INSPECTION OF CONTROL RELAYS
1. REMOVE CONTROL RELAYS
Remove the two control relays from the actuator.
2. INSPECT PUMP MOTOR RELAY CONTINUITY
(a) Check that there is continuity between terminals 1 and 2.
(b) Check that there is no continuity between terminals 3 and 4.
(c) Check that there is no continuity between terminals 1 and 4.
If continuity is not as specified, replace the relay.
3. INSPECT PUMP MOTOR RELAY OPERATION
(a) Apply battery voltage to terminals 1 and 2.
(b) Check that there is continuity between terminals 3 and 4.
(c) Check that there is no continuity between terminals 1 and 4.
If operation is not as specified, replace the relay.
4. INSPECT SOLENOID RELAY CONTINUITY
(a) Check that there is continuity between terminals 1 and 3.
(b) Check that there is continuity between terminals 3 and 4.
(c) Check that there is no continuity between terminals 4 and 5.
If continuity is not as specified, replace the relay.
5. INSPECT SOLENOID RELAY OPERATION
(a) Apply battery voltage to terminals 1 and 3.
(b) Check that there is continuity between terminals 4 and 5.
(c) Check that there is no continuity between terminals 2 and 4.
If operation is not as specified, replace the relay.
6. INSTALL TWO CONTROL RELAYS
