Lost 12V power after rewire. Help!

**SwapMeet** · 11-28-2004, 02:33 AM

I've seem to have lost my 12V power going to my headunit sometime during a rewiring project.

Background:
2000 Ford Mustang, aftermarket Kenwood head unit installed by Best Buy.

What I did:
I wanted to tap the 12V wire to power a mobile monitor. However, sometime during the process I lost power from the factory harness. Now I can't power either the monitor or the head unit, together or separately. I've checked voltages with a multimeter.

What I've done since:
I've checked all the fuses in the passenger compartment. I looked up my fuse box diagram and swapped out any fuses that were associated with the radio.

Any ideas on what happened?

Fuses in the engine compartment?

Check all the butt connectors and see if a wire pulled out? I know how some of those "pro's" install, and it makes me sick. If no fuses are blown, there is a good chance something simply pulled out. Look in the areas that the installer would have messed with.

Checked the butt connectors myself. In fact, I redid the butt connectors on the 12V and the ground because theirs was sloppy. At least theirs worked.

I'll take a quick peek, but I'm not sure if there are any fuses there that are connected to the radio.

Are you missing constant 12v or switched 12v? If it's constant, you probably blew the dome light fuse.

I went to Wal-Mart and picked up a fuse checker. Turns out one of my fuses in the engine compartment was bad, I just couldn't see it at first. Thanks for all the help.
