1. INSPECT RELAY CONTINUITY
(a) Using an ohmmeter, check that there is continuity between
terminals 1 and 3.
(b) Check that there is no continuity between terminals 2
and 4.
If continuity is not as specified, replace the relay.
2. INSPECT RELAY OPERATION
(a) Apply battery voltage across terminals 1 and 3.
(b) Using an ohmmeter, check that there is continuity between
terminals 2 and 4.
If operation is not as specified, replace the relay.
