Hi Dana, thanks for responding.
I don't have a schematic and the only identifier on the sensor in JH2003.
Every one of these lights purchased has this same problem according to my experience and the reviews.
The sensor isn't the same as the other units I have with vcc, out and ground, it has L+ L- B+ and B-.
The light as power going to it and it appears the negative lead from the batter is being switched to operate the light.
The positive from the battery goes to a B- on the far end of the light.
Big Clive has a video for the other pir sensors Big Clive .
These lights can be rewired to work, I bought two and both false triggered.
battery- (blk) from pir goes to - battery pack.
battery + (red) from pir to B- on light.
L+ (red) from pir to L+ on light.
L- (blue) from pir to -L on light.
