I have a Heath Zenith motion sensor. I had it attached to a lamp and it worked. I removed the lamp to paint leaving the motion sensor in place. When I replaced the lamp, the lamp/sensor combination does not work. The number on the sensor is 8118593TAP. Can tell me what may be wrong with the reinstallation and/or redirect me to an installation procedure to figure out what error was made in the connections. I do hear a clicking sound when I turn the power on.
