I was installing a hand me down deck last night and I connected all the appropriate wires but I forgot to cap off one of the unused wires in the bunch. I went to put the cd player in the dash I saw a spark. Not good. I looked in the bunch and saw the wire un capped. The cd player worked before the spark and now it wont power on. Do I have a new paperweight on my hands? thanks for any help.

Have you checked for a blown fuse?

I checked on the back of the reciever and I checked a few in the fuse box. Would I need to check anywhere else? I will check more thoroughly after work. Do you think my receiver was protected and should be ok?

I checked all the fuses and they are fine. I also hooked the stock deck back up and the security code screen showed up so it seems to be getting power. I just want to know if I need to get a new deck or if it can be repaired. any help is appreciated.

what wire was uncaped???? seems to me no unused wire should have had constant power running to it.
also check all fuses even ones not related to the HU under the dash and under the hood. last time i blew a fuse with my deck it was one of the ones under the hood took forever to find.
if all fuses are not blown. and the deck wont get any power then sounds like an internal deck problem.
i just cant imagine an unused wire not being caped cuasing this problem. i think something may have been hooked up wrong if you had an extra wire that had enough power to blow soemthing like this.

it was one of the channels on the deck. If all the fuses are good should I plan on getting a new deck?

If it was just one of the channels on the deck, then try hooking it up without that channel hooked up, or try it with just the battery, accessory, and the ground hooked up to narrow everything down. If it stil don't turn on, hook up a voltmeter to the wires. You should get voltage on the battery, and the accssory wires when the car is turned on. Then check the ground wire for resistance. I think if it's at 0 then its good. If it's at infinity its your ground wire then. If one of those other wires not getting voltage you will have to bypass them by manually wiring. If all the wires are good, then it's the deck, but if your fuse didn't blow it shouldn't be the deck.

ah i thought you meant a wire from teh cars harness wasnt capped. this makes much mroe sence now. if the positive of a channel touched baremetal it could pull alot of power and end up blowing something. i would think this is what happened... you may be able to get this fixed for reasonable at a repair shop. or if its under warranty.

If that was a speaker output wire... (pos connect wire) and it grounded out to body... may have blown something inside the HU or damaged the power supply.
Best to remove the HU and bench test it with a 12 volt power supply capable of ~10A. current. If it does not fire up the display and other features... power supply or maybe an internal fuse element if blown.
This test will at the very least, confirm whether the HU is getting power into the harness etc. If it fires up... fuse problems in car somewhere. If it does not fire up on bench test, damage to internal parts in HU. A trip to repair shop or scrap it. A repair will cost a minimum of ~$60.00 bench time + parts. Only you can determine if the HU is worth that much or not.
