C6 wiring diagrams or ground locations?
 

Anybody have any? If not, are there any common grounds that have issues on these cars? I have had a couple of odd glitches here and there and wanted to check/clean all the grounds and see if there are any common grounding issues with the C6 like the C5 has. I already cleaned the ones on the top of both frame rails behind the headlights. Any others? Thanks.

There are 7 total, as far as I can tell. One more near the battery, 2 in the "passenger area", and 2 more behind the rear axle. These are usually pretty trouble free, unlike the C-5s that had the multi-pin connector at each ground.

Thank you! I just want to give them a once over to rule them out. The two on top of the frame rails that I did clean were still painted over, they didn't even clean the stud down to bare metal before bolting the terminals down! There were a couple little spots of metal showing and that's it.

Check the ground going to the block too (near the starter I think) as I heard some had isssues with it not being properly tightened. :cheers:

Cool, thanks. I'll give that a once over also.

Do you know where the ones in the passenger area are? I want to check mine too.

I've found what appear to be 12 total in the service manual.

There are 6 in the Engine compartment labelled with a "G" in the list.

Sweet- thanks!!

I have a pdf that shows the ground locations and includes schematics. This was a dealer only pdf that came out at the introduction of the C6. I dont know if it would be of any interest nowdays but if someone knows how to send an 11 meg file and is interested....

I'd be very interested, but I don't know how to send an 11 meg file lol.

Thank You!

Working in conjunction with that excellent ground map, use this to see exactly what is tied into those ground connections:

:iagree: Information overload! Printed and filed.

Great info. Thanks.

Um... I think I found 13? I pulled my info from a 2007 Helms.

2007 C6 Corvette Grounds

Ground points and what they control:

G101

G102

G104, G303, G108

G105, G107

G201

G202 1 of 2

G202 2 of 2

G301

G302, G401, G402


On 2nd thought, 12. One is for convertible OR one is for Coupe

Ok, we're good on 12. Pick the car type and you use a different G spot!

that is all very good info for the c6.. has anyone similiar info with schematics for the c5 which i recently acquired?? thanks,, carl

Good link to radio related diagramsL

Great Thread!!!!!!!!!!!!!!!!

I know this is an old thread, but great info. Crabman, if you still have the mentioned PDF, I can walk you through sending it to me. Thank you.

+1 - am having ground issues too and would like the PDF if possible.
