Prosport oil pressure gauge damaged?


Vertigo

Recommended Posts

Hi all. Ive just redone the power side wiring of my car. New relay panel and all. All three of my pod gauges draw from the same power wires. When I tested, I had forgotten to pin the ground for the gauges, and they didnt function obviously. When I figure out the issue, the AFR and boost gauges began working again, and the oil pressure gauge turned on and did its sweep, but then ramped to 100psi and stays there, even with the car off. No touching of the sense wire to the sender unit terminal or battery ground seems to result in any change.

Whats the default behaviour of these? I would expect it should show zero psi with the sense wire disconnected, but could be wrong. I suspect the gauge may have failed. What could be wrong?
