Common issues to troubleshoot:
- First things first, when you arrive on site you need to locate the transformer. Then with your volt meter make sure the outlet has a 110 volt reading. Good there?
- Determine if the site has a photo cell, this will be located on the side of the transformer. If the system has a photo cell, then you need to bypass it by covering the round photo eye with electrical tape. This should activate the lights and help to rule out any issue that the photo cell may be causing. It will also allow you to have power throughout the lighting system as you continue your checks.
- Then verify voltage output at transformer by touching your volt meter to ports 12, 13 and 14. Looking for a corresponding volt reading for each from your meter
- For fixtures that are not working you are going to remove that lights wire connectors and check the wires leading to the light from the transformer with your volt meter. Looking for that 12, 13 or 14v response
- If you have power just redo the connections, it is possible that something inside the wire nut got corroded
- If fixture still doesn’t work replace bulb if replaceable
- If still not working then it is a bad fixture. Remove the fixture and take it to your lead for replacement
- If there was no power to the wires go to previous working light and redo connection there
- If still not working wire is likely broken, you will need to replace the wire between the lights
- Once all lights are operational again remove electrical tape from photo eye on photo cell and secure cover on transformer
