SPEAKERS INOPERATIVE - ONE OR MORE

ONE OR ALL SPEAKERS INOPERATIVE

IMPORTANT: The following information lists the most probable cause of the concern to the least probable cause. If the list leads to the replacement of a component, always inspect for a poor connection before proceeding with replacement.

1. Speaker output open or shorted to ground. Test the appropriate speaker output circuits for an open or short to ground. A single speaker circuit shorted to ground can cause the radio to become inoperative.
2. No audio output from the radio. Test for a speaker circuit shorted to ground. If no problems found, test for any AC voltage between the appropriate speaker output circuits at the speaker harness connector, disconnected with the radio volume adjusted to an audible level. If AC voltage is present, replace the speaker. If no AC voltage is present, replace the radio.
