Speedo / Tach / Gauges: Fuel gauge and heat gauge 62 Lark

[Caligulette]

The fuel and heat gauges on my 1962 Lark don't work. The heat gauge needle sits at C, and the fuel gauge at E. I am not sure how to start trouble shooting on this?

Sorry to be so vague, and thanks in advance for any advice/insight.

First check the wiring. Make sure everything is hooked up right and has power. If that doesn't fix it,replace the sending units. The only thing left then is to replace the gauges.
