other to terminals 1 and 2, check that the bulbs flash.
HINT:
The turn signal lights should flash 60 to 120 times per minute.
If one of the front or rear turn signal lights has an open circuit,
the number of flashes will be more than 140 per minute.
If operation is not as specified, replace the flasher.

3. INSPECT INTERMITTENT WIPER OPERATION
(a) Turn the wiper switch to INT position.
(b) Variable Type:
Turn the intermittent time control switch to FAST position.
(c) Connect the positive (+) lead from the battery to terminal
4/9 and the negative (−) lead to terminal 1/9.
(d) Connect the positive (+) lead from the voltmeter to termi-
nal 8/9 and the negative (−) lead to terminal 1/9, check
that the meter needle indicates battery positive voltage.
(e) After connecting terminal 7/9 to terminal 4/9, connect to
terminal 1/9.
Then, check that the voltage rises from 0 volts to battery
positive voltage within the times, as shown in the table.

If operation is not as specified, replace the wiper and washer
switch.
4. Low Speed:
INSPECT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 3 and
the negative (−) lead from the battery to the motor body, check
that the motor operates at low speed.
If operation is not as specified, replace the motor.
5. High Speed:
INSPECT WIPER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (−) lead from the battery to the motor body, check
that the motor operates at high speed.
If operation is not as specified, replace the motor.
6. Stopping at Stop Position:
INSPECT WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor op-
eration anywhere except at the stop position by discon-
necting positive (+) lead from terminal 3.

(b) Connect terminals 3 and 5.
(c) Connect the positive (+) lead from the battery to terminal
6 and the negative (−) lead from the battery to the motor
body, check that the motor stops running at the stop posi-
tion after the motor operates again.
If operation is not as specified, replace the motor.
7. INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (−) lead to terminal 1, check that the motor oper-
ates.
NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
If operation is not as specified, replace the motor.

3. INSPECT TACHOMETER ON−VEHICLE
(a) Connect a tune−up test tachometer, and start the engine.
NOTICE:
Reversing the connection of the tachometer will damage
the transistors and diodes inside. When removing or instal-
ling the tachometer, be careful not to drop or subject it to
heavy shocks.
(b) Compare the tester and tachometer indications.

If error is excessive, replace the tachometer.
4. INSPECT VOLT GAUGE SYSTEM
Measure the resistance between terminals A and B.
Resistance: Approx. 347 Ω
If resistance value is not as specified, replace the gauge.
5. INSPECT FUEL RECEIVER GAUGE OPERATION
(a) Disconnect the connector from the sender gauge.
(b) Turn the ignition switch ON, check that the receiver gauge
needle indicates EMPTY.
(c) Connect terminals 1 and 3 on the wire harness side con-
nector through a 3.4 watts test bulb.
(d) Turn the ignition switch ON, check that the bulb lights up
and the receiver gauge needle moves towards the full
side.
HINT:
Because of the silicon oil in the gauge, it will take a short time
for needle to stabilize.
If operation is not as specified, inspect the receiver gauge resis-
tance.
