INSPECTION
1.
INSPECT CONTINUITY OF MOTOR RELAY CIRCUIT
(a)
Check there is continuity between terminals 9 and 10.
(b)
Check there is no continuity between terminals 7 and 8.
If continuity is not as specified, replace the relay.
2.
INSPECT OPERATION OF MOTOR RELAY CIRCUIT
(a)
Connect the positive (+) lead from the battery to terminal
10 and negative (
−
) lead to terminal 9.
(b)
Check there is continuity between terminals 7 and 8.
If operation is not as specified, replace the relay.
3.
INSPECT CONTINUITY OD SOLENOID RELAY CIR-
CUIT
(a)
Check there is continuity between terminals 1 and 9.
(b)
Check there is no continuity between terminals 2 and 5.
(c)
Connect the positive lead from the ohmmeter to terminal
5 and connect negative lead to terminal 4.
(d)
Check there is continuity between terminals.
(e)
Connect the 2 leads in reverse, and check that there is no
continuity between terminals.
If continuity is not as specified, replace the relay.
HINT:
For the different type ohmmeter, there is no continuity for step
(d), and there is continuity for step (e).
4.
INSPECT OPERATION OF SOLENOID RELAY CIR-
CUIT
(a)
Connect the positive (+) lead from the battery to terminal
1 and negative (
−
) lead to terminal 9.
(b)
Check there is continuity between terminal 2 and 6.
(c)
Check there is no continuity between terminals 2 and 6.
If operation is not as specified, replace the relay.
