Check Filament

NIS001CG

1.

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

2.

Attach probe circuit tester (in Volt range) to middle portion of
each filament.

3.

If a filament is burned out, circuit tester registers 0 or battery
voltage.

4.

To locate burned out point, move probe to left and right along fil-
ament. Test needle will swing abruptly when probe passes the
point.

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 (0.20 in)] of the break.

4.

After repair has been completed, check repaired wire for conti-
nuity. 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 minimum dis-
tance 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.

3.

As shown in the figure insert a small slotted screwdriver into the
recess between mirror base (mirror holder) and mirror holder
bracket and push up two pawls to remove mirror holder lower
half side. 

NOTE:
When pushing up pawls do not attempt to use one recess only,
be sure to push up with both recesses.
Insert screwdriver into recesses, and push up while rotating
(twist) to make work easier.

4.

Remove two terminals of mirror heater attachment.

5.

Lightly lift up lower side of mirror surface from mirror surface, and detach two pawls of upper side as if
