Jeff........both the original 6-volt squarecan coil and the modern 12V-square can coil need the "infamous ballast resistor" (mounted on the backside of the dash panel under the ammeter) NO ARGUE!!! To use the original 6-volt square can coil on 12-volts, you also need a 12-to-6V converting resistor of 2.5-ohms and 50-watts. (these are electrical specifications) Most tractor parts stores do NOT sell the correct 2.5-ohm converting resistor. They try to sell you the 8NE10306 (YT claims it is 3-ohms, which is close) It will work but causes weaker sparkies. One of the reasons to convert to 12V is faster starting hotter sparkies and quicker spinning of the 6-volt starter motor. (NO, 12-volts does NOT hurt yer 6-volt starter motor) Remember to also change yer headlites to 12-volt bulbs. Yer distributor points and condenser are good for about 200-volts so no worry there. .......Dell, a 12-volt advocate that knows 8-ways to convert to 12-volts and they all work the first time

Today's Featured Article - Fire in the Field A hay fire is no laughing matter-well, maybe one was! And a good life-lesson, too. Following World War II many farm boys returned home both older and wiser. One such man was my employer the summer I was sixteen. He was a farmer by birth and a farmer by choice, and like many returning soldiers, he was our silent hero: without medals or decorations, but with a certain ability to survive. It was on his farm that I learned to use the combination hand clutch and brake on a John D
