    Hi,

    I bought an outdoor lamp with light/movement sensor (Philips Creek 153883016). This lamp is designed to be off during daytime, and during nighttime it only switches on when movement it detected. However, I want do disable the movement sensor so the lamp switches on at night even if there's no movement.

    I checked the lamp's circuit board (https://www.dropbox.com/s/6kr06kbm5hfm07f/2014-08-10 16.20.03.jpg) and found a PID D204B, and I wondered if I could bridge it so it would always send a 'movement detected' signal, so the lamp would only be switched by the light sensor.

    I tried bridging the Drain and Source of the PID, but if I do that the lamp is always on, whether it is light or dark. I didn't blow the circuit or the PID, because when I remove the bridge between Drain and Source, the lamp works again as designed.

    The heart of the circuit is a LM324.

    Any ideas appreciated.

    You need to trace out a schematic for the board for others to comment.

    Here's the schematic, both in pdf and the original in Visio.

    Hope it makes sense, as I may have overlooked some connections on the small board.

    Thanks for helping out.
