The magnetic speed sensor is mounted in the ring gear case or flywheel bell housing of the engine.
The threaded hole for the speed sensor should be perpendicular to the centerline of the crankshaft
and centered over the ring gear teeth. A spot face should be present to provide a flat surface on which
to anchor the locknut. With the engine stopped, screw the speed senor in until it touches a gear tooth,
then back it out 3/4 of a turn and secure it with the locknut. Any ferrous gear may be used as long as the
frequency and amplitude of the resulting signal meet the speed control unit specifications The wire leads
should be twisted for their entire length from the magnetic speed sensor to the control unit.
The leads may needshielding if they are longer than 10 ft. (3m), or if external interference is present.
