1...Check resistance of the pickup. I've forgotten, I usually compare to a spare to remind me
2....Check for continuity from the pickup wires to ground.........should be open
3....Crank the engine or spin the dist with your meter hooked to the pickup on low AC volts. Should generate about 1V AC
4....Unhook the dist. and take hold of the engine bay side of the connector. With key in "run" tap the exposed terminal of the connector to ground. Should make a hot "snap" spark each time.
