Hi Scott, and thanks for the compliment! This isnt my first foray into the world of electrical, but is my first time dealing with DC devices!
that switch panel is a circuit breaker/rocker switch panel that also includes a voltage gauge, a usb charger, and a vugarette lighter adapter. We don't really intend to use those chargers unless we are idiots and forget our portable chargers. There's one set of wires to run power to/from the switches, and a second set for the gauge and chargers.
My charger is a ProSport 20 plus, it plugs into an outlet on the AC system, which i only use by connecting to shore power.
the 1/2/B seitch is going to be a PITA - it will be on "1" when we want to start the engine, 2 when we want to use the electronics in the cabin, and essentially never on both. I just want it so that if something goes wrong with the start battery, I have the ability to start the motor from the cranking battery. I am unable to pull-start any devices due to shoulder issues, so that's not an acceptable "back up" for me.

Beth, you put together an excellent diagram. With Dave's comments and the reading that John recommended you will be on your way to having a first class understanding about how electrics is done on a boat. I have a few questions & comments:
- "Charges, Gauge" - I assume these are volt meters on your panel? They provide you with battery voltages for both the house and start battery? With added expense and installation complexity, you might consider a battery monitor for better understanding of the battery's condition.
- I might be missing something, but I don't see where your battery charger is introduced into the diagram. Typically, the charger is linked directly to the house bank (battery) - often via a positive buss that connects all charging sources (including alternator source). I understand your system is much simpler with an outboard. The charging current is then fed to the start battery via automatic charging relay (ACR) or echo charger, or simply by alternating the 1/2/B switch position appropriately.
- BTW, how do you use the 1/2/B switch? I won't assume that you don't know how to operate the switch, but if you aren't aware, the switch requires some knowledge about how it works. If you aren't operating the switch in the appropriate manner, you may not be loading or charging your batteries properly or you may be combining both batteries improperly. It would be helpful if you describe your typical routine as it relates to the switch.
