Filament Repair
REPAIR EQUIPMENT
1 Conductive silver composition
(Dupont No 4817 or equivalent)
2 Ruler, 30 cm (1 1 8 in) long
3 Drawingpen
4 Heatgun
5 Alcohol
6 Cloth
REPAIRING PROCEDURE
1 Wipe broken heat wire and its surrounding area
clean with
a cloth dampened in alcohol
2 Apply a small amount of conductive silver
composition to tip of drawing pen
Shake silver composition container before use.
3. Place ruler on glass along broken line. Deposit
conductive silver composition on break with
drawing pen Slightly overlap existing heat wire
on both sides [preferably 5 mm (020 in)] of
the break.

4 After repair has been completed, check re-
paired wire for continuity This check should
be conducted
10 minutes after silver composi-
tion
is deposited
Do not touch repaired area while test is being con-
ducted
r point

5 Apply a constant stream of hot air directly to
the repaired area for approximately
20 minutes
with
a heat gun A minimum distance of 3 cm
(1 2 in) should be kept between repaired area
and hot
air outlet If a heat gun is not available,
let the repaired area dry for 24 hours.

AUDIO AND POWER ANTENNA
Power Antenna Motor Check
1 Disconnect, at connector, harness between
power antenna unit and antenna timer.
2 Apply 12-volt battery voltage across @ and
@ to make Sure antenna rod extends and
retracts
3. Connect a voltmeter across terminal 0 and
ground terminal
of battery.
4 Check to determine if voltmeter varies between
0 and 12 volts (approx ) in relation to move-
ment
of antenna rod when 12-volt battery
voltage
IS applied across @ and @
If above test results are not satisfactory, re-
place antenna
motor.
