Thanks guys.

I remembered the starter is connected is connected via a solenoid. Then found the cable leading from the low volt bus panel above the inverter that runs all the way back to the rear engine electrical box. I used the one side of the merge solenoid as a bus to connect everything at that end. I used a bronze bolt to connect the genny cable to the start battery cable. a bit of shrink tube and tape should be good until I figure out a better solution. I think another bus terminal post or two is in order. Generator is running and stopping on command.



EDIT:

I did a volt and amp check on both battery banks. It's clear the genset is charging the chassis battery.

Again thanks for having this forum here. Thanks to all the folks that share their wisdom.
