Rally Dash Conversion Question

Agree with the 12 volts probably cooking them. I’d do a resistance check to verify. Gauges are reproduced but they are pricey.

May be others that sell them. So as with any repoped parts shop around. If one sells them others do and they’re probably all from same source.
