Suzuki DF150 & DF175 battery-isolator

Read this and it was the first time I've heard this benefit in our outboard. Can someone w/ electrical smarts explain how this would work. Would I have to have my battery switch to "both", in order to take advantage of this?

It sounds like an automatic charging relay (ACR) comes standard with the motor.

There is an optional second charge output on the motor, although I don't think we've ever utilized it as the output isn't very great.

I believe that all of the Suzuki 150 and 175 have that second output. My understanding is that is is a diode type of isolator. I do not know the capacity, but I thought it was more than a trickle charge.

You can charge both batteries at once. One is the battery connected to the "start" circuit. There is a connector (white I believe) under the cowl for the second charging circuit. The PDF brochure for the 150/175 shows that there are two regulators in the circuit--thus I suspect that the second circuit is possible of the full 44 amp output.

Interesting.
