4. Inspect for smooth motion to OFF position. Replace if not found.

5. Inspect weather boot (6 or 18) for damage or wear. Replace if necessary.

Connector J2 (17)

1. Inspect wiring for breaks, fraying, discoloration, or damage. Replace if found.

2. Inspect soldered connections for breaks or damage. Repair or replace if found.

3. Inspect pins for bending or corrosion. Straighten bent pins if possible. Clean minor corrosion. Replace if necessary.

4. Inspect electrical contacts for corrosion. Replace or clean as necessary.

TEST

Circuit Breaker (9 or 10)

1. Tag and disconnect leads.

2. On the S9160-18K-3 units, check for continuity in ON position between contacts A1 and B1; A2 and B2; A3 and

B3. Continuity should exist. No continuity should exist between these contacts in the OFF position.

3. On the S9150-18K-1 units, check for continuity in the ON position between contacts A1 and B1; A2 and B2.

Continuity should exist. No continuity should exist between these contacts in the OFF position.

4. Replace if fails test.

Wiring and Connectors

1. Leave soldered connections secure.

2. Check for continuity by touching the test probes of a multimeter set on low-resistance range, to the ends of wire

and/or the corresponding pin of connector. See WP 0038 00, schematic diagram.

3. Replace pins and wire if not found.

REPAIR

NOTE

Repair of circuit breaker and/or connector J2 is by replacement of components.

Circuit Breaker (9 or 10)

1. Verify labels with wire list (WP 0038 00) and disconnect leads from the circuit breaker. These are terminal lugs.

Leave soldered connections secure to connector.

2. Remove screws (7) and flat washers (8) securing circuit breaker (9 or 10) and weather boot (6 or 18) to mounting

bracket (3 or 4).

4. Slide circuit breaker (9 or 10) and weather boot (6 or 18) through back of mounting bracket (3 or 4) and remove and

replace.
