John ,
That " wire with a coil around it " ain't a wire at all . It's a capillary
tube .
I believe it was filled with alcohol . The alcohol expands when it gets hot
and causes a mechanism inside the gauge to move the needle .
You can send your gauge to someone like PaloAlto Speedometer repair ,
or buy a working used gauge . Check the price both ways and decide what way
to go . Good Luck ,
