HEI module going spastic?

With engine off, set the crank at the initial timing for #1. Then check the pick and reluctor, and rotor positions. If the rotor points to #1, and pickup pole is near trailing edge of reluctor tooth the pickup phase is correct. If the rotor is 1/2 way between terminals, and the gap between reluctor teeth are aligned with pickup pole, then swap pickup wires, and re-time engine.
