Phillip, the item you are describing as 1.5" in diameter and 2" across might be a ballast resistor. The one I installed when I converted my H to a 12 volt alternator system is like 3.5" long and around 1" wide made out of ceramic material with a wire resistor on the the back side. Those things can and do go out and will prevent battery current from being passed along to the distributor. You can jump across it if it is in fact a ballast resistor to see if your tractor will start. Don't run it very long in the jumped mode as it will tend to burn your points. The purpose of this resistor is to reduce the current to the coil to 6 volts from the 12 volt battery. If you have a meter you can do a quick check across this item and see what is going in and what if anything is coming out with the switch in the on position. The output should be attached to the "+" side of the coil with an alternator system. And yes a bad condensor can certainly be causing your problems. Hope this helps and good luck in finding your problem. Please post back and let us know what you find. Hal
