With the flow sensor harness connected to the ma-
chine and the ignition key in the ON position, slowly spin
the flowmeter rotor. The LED on the flowmeter should il-
luminate as a rotor magnet passes the flow sensor and
should go out as the next rotor magnet passes the sen-
sor.

make sure to alternately use both north and south poles
of the magnet.

If the flowmeter LED does not flash, remove rotor

and rotor shaft from sensor. With the flowmeter harness
connected to the machine and the ignition key in the ON
position, slowly pass alternate poles of a magnet past
the flow sensor. If the flowmeter LED flashes as the
magnet poles pass the sensor, replace the rotor and ro-
tor shaft. If the flowmeter LED does not flash as the mag-
net poles pass the sensor, replace the flow sensor.
