Oil pressure

Hi Greg,

Try using a "master gauge" to get an accurate reading, to compare with your panel instrument.

Check - connections for a secure tight fit - wires for abrasion & security. This includes earth system.

You might also consider giving us more information eg what sort of gauge, aircraft, hrs, etc?

Temporarily connect a mechanical/Needle style Pressure gauge.
You may have an unstable pressure regulator like This One.

Great video Bill - Cure?

Ended up being a dodgy connection, thanks for the reply’s 

Fascinating description „unstable“ ;-)
