Solar Sensor: Testing and Inspection

AIR CONDITIONING: SOLAR SENSOR (for Automatic Air Conditioning System): INSPECTION

1. INSPECT SOLAR SENSOR





(a) Using an ohmmeter, connect the positive lead to terminal 2 and the negative lead to terminal 1, then measure the resistance between the terminals.

Standard resistance:





NOTICE:
The connection procedure for using a digital tester such as a TOYOTA electrical tester is shown above. When using an analog tester, connect the positive (+) lead to terminal 1 and the negative (-) lead to terminal 2 of the A/C solar sensor.

HINT
* As the inspection light is moved away from the sensor, the voltage increases.
* Use an incandescent lamp for inspection. Bring it within 30 cm (11.8 in.) of the A/C solar sensor.
If the result is not as specified, replace the solar sensor.
