Diagnostic Fault Information
Circuit/System Description
Each of the audio output channel circuits (+) and (-), at the radio and audio amplifier have a DC bias voltage that is one half of the battery voltage.
When using a DMM, each of the audio output channel circuits will measure approximately 6.5V DC. The audio being played on the system is
produced by a varying AC voltage that is centered around the DC bias voltage on the same circuit. The AC voltage is what causes the speaker cone
to move and produce sound. This voltage will vary depending on what type of audio is being listened to, talk or music, and type of music, as well as
the volume setting of the system. Low volume and talk settings will measure around 1V AC and less, where constant music may measure 3V AC
and slightly higher.
