Checking resistance must be done with the wiring disconnected, and no voltage applied. If you disconnect the wire from the coil (-) terminal and turn the engine until the points close, there should be virtually no resistance from that wire to ground, less than one ohm. I have no idea what the coil primary resistance should be, fro the coil + terminal to - with wires disconnected from both terminals. These checks just aren't something that's done routinely. If you're getting enough voltage at the - terminal with the ignition on and points closed to make a test light burn at all, the points have way too much resistance. Change 'em! Jerry
