It's never worked since I've had it.
Tried shorting the transducer still nothing. So I've checked and have earth at the transducer.
So I've popped out the gauge. It has 3 connections marked up
T- guess this is transducer?
14.4v- so I guess should be live?
And the other I guess is earth.
Checked and earth works
But when I checked the continuity from the transducer it was connected to the 14.4v terminal.
I've swiped them over and still nothing but if I short it now it jumps to the top of the scale and stays there until I switch the car off?????
Confused now
