1. Check for continuitv between the terminals.
. There should be continuity between the A and B
terminals when power and ground are connect-
ed to the C and D terminals.
. There should be no continuity between the A
and B terminals when power is disconnected.

equivalent testerl, and turnthe selector switch to position'1 (starting).
2. Shift to neutral position, andstart the engine. Hold theengine at 3,000 rpm with noload until the radiator tancomes on, thon let it idle.3. Raise the engine sp€ed to2,000 rpm, and hold it there.
ls the voltage over 15.1 V?
Altsrnator/Rogulator Test-z:1. Release the accelerator pedal,
and let the engine idle.2, Make sure all accessories areturnod off. Turn the selectorswitch to position 2 (charging).
3. Remove the inductive pick-up,
and zero the ammeter.4. Place the inductive pick-up
over the battery ground cableso that the arrow points
toward the batterY negativeterminal,5. Raise the engine speed to2.000 rpm, and hold it there.
ls the voltage less than 13.5 V?
Ahelnstor/Regulator T$t-3iApply a load with the VAT-40until the battery voltage drops tobetween 12 - 13.5 V.

Fan Motor Test
Disconnect the 2P connector from the fan motor.
Test the motor by connecting battery power to the
B terminal, and ground to the A termlnal.
lf the fan motor fails to run smoothly, replace it.
NOTE: The illustration shows the radiator fan.
Radiator Fan Switch Test
NOTE: Bleed air from the cooling system after installing
the radiator fan switch (see section 10)
1. Remove the radiator fan switch from the thermostat
housing.
2. Suspend the radiator fan switch in a container ol
coolanl as shown.
Heat the coolant and check engine coolant tempera
ture with a thermometer.
Check the continuity between the A and B terminals
according to the table:

Actuatol Assembly Test
Disconnect the 4P connector from the actuator.
Check that the output linkage moves smoothly.
Connect battery power to the D terminal and ground
to the A terminal.
ACTUATOR
Check tor a clicking sound from the magnetic clutch.
and that the output linkage is locked. lf the outputlinkage is not locked, replace the actuator assembly.
Check the operation of the actuator moror In eacn
output linkage position according to the table (you
should be able to hear the motor).

Actuator Cable Adjustment
Check that the actuator cable operates smoothly
without binding or sticking.
Start the engine, and warm it up to normal operat-
ing temperature (radiator fans come on twice).
Measure how far the output linkage moves from thefully closed position. Free play should be 11 t 1,5mm (0.43 t 0.06 in).
FREE PLAY:1M.5 mm (0.43 1 0.06 in)
FULLY CLOSED POSITTON
4. lf the free play is not within specs, loosen the lock-
nut, and turn the adjusting nut as required.
NOTE: It necessary, check the throttle cable (see
section 1 1), then recheck the output linkage lreeplay.
5. Retighten the locknut, and recheck the free play.
