Question about Pioneer DEH-P5800MP CD Player

DEH P5800MP No power

I have had this stereo installed in my car (85 Corvette) for 6 months with no problem. The power antenna motor wouldn't turn off so I disconnected the wiring to it; when I did this the head unit and interior lights would not get any power either. I reconnected it, but stil nothing is getting power. I checked all the wiring and fuses that I can get to, but I no longer have the keys, so I can't get the head unit out of the dash.

Re: DEH P5800MP No power

On alot of vehicles, the power ant and/or illumination wire for the factory radio ties into the "courtesy circuit". Normally, the scosche factory plug adapter takes the proper action with this wire. For custom install, sometimes it's needed to ground this wire, sometimes it need be tapped into the deck's "remote" (blue) wire, and sometimes it need be left alone! Example, on a 1987-1993 S-10 pickup, you need to connect the "ill" wire of the aftermarket deck to this (usually orange) wire in the dash, or you'll have no dome, dash, or running lights... hence "courtesy circuit"!!! hope thius helps!!!! and footnote, its always good to hook this wire up as most decks nowadays will have an automatic dimming feature that senses the voltage of the dashlights being on... so at night when you hit the headlights, the deck will dim to ease the eyballs.

When you get the keys, or whatever try unhooking the power antenna wire as it comes out of the back of the stereo. Otherwise your guess is as good as mine.

Pioneer DEH-P5800MP CD Player not powering on.

did you try the fuse behind the wireharness. if so check the yellow wire and the red one for power. also check if you have ground on it. if you want to make things simpler try to connect the black wire to the battery neg. and the yellow and red together on the positive of the battery and see if it turns on.

I installed a pioneer Deh P49001B car stereo in a 1997 dodge stratus with wiring adapter from best buy. everything works great until you switch on the lights. all power to stereo is gone.

to solve the problem with it turning off when u turn your lights on is that on the back side of your radio is a spot that says max and something else keep your ground wires conected just how they are but get u a a 14 to 12 gage wire a cut u about 6 inches and use one end and connect to your other ground wires (with Connecters ) and the other end and with a closed end connecter with the little hole in the center i cant place wat its called but any ways put it where that max hole thing is where there is a screw there and that should fix that problem cause i had that happen before .. but make sure your antentia is pluged iin to ok .. good luck Paul,
