Been working on this damn thing since last fall. Stays on all the time. Even changed photo cells. Anyone see what is wired wrong?

Thanks, James

The hot wire is feeding the black wire on the ballast. The blue from the ballast and the blue from the ignitor are feeding the photo cell line wire. The red from the ballast and the ignitor are together. The red photo cell wire is the hot to the light. All the whites are together. This is kicking my stupid ass. :confused:

Thanks,James

Why is the photo eye not on the main power wire? You don't switch the lead to the socket for turning it off and on.

The photoeye's I've worked with use black for the constant power, and red is the switched power.

Try this:
Hot to the photo-eye black.
Red to ballast black.
All whites together.

Leave the ballast/ignitor/socket arangement as it was before you messed with it. (as per wiring diagram) :D

The hot wire is feeding the black wire on the ballast.

Not sure if I am reading this correctly. The hot is going to the ballast first? Then that is the problem. Hot should go through the photocell first and then to the ballast. Just think of the photocell as a switch. Run the power through it and then to the light.

And if that doesn't work you have a very good chance of a bad photo-cell. Clean the lens ( get bird poop off) and test the photo-cell for continuity.

Thanks

Glad I could help. Reading through your description, it sounded like you had the power going to the light first and then the switch -- thereby making the switch totally ineffective.

Good luck on your recovery. Hope that all went well with that.
