On topic in that I have swapped AGM's for lithium house batteries. Now I can't start my generator.
I have all my new batteries in the forward battery compartment.

I seam to have 100% functionality of the house side of things. Low volt lights, air compressor, inverter/battery circuits.

I don't have generator start.



Near as I can tell at this point the house batterie positive makes a direct shot to the inverter. In the same location as the inverter is a low volt buss panel, mounted high on the bulkhead between the bays. (see photo) On the main positive bus of that panel I had 3- 4/0 cables landing on it. I was not able to identify their other end of 2. One of the three has continuity to the house battery main bus positive, in the battery compartment, it also had battery equivalent voltage to ground.  

My method for finding both ends of any one cable is to attach a wire to one end with my volt meter to the other, set to ohms and then go around the coach looking for continuity. Is that mythology correct? 

It didn't occur to me until this morning that the generator might be taking it's power from that bus panel.  

I have disconnected many 4/0 battery cables around the coach. The isolator has had the house side disconnected. The merge solenoid has had the house side disconnected. I have abandoned in place all battery cables that I have disconnected. They have either been disconnected at both ends or had the visible end insolated. 



So I think my marching order need to find both ends of all these cables as Richard already told me. 

Is it reasonable for me to think I'll find an existing path of cables from the generator starter to the engine start batteries? 



Thanks.

TJ, 
I don't know about your lithium setup, but if you isolated it like I did because I went to a 48v house system you can connect the generator to the house batteries at the isolator after you know which wires go to where.
I believe on my coach the generator lead was found in the little fuse box above the original inverter.
My 48v system charges the engine 12v that now powers all 12v loads
