Re: Alternator disconnect
method of providing a alternator
disconnect (isolating) switch is to have the switch in the field circuit thus negating the need to worry about whether the ouput is open circuit or not.
I.E. they can be turned off when the engine is running.
EDIT: It would be very prudent for the OP to know exactly how the disconnect switches are wired before trying them while the engine is running!
