Griff,
Just FYI, according to this graphic the case is ground.
I am still evaluating all options...
Sorry, I was extremely busy (cleaning the chimney and doing other things outside).
Thank you. Obviously I was wrong. I've added the ICM to the list of things I run dedicated ground wires to.
I use one or more busbars,
similar to this, to distribute dedicated ground wires to components throughout whatever vehicle I'm rehabilitating/restoring/improving.
I run a heavy wire/cable (8 gauge or heavier) from the studs on the end to the battery's negative post. In turn, I use 10 gauge wire to carry the dedicated ground to individual components.
If I'm using a tree-like dedicated ground distribution system, I use 8 gauge or heavier wires to carry ground from the main ground busbar to other ground busbars.
A dedicate ground distribution system, like I've described, is more reliable than the chassis (common) ground system used on most motor vehicles.
I don't like the screws used to mount the ICM and connect it to ground. (Screws into sheet metal are too easy to strip out ... creating an iffy ground.) I'd prefer a nut, bolt, and lock washer to make sure the ground connection is tight.
