by the pump control switch located on the spray console.
The electric clutch is mounted on the pump drive gear-
box output shaft and is coupled to the spray pump. The
clutch engages when current is applied to the clutch.

Testing
1.
Locate clutch on pump drive gearbox shaft. Unplug
clutch connector from machine wire harness (Fig. 21).
NOTE: Prior to taking small resistance readings with a
digital multimeter, short the meter test leads together.
The meter will display a small resistance value (usually
0.5
ohms or less). This resistance is due to the internal
resistance of the meter and test leads. Subtract this val-
ue from from the measured value of the component you
are testing.
