I hooked it up as the manual shows. this is a single engine with gen vista 268
One positive on each battery from starter
one negative on each battery from ground
gen to one battery and amps to other battery
Boat has alway only had 2 batteries. Battery selector only has on, off and parallel, ships systems. While (on) it looks like being hooked up this way will charge both batteries.
It will charge both batteries while the switch is on. It will do this by running thru the battery isolator on the firewall right by where the step is. One battery will not drain the other thru this since it uses a one way diode style setup.
It should look like this

You have the same battery switch I have. The battery switch should only be in the "on" position while the engine is running. Put the switch into the off position when engine is not running to prevent any other parasitic draws from pulling it down and leaving you stranded.
I'm assuming your generator should be tied into your house bank and not your engine starter battery. When you refer to "amps" are you talking about the house bank or engine?
