the industrial bolster could be from late 50's thru 65.. etc..
the gm 10si is a common alt.
if it is the 3 wire.. #2 loops to charge stud.. #1 goes thru an indicator lamp like a 194 or similar and hooks to switched side of ignition. a diode could be used.. 1a 50piv minimum.. though more is better.. cathode (stripe ) toward #1
this provides ignition isolation...
I will have to digest all of that. It does have a two pronged plug on top. Someone had wired a gauge for it at one time as well.
