ABSTRACT:
A pulse generator unit for a fuel pump register employs a pulser shaft driven by a pulser drive gear rotatable with a lowest order counter wheel. A permanent magnetic means at the end of the pulser shaft rotates and actuates a reed switch to produce a pulse train having pulses indicative of rotation of the counter wheel. A ratchet clutch assembly is employed to selectively permit rotation of the pulser shaft in a counting direction and a resetting direction.
