[Lawn Lad]

We have an existing customer that we do the maintenance work on, someone did the installation prior to our taking over the property.

The problem is a run of path lights that went out, so we replaced the wire which was corroded at each connection. The lights have gone out again. If we replaced the wire, and the whole run is going out, I'm inclined to think there may be an issue with the transformer. What happens to transformers over time and how do you know when they go bad (other than completely not working). Because this problem has been intermittent, we're scratching our noodles a bit.

Thanks for any suggestions.
