Title: Marquee Light - Something so simple but so much grief.... Post by: jasonsmith on April 07, 2014, 09:33:29 pm Help me out here guys, I'm losing my mind. My Centipede marquee light was out so no biggie I thought, I'm going to change out the tube and starter like I normally do; that didn't work. Then I changed out the ballast, yes I'm throwing parts at it but I figured it's the only part left so WTH. Still no worky. Measured the voltage and I'm getting 121 across the white and black. Green is grounding to the ballast chassis and to the tube housing.
When on I get 121 across the upper poles of the lights, left and right side. I did a continuity check from the starter tabs to the tube pin tabs and they're both complete. I checked the tube tabs to the end of leads and they also are intact. Something is simply wrong that I'm missing. Help me out if you can.

Post by: lojack on April 08, 2014, 07:04:04 am well you can get a new bulb or just a new light kit. cheap bulbs from a no name brand are cheap for a reason. I have a friend that works at a lighting shop. they test the bulbs for you so you can see that it works. also on a side note, every box store has the black lights labelled wrong. 99% of them are black light blue (the blue tube). a true black light has a white tube.
best of luck on the light. |
