2) Test the cooling fan motor for load current with an
ammeter connected as shown in the figure.
If the fan motor does not turn, replace the cooling fan
assembly with a new one. Refer to "Radiator /
Cooling Fan Motor Removal and Installation
(Page 1F-5)".
NOTE
• When making this test, it is not necessary
to remove the cooling fan.
• The voltmeter is for making sure that the
battery applies 12 V to the motor. With the
fan motor with electric motor fan running
at full speed, the ammeter should be
indicating not more than 5 A.
