Same here, only SOME of my lights never lit up until I wired the switches back up. If the test button doesnt work either, I would say your board is blown or the little wiring harness itself is shot. I am leaning toward the board going bad though.There is a test button and when you push that nothing happens either. As I said earlier, it is not an A priority as it runs and the snow season is upon us. I was just curious to see if anyone else had a quick fix for it. Other than the lights, it runs perfectly and is very dependable.
