My 87 came with 2 8Ds for chassis & 4 6v golf cart for house. I changed to 2 8Ds for house & kept the the 8Ds for chassis so that they would charge evenly when all connected together.

I have been very pleased. The redundancy is nice.

I also replaced all of the battery cables with 0000 tin plated marine cable. I bought a hydraulic crimper so I could make my own cables.

As for a wiring diagram, I don't have one - but I will attempt to describe . . . . .

-Hot from house battery bank goes to one terminal of the house disconnect switch.
-From the other terminal of the house disconnect switch, 3 cables are connected - one to a big terminal on the merge solenoid, one to the house load distribution, & one to the generator (for starting)

-Hot from chassis battery bank goes to one terminal of the chassis disconnect switch.
-From the other terminal of the chassis disconnect switch, 2 cables are connected - one to the other big terminal on the merge solenoid, the other to the chassis load distribution & starter

For the merge solenoid to work, at least one battery bank must have a sufficient charge to energize the solenoid coil.

I also replaced the disconnect switches with higher amp rated switches with larger terminals (Cole Hersee #75908 300A continuous, 2000A intermittent)
