OK here is the story. Last week my Ice cape 430 ballast shut down, I check the wiring its ok, the fuse(try 3 different ones to make sure). It lights up sometimes and stay on till they go are scheduled to go off, when I go to turn them on the next day they wont go on. I've tried different plugs. I've had it for well over 15 years with no problems now its giving me problems. IS IT DEAD?
