Jerry,

I am sure you already checked the connections at the breaker box itself.

On mine, there were several wires that were loose and could be tighten quite a bit more.
On the kitchen light...it would work & then it would not...then it would & then it would not....
turned out that it was making a connection sometimes & sometimes it wasn't.
Maybe DRV ran a separate line from the island to breaker box and the connections are loose at breaker box??

Good Luck
