Did you buy a supported unit? Then don't be surprised that someone has already tampered with the wiring and broken the wiring circuit. If I were you, I'd replace all the wires again. Otherwise, your spotlight may never work. Of course, you may not be able to see where the circuit was broken, but that's probably how it is. Buy another spotlight if replacing the wires and soldering doesn't help you. I buy mine from vont.com because they work well enough and have a good range. I think their range is high enough for both stage and outdoor use. Do you want to build equipment for a concert hall or something like that, or do you want to put your spotlight in your yard to turn on in emergencies?
