Alternator and starter wiring question.....

Hello to all electrical junkies out there. Just a quick question to tap into your expertise.

This is concerning a very simple DC system. I want to limit the amount and number of single "O" cabling.

This is the scenario.........

There will be a negative bus. From the bus there will be a single "O" cable tied to the grounding lug on the engine. Both batteries negative side will tie into the negative bus as well.

Instead of running two additional cables I am considering wiring the negative leads from the ALTERNATOR and the STARTER directly to the grounding lug. So they would share the lug with the single "O" lead to the negative or ground bus and then on to the negative lead on the battery.

This is just an attempt at a cleaner set up and the reduction of heavy cabling. I am hoping that this is an acceptable approach. Or even better the preferred method.

I appreciate any input or con. Thanks in advance.

Fine, just make sure all the paralleled termination rings lie completely flat against each other, no gaps, clean metal surfaces and no more than those three stacked on the one lug.
