Answer: If you remove the cap, and place a plastic knife or piece of a butter tub lid cut to a strip, between the points so they are not closed. You should find 12v on both small coil terminals (resistors do not make a difference on this test). If no voltage on the switch side of the coil (should be the positive side in a alternator conversion) there is a supply side issue from the ignition switch circuit. If the distributor side of the coil has no voltage and If the switch side reads resistor voltage ~6 volts, the points are shorted to ground (possible where the terminal goes through the dist. housing. or points spring. The condenser could also be defective and shorted. If voltage on both sides. pull out the plastic from between the points and recheck the voltage. 4 cylinder engines almost always stop with the points closed. if they are open with no plastic between, and the 4 lobe point cam is not on a lobe, the points are not adjusted (.020" on a cam bump) if closed and still same volts on both sides, the points may have a film of insulating goo on them from the factory. A tiny bit of carb cleaner on the corner of a dollar bill will wipe it off. If still voltage on both sides of the coil, the wire to the distributor may be bad. Jim

Today's Featured Article - An AC Model M Crawler - by Anthony West. Neil Atkins is a man in his late thirties, a mild and patient character who talks fondly of his farming heritage. He farms around a hundred and fifty acres of arable land, in a village called Southam, located just outside Leamington Spa in Warwickshire. The soil is a rich dark brown and is well looked after. unlike some areas in the midlands it is also fairly flat, broken only by hedgerows and the occasional valley and brook. A copse of wildbreaking silver birch and oak trees surround the top si
