I have a 97 v6 camaro and when i was driving it i went to turn on the ac and the car went black and shut off. I pushed it to the side of the road and cheked the voltage the battery was giving me and it said it was like 6 or 7 volts, i removed the positive terminal and it reset itself and worked, but similar things have happened since then. Also the spedomiter shot up to over 120 even though i was not moving Is there some shut off built in that resets. The battery is new and the conection is good thank you for any help

 

make sure the surface of it is clean.. you can clean it with baking soda + water... and check the terminals if its a maintenance free battery

 

yo, same thing happened with my grand prix, after about a month of haywire gauges and shutting off all of a sudden, it turned out to be the alternator. it costed about 75 bucks with a core return.
