OPERATION
The Power Door Locks are powered through Circuit Breaker 12.

The Door Lock Motors are normally grounded through both Door Lock Switches. When the Door Lock Switches are operated, voltage is applied through the Right and/or Left Lock Switches to the motors.

The 117 (PK/BK) and 118 (PK/O) circuits are the power and ground circuits of the Door Lock Motors. In the "LOCK" position, voltage is applied to one circuit and ground is applied to the other. Power and ground are reversed for the "UNLOCK" position
