THERMOST A TIC SWITCH
The cooling fan motor is actuated by the thermo-
satic switch located in lower the radiator.
If the fan motor does not start, disconnect the
switch coupler from the thermostatic switch and
short coupler terminals together with a jumper wire
as shown.
Turn the ignition switch on.
The cooling fan motor should start running.
If it does not start, check for battery voltage from
the black lead (positive) to black/blue (negative) of
the fan motor coupler.
If there is no voltage, check for a blown or faulty
fuse, loose terminals or connectors, or an open
circuit.
If it starts, inspect the fan thermostatic switch as
follows:
Suspend the switch in a pan of coolant (50-50
mixture) and check the temperatures at which the
switch opens and closes. Make sure that there is no
switch continuity with room temperature and
gradually raise the coolant temperature. The switch
should be continuity (close) at 98-102°C (208-
215°F).
NOTE:
Keep temperature for 3 minutes before
testing continuity. A sudden change of
temperatu re will cause error of tempera-
ture reading between the thermometer and
the switch.
Do not let the thermometer or switch
touch the pan as it will give a fales reading.
Soak the switch in coolant up to its
threads.
TACHOMETER
If the tachometer does not work properly, replace
the 1-3 spark unit with a new one and recheck the
operation.
If the problem still appears, replace the spark unit
with the original one and replace the tachometer.
