Welllllllll the shop CAN go ahead and Polarize the Genny for Pos or Neg Ground as you wish, but Id just polarize it myself once its installed to be safe n sure but BEFORE you start it.
Change the lights to 12 volts.
If its a coil ignition you can:
EITHER add a series external voltage dropping (12 to 6) Ballast Resistor AFTER the Ignition Switch but before/ahead of the coil OR ELSE buy a new full true 12 volt coil NO ballast required.
Wire the coil to match the polarity i.e. for Pos grnd the coils lil - terminal gets ign switched voltage while its lil + wires to distributor but opposote that for Neg ground.
If it has an ammeter and you change polarity from original the leads need swapped or it will register bass ackwards
