      2. Check the intermittent operation.


        1. Connect the positive (+) lead of a voltmeter to terminal A-3 (+1) and the negative (-) lead to terminal B-2 (EW).

        2. Connect the battery positive (+) lead of the battery to terminal A-2 (+B) and the negative (-) lead to terminal B-2 (EW) and A-1 (+S).

        3. Turn the wiper switch to the INT position.

        4. Connect the positive (+) lead of the battery to terminal A-1 (+S) for 5 seconds.

        5. Connect the negative (-) lead of the battery to terminal A-1 (+S). Operate the intermittent wiper relay and check the voltage between terminals A-3 (+1) and B-2 (EW).

          OK
          The voltage changes as shown in the illustration.
