Solar Sensor: Testing and Inspection
INSPECTION
INSPECT AUTOMATIC LIGHT CONTROL SENSOR (SOLAR SENSOR)
Connect the battery's positive (+) lead to terminal 6 and the negative (-) lead to terminal 3, then measure the voltage according to the value(s) in the table
given.
NOTE: The connection procedure for using a digital tester such as a TOYOTA electrical tester is shown.
HINT:
-
As the inspection light is moved away from the sensor, the voltage decreases.
-
Use an incandescent light for inspection. Bring it within 30 cm (11.8 in.) of the solar sensor.
If the result is not as specified, replace the solar sensor.
