Intermittent Wiper Relay Circuit
1) Disconnect negative cable at battery.
2) Disconnect combination switch lead wire coupler.
3) Turn the front wiper switch to INT position.
4) Turn the intermittent time control switch to FAST position.
5) Connect battery positive terminal to terminal "B3" and battery
negative terminal to terminal "E".
6) Connect voltmeter positive lead to terminal "+1" and negative
lead to terminal "E".
Check that the voltmeter indicates the battery voltage (10 –
14 V).

7) Connect terminal "As" and terminal "B3" by a jumper wire. Then
move jumper wire end connected to terminal "B3" to terminal "E".
Observe the voltmeter voltage drops to 0 V right after connecting
the jumper wire from terminal "B3" to "E". Then the voltage rises
to battery voltage (10 – 14 V) within the time shown in the table
below.
