POWER SUPPLY ROUTING
This diagram is helpful in identifying specific prob-
lems
in the power supply portion of the electrical
circuits. For example, let's say
a vehicle has an in-
operative
rear window defogger A quick check
proves that meter and
gauges in the vehicle are
operative The power supply diagram shows that
there cannot be
a problem between the battery,
ignition relay, ignition switch or fuse since the
power supply circuit for the
rear window defogger
Example
BRANCH M/T model
AlT model

ABBREVIATIONS
is common with the meter and gauges. Therefore,
the cause of this specific problem must
lie past the
fuse, such
as in the wiring, rear window defogger,
or ground.
WIRING DIAGRAM
This diagram identifies types and number of con-
nectors, electrical
terminal positions in the connec-
tor, color coding of wires, and connector codes
Refer to the following example

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

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.
