Intermittent Circuit
- If power supply circuit is okay, turn wiper switch to "INT" position. Turn ignition switch to "ACC". Connect voltmeter to terminals No. 2 and 15. Voltmeter needle should deflect every 3-12 seconds.
- Turn ignition switch to "OFF" position and leave wiper switch in "INT" position. Check continuity between terminals No. 2 and No. 12. Ohmmeter should show zero ohms.
