at the etched voice-coils (thin silver
lines) and diaphragms (thin plastic
films). Look for punctures, broken lines,
or lines which are coming loose. If you
find any damage at all, call your
Infinity dealer for instructions. If you
find no damage, check to see if the
wires are properly connected. Tighten
and/or reconnect the wires if necessary,
and if the problem persists go on to...
Step 3: Remove the suspected tweeter
and put it in the place of one that
operates properly. If the suspected
tweeter does not play, it is defective.
If it plays, the problem may be in
the passive crossover; call your
Infinity dealer and describe the
problem.
If the top and bottom front tweeters
are apparently not working....
Step 1: Same as previous "step 1."
Step 2: Same as previous "step 2"
(except for the thru-bolts).
Step 3: Disconnect the lead wires
from one
of the tweeters,
and connect
or
"short" the two wires together. If the
other
tweeter plays,
then the
one which
you have disconnected
is defective;
call
your Infinity
dealer
for instructions.
If the second tweeter does not play,
reconnect the first tweeter, disconnect
the second, and repeat the procedure
just described. If neither tweeter plays
alone during these tests, both tweeters
may be defective. Remove the tweeters
and put them, one at a time, in the place
of one that operates properly. If the
tweeter does not play, it is defective.
If both tweeters play in this test, the
problem may be in the passive crossover;
call your Infinity dealer and describe
the problem.
If the top, second, and fourth
midrange drivers are apparently not
working...
Step 1: Without removing any of the .
midrange drivers, check all wiring
connections. Tighten and/or reconnect
them if necessary. If the midranges still
do not work, disconnect the lead wires
from the top midrange and connect or
"short" the two wires together. If the
second and fourth midranges play, the
top midrange is the one at fault. If
they
do not play,
reconnect
the oe
midrange and go on to...
Step 2: Disconnect the lead wires
from the second midrange driver and
connect or "short" the two wires
together. If the top and fourth mid-
range drivers play, the second midrange
is the one at fault. If they do not
play, reconnect the second midrange
and go on to...
Step 3: Disconnect the lead wires
from the fourth midrange driver and
connect or "short" the two wires
together. If the top and second mid-
range drivers play, the fourth midrange :
is the one at fault. If they do not
play, two or all three midranges, may
be defective. Remove the midranges and
put them, one at a time, in the place
of one that operates properly. If a
midrange does not play, it is defective.
If all the midranges play in this test,
'the problem may be in the passive
crossover; call your Infinity dealer
and describe the problem.
If the third midrange driver is
apparently not working...
Step 1: Check the EMIM fuse and
replace if necessary. using only the
jsame size and type fuse.
Step 2: Check all wiring connections,
and tighten and/or reconnect:them if *
necessary. If the midrange still does
not work, go on to...
Step 3: Remove the midrange and put
it in the place of one that operates
properly. If the midrange does not
play, it is defective. If the midrange
plays in this test, the problem may be
in the passive crossover; call your
Infinity dealer and describe the
problem.
If the fifth, sixth, and bottom
midrange drivers are apparently not
-working...
Step 1:. Without removing any of the
midrange drivers, check all wiring
connections. Tighten and/or reconnect
them if necessary. If the midranges still
do not work, disconnect the lead wires
from the fifth midrange and connect or
"short" the two wires together. If the
sixth and bottom midranges play, the
"fifth midrange is the one at fault. If
they do not play, reconnect the fifth
midrange and go on to..
Step 2: Disconnect the lead wires
from the sixth midrange driver and
