i need help. big time
i have a 05 corvette with just under 10k miles. its just out of warranty and recently i have been having problems. while driving one day all of the warning lights came on the dash(low oil,low tire pressure,abs,brake,etc) every possible dummy light came on. i was getting false readings from the fuel gauge. then the next day i went to drive it and everything was normal but it wouldnt start. just clicked but no dead batt. i pulled the battery for 48 hours. worked flawless for 3 days. now i have the same problem. is this something wrong with one of the control modules?

Probably not. Most likely, it's the battery. You need a new one. There may be a slow drain when you shut the engine off, but if it's the original battery, it's just not getting enough charge. You've got to drive the C6 at about 2K rpm or better for 10-15 minutes to just barely keep the battery up.

thank you. but it seems odd that it would do this all of the sudden. it has sat for longer periods of time without being driven and have never had any problems, the lights came on while driving, wouldnt it have been charging the whole time?
