*The magnetic speed sensor indicates when ring geat teeth, or other ferrous projections, pass the tip of the sensor.

*Electrical impulses are induced within the coil and sent to the speed control unit.

*The signal from the magnetic speed sensor, teeth per second(HZ), is directly proportional to engine speed The magnetic speed sensor is mounted in the ring gear case or fly wheel 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 flast surface on which to anchor the locknut.

*With the engine stopped, screw the speed sensor in until it touches a gear tooth, then back it out 0.75 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 thespeed 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 need shielding if they are longer than 10 ft(3m), or if external interferenceis present.

Do not connect either of the speed sensor leads to anything but the speed control unit used.The shielcshould not be connected at the speed sensor end.
