I've got it all worked out now. I had a good ~15 minute call with Chris yesterday and got everything straigtened out. I redid my engine ground and now I have a 2 AWG cable running from the battery negative terminal to the top of the rear rotor housing. The same point serves as the grounding location for the coils and a 4 AWG wire connects it to the firewall for the chassis ground. With this better engine ground hopefully I can avoid having to run dedicated ground wires to the alternator and starter bodies. I'm still debating if I should add an additional 4 AWG ground from the battery negative terminal straight to the chassis.
