Engine Cooling Fan Switch
Theenginecoolingfanswitchisatwo(2)positionrocker
switch that is located on the outside of the control con-
sole (Fig. 30). The switch has a normal and a momen-
tary position.
6. If switch tests correctly and circuit problem still ex-
ists, check wire harness (see Electrical Schematics and
Wire Harness Drawings in Chapter 10 -- Foldout Draw-
ings).
The engine cooling fan switch is used as an input for the
TEC--5002 controller to allow the engine cooling fan to
run in the normal, automatic mode or in the manual re-
verse (momentary) direction.
7. After testing is completed, connect wire harness
connector to the switch.

in the Service and Repairs section of Chapter 7 -- Chas-

Testing
1.
Before disconnecting the engine cooling fan switch
for testing, the switch and its circuit wiring should be
tested as a TEC--5002 input with the Diagnostic Display
(see Diagnostic Display in the Troubleshooting section
of this chapter). If the Diagnostic Display verifies that
switch andcircuit wiring arefunctioning correctly,nofur-
ther switch testing is necessary. If, however, the Display
determines that the switch and circuit wiring are not
functioning correctly, proceed with test.

With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. The switch terminals are marked as
shown in Figure 31. The circuitry of the cooling fan
switch is shown in the chart below. Verify continuity be-
tween switch terminals.
