    once the high end rpm limit is reached and the switch is deactivated, does the RPM have drop below the activation RPM for the device to reactivate, or will the device reactivate if engines rpm is above the set low-end rpm?

    Asked by: Leviathan50
    It will reactivate once it drops below the set RPM.
