Inspection
- When measuring voltage, wrap tin foil around the top of the negative
probe. Then press the foil against the wire with your finger.

each filament.

- If a filament is burned out, circuit tester registers 0 or battery
voltage.
- To locate burned out point, move probe to left and right along filament.
Test needle will swing abruptly when probe passes the
point.

Repair
Repair equipment
- Conductive silver composition (dupont no. 4817 Or equivalent)
- Ruler 30 cm (11.8 In) long

Repairing procedure
- Wipe broken heat wire and its surrounding area clean with a
cloth dampened in alcohol.
- Apply a small amount of conductive silver composition to tip of
drawing pen.
Note:
Shake silver composition container before use.
- 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 (0.20 in)] of the break.

- After repair has been completed, check repaired wire for continuity.
This check should be conducted 10 minutes after silver
composition is deposited.
Caution:
Do not touch repaired area while test is being conducted.

- 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.
Note:
If a heat gun is not available, let the repaired area dry for 24
hours.
