Re: Changing '55 to Negative Ground System

Howard true, but all the gauges 51-56 use the exact same voltage regulator. (Packard P/N 458072).

Those regulators take in 6-15 volts and put out 5 volts, and because they are a simple chopper circuit, they are not sensitive to polarity.

So unless someone changed something, those "runtz" are not required on 51-54's when converting to 12v.
