Speakers Inoperative - One or More

SPEAKERS INOPERATIVE - ONE OR MORE

ALL SPEAKERS INOPERATIVE WITH REMOTE AMPLIFIER - UZ6

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

1. Test the battery and ground supply circuits to the amplifier.
2. Test the sensitivity and mute circuits for an open or short to ground condition.
3. No audio output from the radio. Replace the radio.
4. No audio output from the amplifier. Test for any AC voltage between one speaker output circuit at the amplifier with the appropriate speaker disconnected and the radio volume adjusted to an audible level. If no AC voltage is present at the amplifier, replace the amplifier.

ALL SPEAKERS INOPERATIVE WITH REMOTE CD PLAYER - U1A

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

1. No voltage or ground present at remote CD player. Test the battery and ground supply circuits to the remote CD player.
2. No control circuit present at the remote CD player. Test the remote CD player control circuit between the radio and the remote CD player for an open or short to ground condition.
3. No audio output from the remote CD player. Replace the remote CD player.

Audio input present at the radio from the remote CD player. Replace the radio.

ALL SPEAKERS ON ONE CHANNEL INOPERATIVE WITH REMOTE CD PLAYER - U1A

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

1. No channel output from the remote CD player. Replace the remote CD player.
2. No channel input at the radio. Test the channel circuit between the remote CD player and the radio for an open or short to ground.
3. Channel input present at the radio. Replace the radio.

ONE SPEAKER 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. Test the appropriate speaker output circuits for an open or short.
2. Defective speaker. Replace the inoperative speaker.

No output from the radio. Replace the radio.

ONE SPEAKER INOPERATIVE WITH REMOTE AMPLIFIER - UZ6

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. Test the appropriate speaker output circuits for an open or short.
2. Defective speaker. Replace the inoperative speaker.
3. Audio output from the radio to the remote amplifier open or shorted. Test the appropriate radio output circuits for an open or short.
4. No audio output from the amplifier. Test for any AC voltage between the speaker output circuit at the amplifier with the appropriate speaker disconnected and the radio volume adjusted to an audible level. If no AC voltage is present at the amplifier, replace the amplifier.
5. No audio output from the radio. Replace the radio.

SPEAKERS - REDUCED VOLUME

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 circuit high resistance. Test the appropriate speaker output circuits for high resistance.
2. Low level audio circuit open. Test the appropriate low level audio circuit for an open.
3. Defective speaker - Replace the appropriate speaker.
