Filament Check
1. Attach probe circuit tester (in volt range) to middle portion of
each filament.
lWhen measuring voltage, wrap tin foil around the top of
the negative probe. Then press the foil against the wire
with your finger.
2. If a filament is burned out, circuit tester registers 0 or 12 volts.

Filament Repair
REPAIR EQUIPMENT
1. Conductive silver composition (Dupont No. 4817 or equiva-
lent)
2. Ruler 30 cm (11.8 in) long
3. Drawing pen
4. Heat gun
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 over-
lap existing heat wire on both sides [preferably 5 mm (0.20
in)] of the break.
4. After repair has been completed, check repaired wire for
continuity. This check should be conducted 10 minutes after
silver composition is deposited.
Do not touch repaired area while test is being conducted.
5. Apply a constant stream of hot air directly to the repaired
area for approximately 20 minutes with a heat gun. A mini-
mum 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.
