is when I grounded it to the floor board the speakers made something of a static sound, then all my dash lights and head lights turned on without me flipping any switches.

And the answer to the first ? is....

Yes I am getting a good reading on the voltage meter. Sorry, completely forgot to answer that part.

is there a fuse in the back of the D3? look under the plug, if there is one that is where it will be.

Yes I checked the fuse and it looked fine. I replaced it just to be sure. Had no effect. I'm getting the vibe that its a bad unit. However the dudes at best buy tested it and said it ran fine, so I was first assuming that it was something I did or didn't do.

When you checked the voltage on the red and yellow wire, did you use the chassis of the radio as your ground reference for the meter_?_ There is a logical reason for doing so.

No I used the firewall wall to ground it.

i think it is a bad unit. a simple power problem should never be this hard to figure out. if you have 12v+ on the red and yellow wire and the black wire is grounded to metal and it still wont even turn on

There could be a burnt trace on the ground wire of the radio. When I am checking a radio to see if it works, I connect ground to the chassis of the radio via the large alligator clip on my bench. The guys at Best Buy probably did the same thing. I have seen more than my fair share of Pioneer decks that have a bad ground path on the ground wire. These radios will work if grounded through the antenna or through the chassis in some applications. If you use the chassis of the radio as a ground reference for the meter, this will tell you if the radio is grounded or not. If you use chassis of the vehicle as a reference for your meter, you will only be testing power and ignition. I usually tell people to use the chassis of the radio when performing these tests. I must have forgot to mention it here.

couldn't you just meter continuity between the ground wire and the chassis to tell if the ground trace is burnt? just a thought -------------
