Charge System Fault
I have a 2000 C5 Corvette, i recieved a DIC message Sytem Charge Fault, my voltage reads 0.7 on the gauges. I replaced Alternator and battery and unfortunetley it did nothing to even help. The car is acting as if the Alternator is bad, it wont allow it to charge my battery. I took the alternator back thinking i got a bad one. they gave me a new one and tested it as well. Still the new battery wont charge. I have no check engine light on and car will die, because the system wont allow the alternator to due its job. does anyone have any idea what this could be? I literally am running out of ideas, i cleaned the grounds i checked the fusable links at the starter i cleaned the connectors by the PCM. Please someone help!!!!!!!

I hope you kept your old alternator to get rebuilt.

1) Have you tested your original alternator? Are you positive it is bad?
2) When you checked the fusible links at the starter, did you test both of them for continuity and cleaned the contacts at the starter solenoid?
3) When you say that your gauges report .7v, what voltage does your battery have measured directly at the posts with a multimeter?
4) Using a multimeter, what is the voltage between the alternator and the positive post of the battery? It should be zero or very, very close to that.

Considering this thread is 5 years old, I'm guessing he got his electrical system fixed.
I too had this happen this week. I have a massive audio system and I was jamming at the time. The pop up hasn't returned so I'm not worried.
I’ve had this message pop up once, but it hasn’t popped up again. Should I be worried? Is there something I can check to investigate the matter, I didn’t have any error codes listed in the DIC
