Matt,

The problem with the alternator supply is that if the alt. fails, you're dead in the water 'til you bypass the isolator. The oil pressure switch (from a Vega), on the other hand, only shuts down the pump when the engine initiates the shutdown.

Ken H.
Ken,
I like the idea and the Vega switch had the other function of of powering up the pump with ignition on. But that was 50 years ago and I really don't remember how it all worked and I don't have another place to add a pressure switch. All the regular pressure switches are normally open.
Anybody have any diagrams or part numbers?
Thanks
Matt
