SOLAR RADIATION SENSOR INSPECTION
1. Using a tester, connect the positive (+) lead to solar radiation sensor terminal A, the negative (-) lead to
terminal B or C, then measure the resistance.
If the resistance is not normal, replace the solar radiation sensor.
Resistance
except infinity ohms
2. Block the light to the solar radiation sensor, connect the positive (+) lead of a tester to solar radiation
sensor terminal B or C and negative (-) lead to terminal A, then measure the resistance.
If the resistance is not normal, replace the solar radiation sensor.
Resistance
infinity ohms (no continuity)
3. Expose the solar radiation sensor to natural sunlight.
4. Using a tester, connect the positive (+) lead to solar radiation sensor terminal B or C, the negative (-) lead
