What is the transducer? What purpose does it hold? On this vehicle does it disassemble from the discharge line? Manual shows 2 electrical connectors both are lock safety type. 1 connector is obvious the 2nd connectes into a round tapered down type. Is the 2nd connector the transducer?
It is a vacuum valve used to transfer an electrical signal (this is its use in AC work but it probably has a multitude of uses)
