I have NO idea how too explain this problem so ill try keeping it simple:

I got no elecs inside the car, no didiotlights, no gauges except speedo...now if that was the ONLY problem id be happy with the thought of it being a fuse that has cracked.
Things is, When the car is running and i turn my dashblights on, i get the warning sound that u usually get when ure leaving the car parked with the lights on.

Did more fuses go at the same time or does the car think it isnt running..tho it is..?

 

Check the basics: Fuses, wiring, grounds, alternator touching an intercooler lol (happened to me).
