Gauge Cluster Issues/IVR

[QUOTE="Mattax, post: 1972858065, member: 29156
The only hiccup was the temperature gauge which hung at the 1/6 mark for a while and then suddenly clicked to 1/2 scale. I'm guessing that would have to be a mechanical hangup to jump like that.[/QUOTE]
Yep, That's why I had to have a decade resistance box to service these gauges. I needed to see a somewhat fluid like movement when needle travels up and down with a wide variety of resistance values thrown at them. I never sit in the car and watch my gauge needles go home at switch off but I knew a customer might. Believe me it aint easy. This needle is on the post in 2 places and its too tender too. Just a little push can distort alignment of those 2 holes or more correctly, the parallel of those 2 planes. Where needle is attached to bimetal is a steel shaft sliding and wearing the slot in aluminum. Multiple places to develop a hitch in its giddy up.
Do you see any dust/debris in there?
