Testing Troubleshooting

Before you finish the installation, you should do the following tests to make sure the wiring is correct and everything is operating properly.

Reconnect Battery

When wiring is complete, reconnect the battery negative terminal.

Test power wiring

1.Turn on the head unit but do not turn up the volume. The amplifier power light should come on. If not, check the remote and +12 volt wires. Also check the ground connection.

2.Turn up the head units volume slightly. All speakers should operate. if not, check wiring connections at amplifier and speakers.

Test speaker connections

Make sure the speakers are connected right. Use the balance control on the head unit to make sure right channel is on right speaker etc. If speakers don´t play at all, one or both speaker wires may be disconnected.

If problems occour during the installation, or later, this guide might help you to find out whats´s wrong.

THE AMPLIFIER IS DEAD:

1.Check power lead, ground and remote connections at the amplifier using a multi meter.

2.Check the battery terminal connections.

3.Check the power lead fuse or circuit breaker. If fuse damage continues, inspect the power lead for short circuits.

4.Check the amplifier protection fuses. Are these broken change to new ones with the same value. If short circuiting continues, contact your local DLS dealer. A fault may exist in the amplifier.

5.To start the amplifier requires a remote voltage of 9-15 volt. Check the voltage with a multimeter.

AMPLIFIER PROTECTION FUSE BLOWS AT LOW VOLUME :

1.One or more speaker cables are shorted. Make an insulation test with a multi meter. The cables must not have a connection to earth.

THE AMPLIFIER TURNS OFF AFTER 10 - 30 MINU- TES.

The amplifier is overheating due to inadequate ventila- tion. Check mounting position is free from obstruction.

Do this:

1.Move the amplifier to a place with better ventil- ation.

2.Install one or two fans to cool down the heat-

sink.

3.Overheating can also be caused by an impedance load below the level permitted.

NO OUTPUT FROM ONE OR MORE SPEAKERS:

Check the following:

1.Balance control position.

2.Fader control position.

3.Speaker cable connections to both amplifier and drivers.

4.Signal lead plugs and cables.

5.Change left and right signal lead plugs in the amplifier to see if the problem moves to a diffe- rent speaker, the lead has a fault.

If the problem remains, the speaker or amplifier are at fault.
