Normal Operation
When the ignition switch is in the RUN or ACCESSORY position, voltage is supplied to the refrigerator relay coil from Smart Junction Box (SJB) fuse 34 (5A), through circuit CBP34 (VT/BN). The refrigerator relay coil is grounded at all times through circuit GD120 (BK/GN). High current voltage is supplied to the refrigerator relay from Battery Junction Box (BJB) fuse 25 (15A), through circuit SBB25 (RD). When the refrigerator relay is activated, voltage is supplied to the refrigerator through circuit CBB25 (WH/OG). The refrigerator is grounded through circuit GD149 (BK/GY).
