My oil level gauge seems to have stopped working. I know there is a lot of mis-understanding regarding how these work and I know the car should be hot and idling and on a level surface to get a reading.
What I know.
My in tank sender does read appropriate resistance values when moved manually (removed from tank) - so the sender is fine.
I get continuity when testing from engine bay connection to gauge, so its not open circuit.
Gauge never moves and always sits at the bottom, empty(not enough oil).
If I do not connect the oil gauge side of the gauge the fuel gauge does not work.
A new wire was run from fuel gauge to fuel level sensor to resolve an intermittent open circuit on fuel gauge, some time ago - could this be causing the problem?
Any ideas before I buy a second hand gauge which may or may not resolve the issue?
Any idea on how to trouble shoot the gauge itself?
