Charge System Fault!!
I need some help guys!!! got this display for Charge system fault the other day. bought a new battery and alternator just to make sure. put them both in and still had the same display up, with a voltage reading of 11.2-10.9. Talked to a buddy told me to make sure my connections were tight on the starter, I did, and got almost a full turn on that bolt. Put everything back together and the voltage went back up to 13.2. Took the car out today, and the voltage kept going down, and eventually I lost all the gauges on the dash then shortly after the car shut down, dead!!!!!!! Had a new battery driven out to me at the car, installed it and ..........nothing, wouldn't even turn over. Is my starter fried??? and if it is will it cause my whole system not to charge?? Please, any info will be greatly appreciated, as I am going to be doing the work myself. Thanks in advance.

and 5 min later got the low voltage and charge system fault message again. Also put on lift and tightened the starter bolts and still problem. Thought what the heck and took it down the road to my local shop we use. The shop owner just called and said tech found that I need new ignition switch...that's all. Picking it up about 6pm today!
Switch is from dealership so part and install is $288.David

Just took my 02 coupe in the shop yesterday for exact same issue. Couple days ago the car died on our street and I got it home after few trys and it wouldn't start again and gauges acting funny. Pulled the alt and got it checked at autozone and it was no good. So had to order new one...but in mean time I replace the alt and battery myself (pulled from my wifes vert) and 5 min later got the low voltage and charge system fault message again. Also put on lift and tightened the starter bolts and still problem. Thought what the heck and took it down the road to my local shop we use. The shop owner just called and said tech found that I need new ignition switch...that's all. Picking it up about 6pm today! Switch is from dealership so part and install is $288.

My wifes Grand Prix had the same issue a few months ago, took the alternator in and had it "tested" (they said it was OK) but it turns out it wasn't. There is other circuitry in the alternator anymore other than the alternator/regulator that can go bad. The only real way to know if the actual alternator/regulator stuff is good is a scope, the test setups most parts stores have is too simple for moder alternator testing.

In may case it was. I had my alternator checked again at Advance Auto and they said it was good. Thought I'd stop at Autozone down the road again to check same alt and they showed it fail again. I told them that my alt was good at other place and asked them to put a new alt out-of-box on the tester to see what's up. They tested their own alt and it failed too. I went home and put my old alt back on the car and my wifes back on here C5 and all is fine. Ignition switch cost from dealer was $115.
