My voltmeter stopped working yesterday. 

I have done some checking and it looks like all my gauges are taking 22 - 24 volts. The alternator is producing 80+ volts while the battery is at 14.5 volts with the engine running and 12.5 with it off. 

Does this sound normal?  Is there some kind of resistor in the gauges to step down the voltage?  Could it be a diode?

Thank you for any help?

The coil type (early ones) is harder to find I think, the later ones are still available new and there are plenty available used on eBay. If you have a picture of the meter I may have a look at my collection of gauges. Problem is shipping costs though.
