Verifying Proper Power Cable Installation:
Remove the power connector from the back of the vault and refer to the diagram below.
Using a voltmeter insert the positive (red) lead inside pin 1 and the negative lead (black) inside pin 2. The voltmeter should read positive 12 volts.
Next insert the positive lead (red) inside pin 4 and the negative (black) lead inside pin 3. The voltmeter should read positive 12 volts.
If both tests read positive 12 volts the power cable is properly installed.
If either or both of the tests did NOT read positive 12 volts, check to make sure the red wire is connected to the positive 12 volt side of the battery and that the green and black wires are connected together to the chassis ground.
