[AT] Temperature gauge

[Gene Dotson]

    Most temperature gauges work by generating a microvolt current in the 
sensing bulb. This current is sent through the conductor to the indicating 
gauge on the panel. A very clean and positive ground to the panel is 
essential to get a proper reading. New paint, rust or corrosion can 
interrupt this current and not allow the indicator to work...
