After a tuning session I was on the way home and got on it. As I started to slow down I looked at the gauges and the voltage gauge was maxed and many of the warning lights were lit up like Air bag light, abs light, etc. I got back to the house and then went out of town. When I just got back tonight I tried to start the car to see if maybe the alternator had gotten hot and the car was completely dead.

I hooked up the jump box and fired up the car and the voltage gauge once again maxed so I cut it off.

What could be causing this? Electrical short maybe?

 

check to see what the alt is putting out. should be close to 13ish volts. the voltage reg could be bad.

 

Internal reg is messed up on your alt. Put a meter on the output and check it.

I agree with the above... however, have you washed your engine bay lately? I got a puddle of water that accumulated where my power plugs into my altenator after washing the engine bay. It did exactly what you are talking about. I got an air compressor, cleaned out the puddle of water in the socket and it fixed the problem...
