DESCRIPTION This circuit sends a signal to the stereo component amplifier assembly to mute noise. Because of that, the noise produced by changing the sound source ceases. If there is an open in the circuit, noise can be heard from the speakers when changing the sound source. If there is a short in the circuit, even though the stereo component amplifier assembly is functioning normally, no sound or only an extremely faint sound can be heard. WIRING DIAGRAM ![]() CAUTION / NOTICE / HINT NOTICE:
PROCEDURE
(a) Disconnect the G3 radio and display receiver assembly connector. (b) Disconnect the G8 stereo component amplifier assembly connector. (c) Measure the resistance according to the value(s) in the table below. Standard Resistance:
