JMS, He may well have been referring to a Cutout Relay or perhaps a Voltage Regulator of which THERE CAN INDEED BE A DIFFERENCE AS YOU REFERRED TO IN POSITIVE VERSUS NEGATIVE GROUNDING !!!!! !!!!! On the later solid state two terminal diode "Cutout Relays" they can work at either Polarity buttttt ttttt t they simply have to be reverse wired if polarity is switched and many have the Pos or Neg directions right on the label and indeed the shop dude would need to know your configuration cuz it wont work if wired in reverse !! If its a full fledged 3 or 4 terminal Voltage Regulator instead of the 2 wire Cutout Relay, some are labeled for EITHER polarity, some are labeled specifically for Pos or Neg, so again the shop dude needs to know your configuration!! Its NOT the Generator that matters, they work regardless of polarity if polarized correct as described above, buttttt I certainly agree a Voltage Regulator and/or Cutout Relay can make a difference..... ... I doubt he converted 6 to 12, that can be done by changing out the gennys Field Coils, but that conversion requires the gennys changes plus the VR plus the ignition system (unless a magneto) so unless you requested it I dont see wwhy that would have taken place????? Fun discussion, yall take care John T
