B130C MERCURY MeaningThe trailer battery charge relay coil receives voltage from the Battery Junction Box (BJB) fuse when the ignition is in RUN. The BJB fuse supplies voltage to the Trailer Battery Charge Relay switch side at all times. The Body Control Module (BCM) controls the ground side for the battery charge relay coil.
The BCM provides ground for the trailer battery charge relay when the ignition is in RUN and the BCM determines that the battery voltage is not low. When the trailer battery charge relay is energized, the voltage is routed to the trailer tow connector.
