CHARGING SYSTEM MALFUNCTION
1998 Chevrolet Cavalier • 225,000 miles
When i start my car and turn on some of my acessories (lights, radio etc) the car will start to lose power. When I turn everything off it will keep running. But when I keep it running for a few minutes with all acessories off the entire dashboard stops working ( speedometer, rpm gauge, temp gauge etc including my running lights, signal lights) then when I turn my headlights on and off the dashboard fickers. But the strangest part is, is that I can still drive it, none of my lights work but it will keep running until I turn it off then it won't start back up again. Its very strange, I tried changing the alternator and battery but apparently that wasn't the problem. I hope you understand what I'm talking about,
Any electrical related modifications to stock wiring/accesories? when did this start happening?
Just recently, I also forgot to mention that when I boost the car and leave the jumper cables on the car is fine everything works
How do you restart it?
It will start a few times after the boost but then the battery is dead then I boost it again
Test voltage at battery when car is running with things off and then on.
Voltage at battery with things off was 5.2 volts, but when I turned my headlighjts on the car shut off.
You mean 15.2 ? car wont start with 5.2
I boosted it and measured the voltage while it was running without the jumper cables on and it was 5.2 volts
Then after the car shut off I measured it again and it was at 7.9 volts
Dont make sense. is it a new battery?

How do I replace a battery in a 2009 Chevy Equinox LS with a 3.4L V6. Most cars are straight forward, this looks difficult. Shame on GM. Thanks.
