On the three brush generators that used a cutout relay versus a Voltge Regulator, the light switch was dual purpose cuz in addition to lights it also allowed for Low or High Charge settings andddddddddd it has a certain ohms value resistor to limit field current when in LOW charge position (it wires to the gennys FLD post). One possible problem is the resistor may be of a different value depending on if its a 6 or 12 volt generator soooooooooo Im not even sure they made an M switch for 12 volts but if so insure the switches resistor is the right value. If not she can still work n charge but the Low charge rate may not be what its supposed to be i.e. if the resistor is wrong value the gennys Fields may draw too little or too much current. Of course, the lights dont matter either switch should still work fine far as lights are concerned, its just that Low/High charge resistor value may be different (if they even make one for 12 volts at all???)....... In high charge the gennys field is dead ground NO resistor used so it wouldnt make any difference in that case and a lot of time people used the High charge switch setting anyway so theres no problem if a 6 or 12 volt in that scenario. If shes converetd to a full fledged Voltage Regulator then the light switch no longer wires to gennys FLD post and the light switch will still work regardless if 6 or 12......

Today's Featured Article - What Oil Should I Use? - by Francis Robinson. I keep seein this question pop up over and over again in discussion groups all over the web. As with many things there are often several right answers and a few wrong ones. Some purist I'm sure will disagree to no end with what I will tell you but most of us out here in the real world don't really care do we ? Some of them only bring their noses down out of the air long enough to look down them anyway. If you are like me you are only doing this old tractor stuff because you enjoy it. You
