Afd hook up

I purchased an API alternator from mmi last year. I am interested in hooking up my afd from my perko switch. Can someone tell me exactly which connection on the alternator to use for this instillation.

Thanks. Az.

If you have a 1-wire alternator, it will take some doing to connect the AFD. There is no externally available field connection to use. This is one reason I like my combiner, the alternator goes straight to the battery and I can switch all my battery switches all day long with no ill effects on the alternator. A make-before-break switch can also accomplish this goal and they are readily available.
