head unit fried?

[Bobby322 10+ year member]

I was taking out my head unit to re-do some wiring, and as I was i guess 2 wires touched and sparked with some smoke. I dont know what wires it was. I disconnected the power (yellow) wire and reconnected the extra one that was there. My HU won't do anything...alpine 9884 in a 2004 Dodge Ram 1500. Where are the fuses I need to check? How do I know if they are blown? When can I get new fuses? If thats the problem

Did the smoke come from the HU?

Smoke came from somewhere...I think it was when the wires touched. Not sure which wires touched though

try making a 3rd thread in another section about this. maybe that will solve your problem.

Check the radio fuse in the fuse box, I am not sure if th eradio has a fuse also

I thought the headunit had a fuse itself? If I goto an auto parts store they will have a radio fuse?

It should be the same kind of fuses used in your car, the kind usually found in the boot of either of the front seats. Check around the rear of your HU to find its own fuse.

So I should probally replace my headunit fuse? How do I tell if its blown? What abou the car itselfs radio fuse?

you look at it. if the filament is broken it is blown. get out your owners manual and find out where the fuses are in your car.

But would it be the fuse to my headunit or the fuse on the car? Either way I can get a new fuse at a auto parts store?

unplug the wire harness and there will be a 10 amp fuse, pull it out and yes the auto parts store will have a replacement.

Okay I disconnected the battery. Checked out the head unit fuse and it looked fine (wasn't black or broken). Looked at the fuses in the fuse box under the hood and found one that said "radio amp", the fuse looked fine as well. I made sure the power (yellow), ground, ignition, and the antenna were all connected good. I even switched out the ground and power wire with the extra one there was. Still doesn't even turn on...

how do you have so many posts and not know how to check a fuse.....

Post-tard!

Make sure that when you switched the power and ground wires from the factory ones you did it correctly and soldered the wires well. Otherwise they could be not touching or something.

I didn't switch them from the facotry wires. The harness I bought had 2 power and 2 ground wires so I just connected them to the other...then back and still not working
