AUDIO / VISUAL: AUDIO AND VISUAL SYSTEM: AMP Sound Signal Circuit between Radio Receiver Assembly and Stereo Component Tuner

AMP Sound Signal Circuit between Radio Receiver Assembly and Stereo Component Tuner

DESCRIPTION

The radio receiver sends sound signals to the stereo component amplifier. The amplifier then amplifies the signal, and the amplified signal is sent to the speakers.
If this circuit is open or shorted, no sound will come out of the speakers even if the amplifier and speakers are functioning properly.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK WIRE HARNESS (RADIO RECEIVER - STEREO COMPONENT AMPLIFIER)




(a) Disconnect the R3 receiver connector.
(b) Disconnect the S23 amplifier connector.
(c) Measure the resistance of the wire harness side connectors.
Standard resistance:






NG -- REPAIR OR REPLACE HARNESS AND CONNECTOR
