DIAGNOSIS AND TESTING
Two or More Speakers Do Not Work
Balance and Fader Controls Adjusted to Mid-Position
It is unlikely that two speakers would be damaged at one time. The most
probable cause is in the radio chassis or wiring.
- Verify balance and fader controls are adjusted to mid-position.
- Inspect wiring connectors at rear of radio chassis for proper mating.
Verify electrical continuity of wiring between radio chassis connector and the
inoperative speaker connector using an ohmmeter.
- If wiring connections are properly mated and the condition persists,
remove radio chassis for service.
