TROUBLESHOOTING

SPECIFICATIONS

•PROBLEM:

BassLink II and 4sc Power LEDs are not lit. CAUSES and SOLUTIONS:

1.Poor or improper power connection. Check power, ground and remote connections. Check speaker level input for proper connections (see No Output).

2.Blown or improperly installed fuse. Check main battery fuse and replace if necessary.

Check fuse on BassLink II and 4sc.

•PROBLEM:

4sc Power LED not lit but BassLink II Power LED is.

CAUSES and SOLUTIONS:

1.Improper power connection between BassLink 4sc and BassLink II. Check Power Connector (see Installation, Figure 2).

2.Improper signal connection between BassLink 4sc and BassLink II. Check gray ribbon signal cable connection to the 4sc (see Installation, Figure 2).

3.Blown or improperly installed BassLink 4sc fuse. Check fuse and replace if necessary.

•PROBLEM:

BassLink 4sc Power LED lit but no sound from one or all speakers.

CAUSES and SOLUTIONS:

1.Improper input signal connections. Check all input connections on BassLink II and source unit.

2.Damaged speaker wire or improper speaker connections. Check speakers and wiring; change if necessary.

3.Improper signal connections between BassLink 4sc and BassLink II. Check gray ribbon signal cable connection to 4sc (see Installation, Figure 2).

•PROBLEM:

Music sounds distorted. CAUSES and SOLUTIONS:

1.Gain levels are set too high or head unit volume is too high. Reduce volume and/or Gain Levels.

2.Tone Controls on head unit misadjusted. Check controls and adjust as necessary.

•PROBLEM:

No output from BassLink 4sc and BassLink II.

CAUSES and SOLUTIONS:

Input connections are improperly wired. Verify all connections (see Figures 4 and 5).

•PROBLEM:

No output from BassLink II when head-unit fader control is set to front or rear (in a 4-channel connection).

CAUSE and SOLUTION:

Input connections are improperly wired. Verify all connections (see Connections, on page 3).

•PROBLEM:

BassLink II turns on before head unit is completely on and produces a “thump” sound.

CAUSE and SOLUTION:

For speaker-level connections, head unit is producing a false turn-on signal. On BassLink II’s side panel, slide AUTO TURN ON to OFF. It will be necessary to connect the Remote lead

to a switched ignition voltage source.

•PROBLEM:

BassLink II’s BassLink 4sc POWER LED remains on after head unit is turned off.

CAUSE and SOLUTION:

For speaker-level connections, this is normal operation when AUTO TURN ON is set to ON. BassLink II and BassLink 4sc will remain on for another 5 to 10 minutes after sensing that audio signals are not present before shutting down.
