ok so i am riding around delivering pizzas and went to plug my sweet dominos car topper in my ciggerette lighter like i always do and zap there goes my radio. No big deal i figure cause i have blown a fuse before the same way. So i go buy some fuses switch out the bad one, and nothing no head unit no lighter still. So i ust start replacing every fuse in the box that i could, checked the little fuse on the back of my deck. Whay else could be the cause could i have killed the head unit???

Fuse under the hood.

Also I would make Domino's pay for it all. Everything was fine until you plugged their equipment in.

Break out the test light and start testing fuses.

I seriously doubt it's the sign, it's probably just a bad cigg. lighter socket or something.

What kind of car is it?

Check the fuse again, theres probably a short causing the fuse to blow as soon as you put it in.

never use a test light use a multi meter, test lights can blow air bags, cause damage to the computer along with other sensors.
