Hey folks, looking for a GM tech to possibly help me with some information. I am replacing the negative battery cable assembly(with current sensor) on this truck. The old cable … bolts to the rear of the passenger side cylinder head. The replacement cable … is longer and obviously the mounting location has been changed. But I cannot find any information to tell me where to bolt it to the engine. There is a bulletin for a faulty current sensor but there is no info in the bulletin about where to install new cable. This truck has had that campaign done already and the updated cable is faulty. Any help would be appreciated. Thanks, Marty

I've gotten my answer. Side of the block just in front of the starter.

Just for reference, GM SI doc # 3249538 covers the updated location.

Noteworthy also, is a revised torque specification from 33 lb/ft to 16 lb/ft, at the new location on the block just forward of the starter, since the location utilizes an 8mm bolt compared to the use of a 10 mm bolt in the original location.

That's because on the updated cable the eyelet to mount it to the side of the block is smaller in diameter. The original bolt will not work.

Correct. I updated my response to include the difference in fastener size, so that anyone receiving the updated cable is aware that it is the correct cable and requires the revised location, torque spec and fastener.

Thanks, Martin. There's a picture that thats shows the new location that Robert Duncanson posted on iATN. I don't know if it can be shared though.

Wow, Robert Duncanson was also very helpful. I also looked for notes in the parts catalog and came up empty.
