Solar Sensor: Testing and Inspection

Sunlight Sensor Test




Turn the ignition switch ON (II). Measure the voltage between the terminals with the (+) probe on the No.1 terminal and the (-) probe on the No.2 terminal with the 2P connector connected. The voltage readings will not change under the light of a flashlight or a fluorescent lamp. Voltage should be:
- 3.6 - 3.7 V or more with the sensor out of direct sunlight.
- 3.6 - 3.5 V or less with the sensor in direct sunlight.
