Dozer wiring diagram

Ken, I remember looking into just such a device and remember finding one. For the life of me I can't seem to recall who made it but I will go through my archived information and see if I can track it down. It did exactly what you described, it would only turn the pump on when the valve servos were activated. It was quite the gizmo and I am sure saved a ton of wear and tear on the pump system and battery.

I have a relay that runs an air pump to build air and then it will dump the air. Ed
