Good news Andy, The solution is at hand. The points open and close breaking the connection to ground. If the distributor side of the coil stays with voltage when the points are closed, the distributor is not doing that make and break action. The coil is a high voltage transformer. It converts a rapidly collapsing low voltage current into a spark jumping 10 to 25000 volts. The primary coil winding is turned on when the points close. This is when that rubbing block is between cam lobes in the distributor. It is called dwell. It is measured in degrees. A current flows through the coil building up magnetism in a field that includes the secondary (high voltage) windings. When the points break (open) the primary voltage stops flowing and the magnetic field collapses. The condenser in the circuit acts like a shock absorber and reduces the arcing on the points, as well as resonating with the coil sustaining the spark. The collapsing magnetism creates the dramatic voltage. This voltage continues to increase until the spark can breakdown the resistance of the spark plug gap. It then discharges across the gap igniting the fuel and air. Yours is not connected. With the cap off, points closed, the tractor in Neutral, and the ignition on, test for voltage at the terminal on the side of the distributor. There should be none. If there is then probe inside to see if there is voltage at the nut and washer that holds the point conductor and condenser conductor and point spring. If there is voltage there (there should not be) test the movable point if there is voltage there, test the stationary point. There should not be voltage there either. Fixing is a function of making sure there is no crud or dirt in the points holding them apart. Nor disconnected components making an open circuit when it should be closed through the closed points. Filing or sanding then cleaning the points may be all it needs, but a broken wire is also a possibility. Jim

Today's Featured Article - The Great Escape - by Dave Hollrah. It all began Monday with a little baling of second crop on the lake shore field, and as I drove out past my sister and her hubby's place, this small calling sound could be heard from the general direction of their manure pile. Out of the yard, over the cows and bale piles, through the dozer piles, poplars, and brush, out onto the ditch grade road, past the noisy 6.2 diesel engine pulling my well traveled Suburban along. Well it sure didn't take me long to figure out what it was because I alrea
