  4. Inspect the connector and socket terminals to be sure they are all making good contact.
    • If the terminals are bent, loose or corroded, repair them as necessary and recheck the system.
    • If the terminals look OK, go to step  5.
  5. With the connector still disconnected, do these input tests at the connector.
    • If any test indicates a problem, find and correct the cause, then recheck the system.
