Ambient Light Sensor: Description and Operation
PURPOSEThe Day/Night Sensor/Amplifier monitors ambient light in order to control the autolamp relays.
OPERATION
As light level decreases, the sensor resistance increases to a preset amount. This energizes the autolamp relays, which turn on the headlamps, the exterior lamps, and the instrument illumination lamps.
ADJUSTMENT FEATURE
The sensor can be adjusted by rotating a sensitivity screw toward the EARLIER or LATER markings on the sensor. The manufacturer's directions are printed on the unit.
