just get a 12v regulator for the type generator that you have. why do they make a 12v regulator if a 6v would work by the same why do they make 12v generators if a 6v would work or you can do like a bunch of piddlers and screw around with the adjustments then burn something up and post on here i have a problem

Maybe, but a winding made for 12 volts will have many more turns. Running 12 volts on a 6 volt coil (as in the voltage regulator coil) will dissipate 4 times the planned heat and probably burn up the coil in a few hours if not sooner.

To raise the voltage you increase the spring tension on the voltage regulator coil. (The one with the finest wire in the winding).

12 volt regulators with the same connections as 6 volt regulators do exist.

The 6 volt generator will need to turn faster to charge at 12 volts than it takes to charge at 6 volts.

I work on a 55 chevy years ago that had boiled a new battery dry.No ammeter so I hooked one up.The 60 amp meter was pinned at 60 amps.I checked the generator tag and found it had a 6 volt generator on it.Chevy went to 12 volts in 55.This was at idle speed.12 volts on a 6 volt generator field will make it run full charge at low speed.You can put 12 volts on an alternator field and it will put out 110 volts dc.Better not have the output connected to the battery when you do this.You can run drills and skil saws with an alternator wired this way..
