My mechanic has passed away and I am getting warning lights related to ABS, Traction Control and service soon. I thought I might try to clean some ground connections. Where do I start? Any help would be greatly appreciated.

IMPORTANT ELECTRICAL INFORMATION (Long!) - Corvette Forum
Having clean grounds on our C5's is critical.
Good luck....
Interesting that you bring up the battery. These lights came on when I picked up my car from the repair shop. They said my old battery would not start the car and they then installed a new battery. Can a new battery be bad?

Bill is the man when it comes to C5 electrical issues. I would even call him a guru, he's the man who many go to when they have electrical issues. Trust me, a lot of people go to him :L
I had dead battery symptom, and with help barely got her to start. At home, I hooked up brand newSo,,,,,,,,, What did you find wrong with your C5????????????
I had dead battery symptom, and with help barely got her to start. At home, I hooked up brand new
battery tender, & tightened up neg battery post with 8 mm wrench, then attached tender up.
It first charged up to 80%, then 100% charged for few days. I tried to start today, and it acted like it had barely charged the battery, but according to the Bat tender, it was 100% charged. I'm thinking now though, one or more, negative ground junction box is to blame, cause when I start to turn over, just click, and some humming noise with other rumbling noise in the back of the coupe, (could the poor ground cause the CD changer to start stop, several times cause that's where the clicking sound is coming from)????
thanks a million!!

The battery is direct connected to the starter. Unless, there is a loose block ground connection OR a loose/corroded connection on the starter solenoid.. all should be good..
Take the battery out and have it fully tested. CCA and reserve capacity. If it fails, replace it.
Here are two schematics that you wil find helpful"

Make sure that the battery terminals are clean and properly tightened. 11 ft/lbs Torque
