I have this Pioneer head unit laying around that I started putting in today, and for some reason my car was getting come weird electrical signals. I was getting no constant current from the battery, only the on/off current coming through the blue wire. I found out that if I put both the power (red, on/off) and the battery (yellow, constant battery) lines on the blue line that I could get the head unit to turn on. I was then wiring the speakers up using butt connectors (trash) just to make sure everything worked before I soldered them and got all of the speakers to work. Then I was messing around with something and my driver's front speaker stopped working, it was working before so I tried connecting the wires again and still got no signal. So I went to do it again and then my entire head unit stopped working. I tried reconnecting it the same way that I had previously but it's not working either.

Is there any chance that it's just my battery going a little dead after me working on the car for so long? I don't think it is because my car started right up.

Another problem that I've had is that there's a short in my dash that makes it reset to 1:00 every now and then. I found that when I rubbed the wires that are supposed to be the battery and on/off wires together the dash would light up and reset to 1:00, not sure if that has anything to do with it.

So basically, anyone have any tips? Like I said everything was working really well and then it all went to shit. Also would anyone in the area experienced in audio be interested in installing my head unit if I can't get it? My car has no physical harness, just the wires that go into it.

End long post.

CLIFFNOTES

1.) Constant power wire getting no power, but on/off is.
2.) Right front speaker quit working, then complete head unit turned off and won't turn back on.
3.) Short in the dash that I can recreate my touching the on/off and battery wires.

ok if you put the what would be constant wire together with the remote wire, you more than likely blew a relay.

what you should do, is take and run your own wire say a 12 awg or 14 awg run from the battery into the dash. giving you your constant. Check your ground wire, try running your own ground, then use the blue wire for your ignition wire.

if running your own power and ground, and using the factory remote turn on doesn't work, see if connecting the red wire from the head unit in with the battery lead, if it turns on then you have blown the relay.

so.. you could just try doing this at the battery, by putting your yellow, and red wires together on the positive side of the battery and the black wire to the ground, if it cuts on. your good. if it doesn't check your fuse, if after all that is said and done and it still doesn't work.. you blew the head unit,
