Question Re: regulator in alternator M25XPB - connection to battery?

Thank you guys.
So I am still trying to understand the electrical system on board and how the alternator fits in. The wiring of my battery switch (see below) has only one positive large diameter wire (2 AWG) running to the engine. So could it be that this wire is used to start the engine and after that to sense and charge the batteries from the alternator (green dotted line). Thanks a lot for your input.
