Interesting. Not seeing the rest of the installation, I can’t comment. All of the systems I’ve seen have been as you describe your older boats.I did a rudimentary experiment with my batteries and switches. (I posted a video of it, but I'm embarrassed of my rambling and stuttering to post it! Mel Tillis and I share similar genes! ).
We have 'that' Guest battery switch, (similar to the Perko) that came with every boat I have owned for the past 40+ years.
With the engine running, and with the Guest Switch set on Battery #1, I checked the charge voltage on each battery. I won't remember the exact numbers, but BOTH batteries were receiving over 14 volts charge from the engine alternator... With the Guest Switch on Battery #2, same thing; BOTH batteries were receiving charge from the engine alternator. (I was checking the voltage with a top-line Fluke Volt/Amp/Ohm meter). This did NOT occur on any of our previous boats. On those, if you wanted to charge both batteries while the engine was running, you had to have the Battery Switch on 'Both'. The newest of those boats was built in 1986. The point I'm trying to make is that with newer boats/newer technology, you do not have to have the Battery Switch on 'Both' for both batteries to receive charge from the engine. It seem on our Parker, each battery is receiving the charge it needs, as needed.
My guess is new technology with DVSR, VSR and/or the 'Battery-Isolator' has something to do with this...
Might have to do some digging in manufacture’s literature for the newer switches. See what I can find!
