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.
