Normal Operation
The audio unit transmits audio signals to the speakers as a fluctuating AC voltage. Each speaker has a signal and return circuit. The audio signals cause a corresponding vibration in the speaker cone, thus producing sound. The audio unit provides protection for shorts to ground and voltage.

Possible Causes
- Circuit 8-MD10 (WH/BK) open, short to ground or voltage
- Circuit 8-MD11 (WH/VT) open, short to ground or voltage
- Circuit 8-MD17 (WH/RD) open, short to ground or voltage
- Circuit 8-MD18 (WH) open, short to ground or voltage
- Circuit 8-MD28 (WH) open, short to ground or voltage
- Circuit 8-MD29 (WH/VT) open, short to ground or voltage
- Circuit 10-MD10 (GY/BK) open, short to ground or voltage
- Circuit 10-MD11 (GY/WH) open, short to ground or voltage
- Circuit 10-MD17 (GY/RD) open, short to ground or voltage
- Circuit 10-MD18 (GY) open, short to ground or voltage
- Circuit 10-MD28 (GY) open, short to ground or voltage
- Circuit 10-MD29 (GY/WH) open, short to ground or voltage
- Speaker(s)
