I cut my landscape-lighting wire. Can I fix it?

Dear Edger,

You can fix this. A cut low-voltage landscape-lighting wire is frustrating, but it usually does not mean you need to replace the whole cable run.

Start by switching off the transformer. Then uncover enough undamaged cable on both sides of the cut to make a clean repair. For a permanent outdoor fix, use a waterproof connector made for low-voltage landscape wire. Electrical tape can look like a solution in the moment, but it will not keep moisture out for long once it is buried.

After the connector is in place, restore power and check the fixtures beyond the repair. If both lights come back at normal brightness, you are probably done. If the far end of the run still looks weak, do not assume you failed the repair. It may be pointing to another loose connection, a longer-than-expected run, or voltage drop that was already waiting to be noticed.

Take your time, make one clean splice, and test before you bury the wire again. This is exactly the kind of repair a determined homeowner can handle well. You are not starting over; you are learning how your system works.
