Electrical Grounds
Proper electrical system function relies on secure, positive, corrosion-free ground connections. Loose, stripped, or corroded connections increase the possibility of improper system function and loss of module communication. These conditions may also lead to unnecessary repairs and component replacements.
In general, electrical ground connections are accomplished using one, or a combination of, three attachment methods:
- Welded M6 stud and nut
- Welded M6 nut and bolt
- Welded M8 nut and bolt
CAUTION:
Use GM approved replacement fasteners with conductive finish for electrical ground repair.
Determine which attachment method is used, and carry out the appropriate repair.
