Stop, backup, regroup....Mike, if those windings have a common ground (which I'm beginning to think NOT) that would mean that the primary (12 volt) winding is ALWAYS hot! How is that possible? The current cannot be induced in the secondary windings until the magnetic field produced on the 12 volt primary is switched on/off repeatedly by the opening/closing of the points. Hence I'm back to my thought that the primary winding is electrically isolated from the coil case and the two small posts on the coil are insulated. Further evidenced by the fact that a coil wired backwards will work, albeit not as well. If it's the secondary winding that is electrically isolated through the points (which I doubt) that little wire from the points (in the distributor) to the coil would have to be as thick and heavily insulated as the one from the top of the coil to the distributor cap. I think not. How 'bout it ltf, is it the secondary winding (high voltage) that is case grounded to the frame? Is the primary winding, in fact, electrically isolated from ground until the points close? Inquiring minds want to know....;-) Gadget

Harvestin Hay: The Early Years (Part 2) - by Pat Browning. The summer of 1950 was the start of a new era in farming for our family. I was thirteen, and Kathy (my oldest sister) was seven. At this age, I believed tractor farming was the only way, hot stuff -- and given a chance I probably would have used the tractor, Dad's first, a 1936 Model "A" John Deere, to go bring in the cows! And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
