5. w/ Heater:
INSPECT MIRROR DEFOGGER
(a) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to terminal 6.
(b) Check that the mirror becomes warm.
HINT:
It takes short time for the mirror to become warm.
6. INSPECT DEFOGGER WIRE
NOTICE:

When cleaning the glass, use a soft, dry cloth, and
wipe the glass in the direction of the wire. Take care
not to damage the wires.

Do not use detergents or glass cleaners with abrasive
ingredients.

When measuring voltage, wind a piece of tin foil
around the top of the negative probe and press the foil
against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5VOkay (No break in wire)
Approx.10V or 0VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative (±) lead with the foil strip
against the heat wire at the positive (+) terminal end and
slide it toward the negative (±) terminal end.
(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.

3. INSPECT MIRROR MOTOR
(a) TMMK made (w/o Heater):
Connect the positive (+) lead from the battery to terminal
1 and negative (±) lead to terminal 2, check that the mirror
turns to left side.
(b) TMC made (w/o Heater):
Connect the positive (+) lead from the battery to terminal
3 and negative (±) lead to terminal 2, check that the mirror
turns to left side.
(c) TMMK made (w/ Heater):
Connect the positive (+) lead from the battery to terminal
3 and negative (±) lead to terminal 2, check that the mirror
turns to left side.

If the voltmeter reading is less than standard voltage, check the
voltage regulator and generator as follows:

With terminal F grounded, start the engine and
check the voltmeter reading of terminal B.

If the voltmeter reading is more than standard volt-
age, replace the voltage regulator.

If the voltmeter reading is less than standard volt-
age, check the generator.
9. INSPECT CHARGING CIRCUIT WITH LOAD
(a) With the engine running at 2,000 rpm, turn on the high
beam headlights and place the heater blower switch at
ºHIº.
(b) Check the reading on the ammeter.
Standard amperage: 30 A or more
If the ammeter reading is less than the standard amperage, re-
pair the generator.
HINT:
If the battery is fully charged, the indication will sometimes be
less than standard amperage.
