I Have 3 Halogen Outdoor Recessed Lights Hooked To A Motion Sensor. The Sensor Keeps Getting Fried. Why? These are switched controled. All neutrals hooked together, hot to the sensor and then to lights.

How many watts per bulb? Any info on bulb & sensor would help.Are the bulbs 12v with a transformer?

What is the voltage for the sensor?

[FIRE1953]

The bulbs are 60w, the sensor is rated to 300w. There is no transformer in the system. I have been told it has something to do with the way things are wired, which I believe is parallel. The sensor has 3 wires. common(white), hot(black) & sensor hot(red). I have all commons tied together, hot from switch to black on sensor and black to lights on senor hot (red)

It keeps getting fried? Do you replace it with a new one every time it is fried? It sounds like you have it wired correctly. All the whites (neutrals) spliced together. The hot from the switch (the normal wall type, that you can operate) on the wall, to the black wire on the sensor. And, the red wire from the sensor, to the black wires on each light.

Yes, I have replace the sensor. Does it make any difference that the wiring goes from senor red to black light one--wire to light 2 wire to light 3? Same with sensor white to neutral one--wire to light 2 wire to light 3? I was told this might be the issue, but for the life of me I can't figure out why?

It sounds like your wiring is correct. Typically on a sensor switch, the black wire is the power in, and the red wire is the "switch leg", the wire that feeds the lights from the sensor. Try testing the circuit that is feeding the sensor for the correct voltage, one lead on the black wire (that is feeding the sensor), and one lead on the neutral wire (that is feeding the sensor). Make sure that you have 110 volts to 120 volts AC. Any more than 130 volts may fry the sensor. The red wire on the sensor should be only connected to the black wires on the light fixtures that you want switched.

Neutrals.
Make sure the neutral (white wire) on the sensor is connected to the neutral (white wire) from the circuit that is feeding the sensor, and to the lights that the sensor is feeding. With 3 lights, there should be 5 neutrals spliced together.
