    2. Intermittent Operation Check
      1. Connect the voltmeter (+) terminal to the terminal 7 (+1) of the connector, the voltmeter (-) terminal to the terminal 2 (EW) of the connector.
      2. Connect the battery (+) to the terminal 7 (+B) of the connector, the battery (-) to the terminal 2 (EW) and the terminal 6 (+S) of the connector.
      3. Turn the wiper switch into the INT position.
      4. Connect the battery (+) to the terminal 16 (+S) of the connector for 5 seconds.
      5. Connect the battery (-) to the terminal 16 (+S) of the connector. Operate the intermittent wiper relay and check voltage between the terminal 7 (+1) and the terminal 2 (EW).
