I kind of know what this is but I'm not sure why it's important...
The start battery
leads into it
It then feeds the engine
It loops over to the house bank
There is a remote
switch. You can clearly hear a solenoid click when activating the switch.
My continuity meter says that in one switch position, it connects the start battery
. In the other switch position it connects the house bank.
I thought it would connect both start & house batteries but apparently it does not.
So what is the importance of this vs. a 1/2/both selector switch?
Is there some other feature not apparent to me?
