(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.

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.
