Would like to bench test mine before refilling with oil. Wiring and the dash light were MIA when the tractor was received so no idea if sender works.
Understand a vacuum is created in the hydraulic system when the oil is cold which activates the sender which turns on the light. So, and this is a guess; in open air the sender will test open with no continuity between the chassis ground (or sender body) to wire terminal but under XX inches of vacuum, it closes providing a path to ground (or sender body)?
Received no response to this question in the Case/David Brown section.
