Intermittent Circuit
- Connect negative lead of voltmeter to pin 2. Connect positive lead to pin 12. Turn ignition "OFF" and set wiper switch to "OFF". Battery voltage should be present. Turn wiper switch to "INT". No voltage should be read. If readings are incorrect, check harness and wiper switch.
- Connect negative lead of voltmeter to pin 15 and positive lead to pin 1. Turn ignition to "ACC" and wiper switch to "INT". Voltage should jump from 0-12 volts and back every couple seconds. If so, check wiper relay and wiring for problems. If amplifier does not operate as described, replace it.
- Connect negative lead of voltmeter to pin 2 and positive lead to pin 16. Turn ignition to "ACC" and wiper switch "ON". Rotate delay adjustment knob at end of wiper lever. Voltage should vary from 0 (short delay) to 8 volts (long delay). If wiper delay cannot be adjusted, but voltage is as described, replace amplifier. If voltage readings are incorrect, check harness and wiper switch.
