Motor Relay Continuity Check:

Motor Relay Operation Check:

Solenoid Relay Circuit Check:

Solenoid Relay Operation Check:

1. Inspect continuity of motor relay circuit.
a. Check for continuity between terminals 9 and 10.
b. Check for no continuity between terminals 7 and 8.
NOTE: If relay continuity is not as specified, replace the relay.
2. Inspect operation of motor relay circuit.
a. Connect the positive (+) lead from the battery to terminals 10 and negative (-) lead to terminal 9.
b. Check for continuity between terminals 7 and 8.
NOTE: If relay operation is not as specified, replace the relay.
3. Inspect continuity of solenoid relay circuit.
a. Check for continuity between terminals 1 and 9.
b. Check for 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. Check for continuity between terminals.
d. Connect the two leads in reverse, and check for no continuity between terminals.
4. Inspect operation of solenoid relay circuit
a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 9.
b. Check for continuity between terminal 2 and 5.
c. Check for no continuity between terminal 2 and 6.
NOTE: If relay operation is not as specified, replace the relay.
