b. W/O Intermittent time adjust:
Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (-) terminal to terminal 5 (EW) of the connector.
2. Connect the battery (+) to terminal 8 (+B) of the connector, the battery (-) to terminal 5 (EW) and 6 (+S) of the connector.
3. Turn the wiper switch to the INT position.
4. Connect the battery (+) to terminal 6 (+5) of the connector for 5 seconds.
5. Connect the battery (-) to terminal 6 (+5) of the connector. Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5(EW).
c. w/ Intermittent time adjust:
Intermittent Operation Check
1. Connect the voltmeter (+) terminal to terminal 7 (+1) of the connector, the voltmeter (-) terminal to terminal 5 (EW) of the connector.
2. Connect the battery (+) to terminal 8 (+B) of the connector, the battery (-) to terminal 5 (EW) and 6 (+S) of the connector.
3. Turn the wiper switch to the INT position.
4. Connect the battery (+) to terminal 6 (+S) of the connector for 5 seconds.
5. Connect the battery (-) to terminal 6 (+S) of the connector. Operate the intermittent wiper relay and check voltage between terminal 7 (+1) and terminal 5(EW).
d. Operation Check (Washer switch)
1. Turn the wiper switch to the OFF position.
2. Connect the battery (+) to terminal 8 (+B) of the connector, the battery (-) to terminal 6 (+S) and 5 (EW) of the connecter.

2. WINDSHIELD WIPER MOTOR ASSY
a. LO Operation Check
1. Connect the battery (+) to terminal 1 (+1) of the connector, the battery (-) to terminal 5 (E) of the connector, and check that the motor operates at low speed (LO).
b. HI Operation Check
1. Connect the battery (+) to terminal 4 (+2) of the connector, the battery (-) to terminal 5 (E) of the connector, and check that the motor operates at high speed (HI).
c. Automatic Stop Operation Check
1. Connect the battery (+) to terminal 1 (+1) of the connector, the battery (-) to terminal 5 (E) of the connector. With the motor being rotated at low speed (LO), disconnect terminal 1 (+1) to stop the wiper motor operation at any position except the automatic stop position.
2. Connect terminal 1 (+1) and 3 (S), and the battery (+) to terminal 2 (B) to restart the motor operation at low speed.
