temp gauge internals

[Konstantin Bogach]

Hi listers.

I decided to forward back to the list the message I sent ealier under
different subject because I suspect that many people found that thread
not interesting and could just skip it.

The reason I do that is I realy very curious how the gauge works. I
would appreciate if someone comment on it.

Thanks. 
Konstantin Bogach.

I was inside the temp gauge.  Definitly somebody played with needle. And
I
know who it was - my 2 years old daughter.  I took her seconds before
she lost
interest. Nobody saw it.
It is fixed now.. By the way I can explain what I saw just as
bimetallicU-shaped strip with wound wire around one leg which servse as
a
heater, I think. But I never heard about such kind of gauge
construction.
Heater inside the gauge? Hmm.  From other hand I can not find any other
physics inside the gauge.  If I am wrong  then I overestimated my
knowledge of
physics.  I would appreciate if someone prove it in this case.

Speedo needle was overturn and not being able to take the needle off I
just
forced it in oposite direction and it rotated on the shaft. Now it
starts on 0
and goes all the way up.

Sorry for panic posts.
