INSPECT NO.1 COOLING FAN RELAY (”FAN NO.1”)
A. Inspect relay continuity
(a) Using an ohmmeter, check that there is continuity
between terminals 1 and 2.
(b) Check that there is continuity between terminals 3 and
4.
If continuity is not as specified, replace the relay.
B. Inspect relay operation
(a) Apply battery voltage across terminal 1 and 2.
(b) Using an ohmmeter, check that there is no continuity
between terminals 3 and 4.
If operation is not as specified, replace the relay.
