OP, you have a "bird" system which uses the same solenoid for boost, shore charging of the engine batteries, and alternator charging of both. On shore power when the engine batteries get aprox 0.5V lower the BigBoy engages and charges the engine batteries
I recently replace my NoCold 1200 with a home refer and posted my DIY project here. I created a separate battery bank, transfer switch, 1000W PSW inverter, and a 100A charger system for it.
I added a cable and 200A switch from my house batteries to the new battery bank so by turning the switch on, the refer batteries will be charged by the alternator going down the road. The extra 8 amps is well within my 200 amp alternator capabilities although I do use my generator to charge my batteries before getting on the road after boondocking.
