Hi, I have 2/ 250 Watt Metal Halide pendants on my tank. Everything has been working fine until yesterday Morning. When the lights come on, Only one of them lit up.I thought it was a bulb issue at first, so I changed out the bulb and still nothing. I then switched the ballasts from one side to the other and the ballast is working fine also. So, all that is left is the light fixture /Pendant unit itself. I have never had it apart before. Is there a starter unit or something in there that can go bad? Or maybe just the wiring come loose on the inside? Any Suggestions on What to look for inside this Pendant that would cause it not to light the bulb? Thanks!!!!!:sad:
