Electrical Ground Repair Overview
Proper electrical system function relies on secure, stable and corrosion-free electrical 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 replacement.
In general, electrical ground connections are accomplished using one, or a combination of the following attachment methods:
- Welded M6 stud and nut
- Welded M6 nut and bolt
- Welded M8 nut and bolt
Determine which attachment method is used and perform the appropriate or alternative repair as described in this bulletin.
M6 Weld Stud Replacement
Caution
Use only the GM-approved replacement fasteners with conductive finish for electrical ground repair.
1. Select a location adjacent the damaged or missing M6 ground stud having 20 mm (0.79 in) clearance behind the panel surface and 20 mm
(0.79 in) clearance surrounding the M6 conductive rivet stud flange.
2. Using GM approved residue-free solvent or equivalent, remove any grease from the repair site and allow to dry.
Note
Ensure 20 mm (0.79 in) clearance is maintained behind the panel to be drilled.
2010 Cadillac Truck SRX AWD V6-3.0L Page 296
3. Drill a 10 mm (0.40 in) diameter hole through the panel.
4. Remove paint and primer from the area surrounding the 10 mm (0.40 in) hole until bare metal is visible.
Important
The M6 conductive rivet stud as shown, can accommodate a panel thickness range of 0.7-4.2 mm (0.03-0.17 in). If there are layers of
sheet metal, they should be touching without any air gaps to ensure a good ground.
5. Select a M6 conductive rivet stud. Refer to the Parts Information section of this bulletin.
Note
Use the GE-50317 rivet stud tool kit.
6. Place the M6 conductive rivet stud (1) in the 10 mm (0.40 in) hole. Assemble the rivet stud tool (2) with the groove and flare side facing the
rivet stud, then the washer and the M6 nut (3).
7. Using a wrench on the rivet stud tool, and a socket on the M6 nut, secure the M6 conductive rivet stud.
8. Ensure the rivet stud is securely fastened, WITHOUT ANY detectable movement.
9. Completely wrap the threads of the rivet stud with painters tape or equivalent.

Note
The rivet stud and surrounding panel area MUST BE properly refinished PRIOR to the installation of the ground wire terminal and
conductive nut to maintain a secure, stable and corrosion-free electrical ground.
10. Refinish the repair area using an anti-corrosion primer. Refer to Anti-Corrosion Treatment and Repair in SI.
11. Allow the refinished repair area to cure sufficiently before removing the protective material applied to the rivet stud threads.
12. Remove the painters tape or equivalent from the rivet stud threads.
13. Using GM approved residue-free solvent or equivalent, thoroughly clean the rivet stud threads to remove any adhesive and allow to dry.
14. Using a small brush, apply Dielectric Lubricant GM P/N 12377900 (Canadian P/N 10953529) to the threads of the M6 conductive rivet stud.
Note
Fretting corrosion is a build-up of insulating, oxidized wear debris that can form when there is a small motion between electrical
contacts. The oxidized wear debris can accumulate at the electrical contact points causing the electrical resistance across the
connection to increase.
15. Carefully remove ANY corrosion or contamination that may be present on the electrical ground wire terminal.
16. Install the electrical ground wire terminal to the rivet stud.
17. Select a M6 conductive nut. Refer to the Parts Information section of this bulletin.

Tighten
Tighten to 8 Nm (71 lb in).
19. Verify proper system operation.
M6 Weld Nut
Caution
Use only the GM-approved replacement fasteners with conductive finish for electrical ground repair.
1. If the M6 weld nut at the electrical ground location is damaged or stripped, a M7 conductive self-threading bolt may be used to secure the
ground wire terminal.
2. Using GM approved residue-free solvent or equivalent, remove any grease from the surface surrounding the weld nut and allow to dry.
3. Remove any loose metal particles from the damaged or stripped weld nut with a stiff brush.
4. Select a M7 conductive self-threading bolt. Refer to the Parts Information section of this bulletin
5. Using a small brush, apply Dielectric Lubricant GM P/N 12377900 (Canadian P/N 10953529) to the threads of the M7 conductive
self-threading bolt.
Note
Fretting corrosion is a build-up of insulating, oxidized wear debris that can form when there is a small motion between electrical
contacts. The oxidized wear debris can accumulate at the electrical contact points causing the electrical resistance across the
connection to increase.
6. Carefully remove ANY corrosion or contamination that may be present on the electrical ground wire terminal.
7. Install the electrical ground wire terminal to the M7 conductive self-threading bolt.
8. Install the M7 conductive self-threading bolt and:
Tighten
Tighten to 9 Nm (80 lb in).
9. Verify proper system operation.
