I'm building a Zombie-F'esque sign for my front yard and I've got the circuit built, but it won't even turn on. I'm using a FS-4 (30-40W) with a 25W bulb and I've verified all the wiring for continuity. If I short across the starter, the bulb lights up fine. But with the starter in the circuit, it won't do anything. Am I using too big of a starter? Any ideas? Thanks!
