Hello .. Rich here .. lets see if I can help you figure this out
is this the only light on this circuit or switch ?
do you have a two wire voltage tester ?
do you remember how the wires were connected to the old fixture ?
Rich, The wires I'm sure were incorrectly connected to the previous lighting unit. I did it a few years ago and bulbs kept blowing out every three months.
well there are two choices for normal wiring methods here one, there is a switch wired into this box two, there is another light beyond this one that is controlled the same as this one . since this one is on a photo eye , it may be another light also controlled by a photo eye
if therte is a switch wired into this box then it makes a difference in the wiring
On the wall swith plate inside the house I have two switches. One controls the lights on the inside of that room and the other controls just this outside lighting unit.
let me take the obvious first .. green wires ,, together , pigtailed to the box if it mis a metal box .. and pigtailed to a screw on the fixture or fixture mounting bar IF provided otherwise stuff them
No green wires. Just the green ground screw inside the receptacle.
coulod be barte ground wires ..
OK .. if there is no other light involved then I am going to say taht two of the wires are hot , black and white ,.. and the other two are going to the switch you could confirm this by taking a look inside the switch box and seeing if the switch for this light has a black and white on it .. or two blacks
sorry the ground wires can be green or bare
let me know about the wires on the switch and I can finish telling you how to connect the light
The four wires coming from the wall to the outside light are balck and white. Two black & two white. The CS902 lighting unit has a red photocell wire that the instructions say to connect to the black lighting unit wires and doesn't mention connecting them to the black wall wires. The instructions do say to connect the two lighting unit white wires to the wall white wires.
yes but if there is a switch leg in the lighting box then one pair of those wires from the house need to be connected differently .. were any of the wires connected together but not connected to the old light fixture ??
Correction: The instructions do say to connect to the black lighting unit wires to the black wall wire. But then I still have one black wall wire available. i don't know what to do with that and what about a ground wire?
the ground wire may not connect .. if there is no ground wire from the house or screw it tio the metal box
So I may not have to grond it?
Also what do I do with the additional black wall wire?
that depends if there are a white and black on the switch .. or two blacks on the switch
Do you mean behind the switch plate in the house?
yes .. you may be able to see without taking the switch out ., oh have you turned off the breaker for this circuit b??
Can you wait 5 minutes while i take the inside switch plate off and check.
P.S. I did turn the circuit breaker off when I was trying to install the outdoor light. Back in a few minutes.
Both the 2 black and 2 white wires are connected to the switch in side the house for the outdoor light.
that is more strange
Should I take the one lampholder black wire and connect it to both the wall black wires and not be concerned about a ground wire?
OK .. connect the house whites together with the fixture whites .. connect the house blacks together to the black fixture wire .. connect the red wire to the other lamp wires ./. do not worry about the ground
OK. Can't do it now because it's too dark out. I'll try that tomorrow. Thanks. Bob
Ok .. you can get back to me here tomorrow if vyou need to
Thnaks. Good night.
