Solar Sensor: Testing and Inspection
AIR CONDITIONING: SOLAR SENSOR (for Automatic Air Conditioning System): INSPECTION
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:
NOTE: 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.
HINT: If the result is not as specified, replace the solar sensor.
