I was driving my car 10 at night today and all of a sudden, my gauges doesnt work and no idiot lights comes on. I thought it was the alternator since same thing happened before when my belt broke off, but its not.

Im thinking a blown fuse but I havent checked yet, its too dark to see.
I havent driven the 7 for a week, and the first time I drove it this happens

 

sound like blown fuse

 

Do you just mean the gauges don't light up, but the gauge arms still move? If so it is likely the light switch that has a problem. If this is not what you mean, I'm not sure what could nock out all the gauges at the same time if the car is still operating.

 

the gauge doesnt move, they light up but it doesnt tell any kind of reading.
The car is running rich after this happened. Since the tach gauge doesnt work I been using my SAFC that is installed used as a tach for now.

 

found out it was a blown fuse, the meter fuse.
so i replaced it as i was heading out from work and on my way home it blew again......

so there is a short somewhere....fun part begins from finding it :/

 

hmm, check your wiring under the trailing coils. i had a problem like that before and it was that the wires under the trailing coil shaved and it started grounding. im not saying that could be your problem but check other than that check if you have moisture by the fuse box
