Checking the relay supply

• Remove the relay for locking to the deadlock position (2/115).
• Measure the voltage between 5 in the relay socket and ground.

  The voltmeter should display battery voltage.

  HINT: If the value is OK but the fault still remains, link between 3 and 5 in the relay socket to "force-feed" the lock motor while continuing to test.
