Hi Guys.
I am looking for a breakdown of the earth points on a 2002 Blazer.
As in where the earth wires attach to, specifically the starting system.
I found that earthing the fuel tank sender directly in its loom stops a lot of the fuel gauge bounce issue.
And a poor earth on the tail lights taking out stop lights.
So I think this might be a bit of an issue with these vehicles, maybe?

Any help will be greatly appreciated.

 

Are you meaning a "ground" issue?

 

It’s commonly called a ground here in the U.S., perhaps that’s why you couldn’t find this info when you searched, because it’s been discussed multiple times on here and the S10 forum. A huge improvement would also be completing the “big three” mod. Search around and you’ll find how to do that; basic electrical knowledge is all you’ll need.

 

All the grounds are listed in the attached document, starting with G100. Exposed grounds have a tendency to get corroded after some years.
