Well, long story short i took al my stereo equip out yesterday, and i THINK i left a CD in the HU. Whats the best way to power it up so i can get the CD out without wiring it all back up?

hmmm, i didnt try the power button. I hit the eject CD button though, and when in the car, it would turn on when eject button was hit.

any other ideas? maybe someting special with the pioneer premier 780s?

Then again, i just touched the wires to the bolts on the battery, will that be enough juice or wil i need a secure connection?

use a old computer power supply. hook the batt (red) acc (yellow) to the yellow wire on a molex connector (12v) and hook the neg (black) to the 12v ground on the molex, right next to the yellow. then put a jumper between the green wire and ground right next to it on the ATX plug. PM me if you need pics of it to show you exactly what to do.

You may need to touch the ignition wire with the positive

normally you have to put the red and yellow wires to pos. and black wire to neg. press power (or source), then eject...

****it! i looked at the ignition wire and questioned myself, but i didnt wanna risk anything that may damage the unit lol.

tie the red and yellow wire together touch to the positive terminal then ground to negative, it might spark but that is no big deal. If it doesnt power up there is something wrong with your cd player

yeah, red is the switched power wire that turns your h/u on when the ignition turns on and yellow is the 12volt power wire, both of these need to connect to the battery pos

you have been here for 3 years and had no clue that the ignition wire has to be powered up along with the constant and ground in order to get a deck to power on? idiots!

not to make you feel dumb or anything, but the remote wire is 12v out from the deck..


..putting power into the remote may cause problems in the future

spark plugs.

there is no good way to tell, depending on the unit, you may burn up pieces on the board...hopefully without power being on the switched, nothing will be wrong

the only way to know is after install, reattaching everything and making sure it works
