The "switch" is a circuit breaker on the output side of the 1-ALL-2 switch.
Turning of the key can cause destructive inductive kick to reverse bias the
rectifying diodes in the alternator. Cheap low power alternators are more
likely to experience diode destruction. You also get a bigger kick wh
A followup on Josh’s post:
1. A couple of times I have accidentally turned the key switch off while the
engine was running and my brain was elsewhere. I immediately turned it back on
again. I have noticed any problems resulting from this, but I don’t know what

So if I understand this correctly it isn’t a 2-way street. When a charging
source is connected to the house bank the rise in voltage will close the
solenoid and the two bank are now joined. The
The 1-All-2 typically is a make-before-break type switch so that the circuit
will never see a alternator-diode-frying open circuit. That being said I
understand it isn’t best practice as arcing occurs and degrades the switch
same reason it’s best not to leave circuits turned on (e.g. cabin

It's not "smart" it always starts charging the "primary" bank first. Once
the primary battery is full (ish) it combines the second battery.

Easy answer, disconnect the second bank from the charger.

Thanks Gary. I get that and I suppose it certainly simplifies the wiring - you
essentially have one bank for charging purposes. No opinion at this point
although I do feel silly having spent the last year dutifully switching between
1-both -2. I assume it’s just a relay that connects the circ
Hi John,
I've had ACRs on my boats for the last 15 years and I think they are
one of the best upgrades you can do. When I bought "Kaylarah" (formerly
"High Maintenance",adding and ACR was one of my first upgrades. They are
usually wired to charge the house bank first, then the start bank. I
So while connecting batteries today i discovered, to my surprise, that Paws has
an automatic charging relay between the two battery banks. Yes, I’m still
learning this boat. So as I understand it, once voltage hits 13.6 volts (or
13.0 for 2 minutes) the relay will automatically combine the two
