[C320-list] Ground Bus Bar - Perkins M30 Alternator

[Jeff Smith]

To all with a Perkins,

Has anyone installed a ground bus bar for the M30 alternator? The common ground for the Perkins M30 is a bolt at the back of the engine. When I removed the bolt to ground my electric lift pump, I inadvertently severed three ground wires that were also attached to that point (alternator and something else I have not traced). My thought is to install a ground bus bar with one wire from the back of the engine and mount the bus bar somewhere close. Then I can simply connect my grounds on the bar.

Amazon sells a Blue Sea Systems Common BusBar (rated up to 250A, though I am looking at the 150A version), with 10 screws and a cover. I am curious if anyone has done something similar. I think I have at least five different wires grounded to the back of the engine.

Thanks,
Jeff
