97 blazer ground locations
 

Hi .

I was wondering where on my truck can i locate my ground wire's . Im looking for ground wiring for G117, G416 . Im looking for ground wires that are bad from just old age . I would like to replace all of the copper one that are not covered with insilated like most of the other wires are . I found the one from the fuel filler to the rear crossmember . I was wonder how many are under the truck that are in need of replacing from old are , you get my point right . I have another post about a insrutment cluster fuel gage going wacko on me some of the time doing a full 360 turn on the gage . Im told that bad ground wires can cause this . It only happens when Im driving for some short time and sometimes its noromal .

So If someone can give me some insite on how to loctae the ground wire on the truck it would be a great help . Most of you online service manuals like alldata , mitchell and so one wont tell you this info , I dont no why but they dont .
