For instrumentation on the engine, the #1AWG serves as the ground as my sensors are all single-wire. They rely on the engine block for the ground path. The alternator is grounded to the engine block as well, on the same bolt that the #1AWG ground comes in. Hope that helps!
Interested to see your wiring post, my boat is in need of some serious attention on its wiring. Hoping that your wiring post will be as detailed as your stringer post.

Thanks for the time you have taken to keep us all informed of your progress.
