Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

AUDIO / VIDEO: AUDIO AND VISUAL SYSTEM: Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

Sound Signal Circuit between Radio Receiver and Stereo Component Amplifier

DESCRIPTION

The radio receiver assembly sends a sound signal to the stereo component amplifier assembly through this circuit.
The sound signal that has been sent is amplified by the stereo component amplifier assembly, and then is sent to the speakers.
If there is an open or short in the circuit, sound cannot be heard from the speakers even if there is no malfunction in the stereo component amplifier assembly or speakers.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (RADIO RECEIVER ASSEMBLY - STEREO COMPONENT AMPLIFIER)





(a) Disconnect the I4 radio receiver assembly connector.
(b) Disconnect the I17 stereo component amplifier assembly connector.
(c) Measure the resistance according to the value(s) in the table below.

Standard Resistance:





(d) Reconnect the radio receiver assembly connector.
(e) Reconnect the stereo component amplifier assembly connector.

NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- PROCEED TO NEXT CIRCUIT INSPECTION SHOWN IN PROBLEM SYMPTOMS TABLE
