How does the stator send current to the batteries?

[rsg1963]

The positive output of the rectifier/regulator feeds to the 3 pin plug on the left of the fuse box in the engine bay. Another wire comes out of the plug and goes to the starter relay where the battery wire is also connected. The start battery bank is the only one connected to the starter relay. The dvsr connects the start battery bank to the house bank when it receives +12vdc and the volatge is high enough on the start bank. Reinstalling the dvsr on the house bank and running a 8 awg wire off of where the start bank use to connect to either the start bank or the starter relay post where the start bank connects will correct the issue. I would also do the engine on only mod at this time.

@Mainah, this is super helpful and I get most of it, lol. Here is where it gets fuzzy:
"Reinstalling the dvsr on the house bank and running a 8 awg wire off of where the start bank use to connect to either the start bank or the starter relay post where the start bank connects will correct the issue. I would also do the engine on only mod at this time."
I am going to reinstall the DVSR to both BEP's this weekend if this is what you mean, and add a negative cable between both battery banks to complete the battery ground.
Also I am not sure what "the engine on only mod" is.

The stator generates a/c as the engine runs, the a/c is passed to the voltage rectifier that coverts it to 12vdc and supplies it to the battery

GIGGLE...YOU said...RECTIFIER..snicker.
