HEATING / AIR CONDITIONING: SOLAR SENSOR: INSPECTION

1. INSPECT SOLAR SENSOR (AUTOMATIC LIGHT CONTROL SENSOR)

(a) Remove the solar sensor with the connector still connected.

(b) Apply battery voltage between terminals 6 (CLTB) and 3 (CLTE) of the A/C solar sensor.

(c) Measure the voltage according to the value(s) in the table below.

Standard Voltage:

If the result is not as specified, replace the 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 solar sensor.
