Testing
Before you finish the installation, you should do the
following tests to make sure the wiring is correct and
everything is operating properly.
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 multi meter.
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 venti-
lation. 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.
Troubleshooting
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.
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.
