Checking relay power supply

• Remove the deadlock relay (2/115)
• Measure the voltage between terminal #5 in the relay base and ground.

  The voltmeter should read battery voltage

  HINT: If the value is OK but the fault remains, bridge between terminals #3 and #5 in the relay base to force a supply to the locking motor when continuing to take measurements
