I recently purchased a 1954 GMC 1/2-ton PU and apparently this truck was converted to a 12 volt generator system, but I am not sure if it was done entirely correct. The part I am unsure about is whether they put voltage reducers in for the all the gauges and the for the heavy duty accessories like the heater. Is there a way to tell if there is a voltage reducer installed and where would it likely be installed. My gas gauge does not currently work and I was wondering if they broke this gauge by not installing a voltage reducer when they converted it to 12 volts. Any help on this issue would be much appreciated. Thanks.
