Not sure, most people use the automatic type isolator. I'm sure it will come with some wiring directions.
yea 1 to pos and 2 to pos and 3 is common
just wondering if i hook up stator wire to common on switch, will it charge the battery by switch location?
I have mine set up through a battery switch to terminal posts. The stator will charge the battery that you have selected, I have not installed my dual volt meter yet so I pick and choose which battery I run and charge depending what I've been using. If you are not using identical batteries, do not keep the switch on 1+2 position, that would be for emergency starting only and then immediately switch to one or the other
just got mine all hooked together charges it fine
