Normal Operation
Circuit 956 (OG/LG) is a constant battery B+ supply to the CD changer. Circuit 694 (BK/LG) is the CD changer ground circuit. Circuit 856 (VT) and circuit 833 (TN) are the audio control protocol (ACP) communication network circuits between the audio unit, CD changer, and the audio control protocol (ACP) module. Circuit 1068 (LG/BK) is the power on signal from the audio unit to the CD changer and the ACP module. Circuit 799 (OG/BK) and circuit 798 (LG/RD) are the left channel audio circuits between the CD changer and the audio unit. Circuit 832 (LB/PK) and circuit 690 (GY) are the right channel audio circuits between the CD changer and the audio unit.
