Try tearing the whole thing down. I had a problem in single player before (possibly with an older version though), where some ordinary luminators ate a whole batbox like it was nothing. And no matter what I did they continued gobbling power. Even when I tore down the cables the power connection somehow magically remained. So I pulled all equipment in a 10 block radius down and restarted from scratch, adding the luminators one by one, then it worked.
I don't know if this is a similar problem, or if you have already tried it, but that's all I got.
