I have a 98 Corvette with 24000 miles. I am having an issue that I can't seem to figure out. I had the battery replaced. I drove home and the voltmeter began fluctuating, "charge system fault" pops up on DIC, and eventually "low voltage". I got home and the car was dead! I put the old battery back in after I charged it. I drove the car yesterday. "Charge system fault" still pops up. The voltmeter is still fluctuating; 9,11,10,12...etc. WHAT CAN THIS BE?? I had the alternater checked and it functions within normal limits. The car also does not "draw" from the battery when turned off. This is frustrating!! I can't drive it to the shop because I am afraid that I will run out of "juice" and get stranded. Please help me through this!
Check your ground wires. Look around the starter just in case something is touching one of your headers. You'll need to do a search to find the locations of the grounds.
Try wiggling the battery cables while its running and see if your voltage indications improve. If not, next check the battery wire to the starter motor not forgetting that its hot. Also, there is a ground connection to the frame between the battery and fuse box.
Yes, I would check the main power wires (plus and negative 12V both). The main power wires are the ones that run off the battery and the alternator and the engine and the fuse blocks and the car chassis. Check the ends for corroded or loose connections. In all likelyhood, you will have to actually remove them and clean them to make a difference.

I remember a guy on www.ls1tech.com had an issue with "charge system fault" from time to time...
then it really started acting up.... it turned out to be one of the wires connected to the starter. The wire(s) just as they enter the terminal (that bolt to the starter) were corroded. He says that he gave a very light tug on each one and the trouble was caused by one wire that was severely brittle resulting in poor voltage transfer.
he ended up splicing in new wires and terminals and he said it worked like a charm.

Try messing with those wires...
I also had problems with the starter wiring causing a "charge system fault". The wires were extremely brittle from heat exposure, and were literally falling apart. I ended up splicing in some new wire and adding thermo-tech heat resistant sleaving. I have had zero issues since.
