Gauge Mechanism

[chris_kucia]

Been thinking about coming up with my own replacement gauge faces, but I'm worried about losing the calibration. I'd have to remove the needles, pull the face, scan it, then put it all back together so I can drive while I make up new faces. Then I'd have to take it all apart again, install the faces, etc.

 

Was wondering if the gauges use magnetic cores, or stepper motors.

 

If magnetic, I was thinking I could put a known voltage through them and note the needle position. Then when I'm ready to put them back together, I could put the same voltage through them and put the needle in the same spot.

 

Wouldn't work if they're stepper motors.

 

 

Anyone know? It would save me taking them all apart.

 

Or if there are any other suggestions...

From reading other post concerning this very same issue I do believe they use stepper motors....do a search to confirm or else someone that has actually changed the gauge back panel can chime in.

Thanks. I had done a search for all the different ways to say "gauge calibration" and didn't find anything. Searching on "stepper" pulled up a bunch.
