Repair Log - Lighting - Centipede Marquee Light

Light Doesn't work right...
The Marquee light on my Centipede wasn't working correctly. The light was dark in the middle of the light and bright on the two ends.
The Light Fixture
The Marquee light fixture is pretty simple and is made up of only a few parts. The Sockets, Starter, Ballast and the Fluorescent Tube. You can read up more on how Fluorescent lights work here.

Since the light was lighting up, I could rule out a bad Tube (sort of).

The first thing I did was I replaced the Tube to make sure it wasn't that. Since it was lighting up, I just swapped them. If the light had not been on, I would have checked the Ballast first.

I put the new tube in and got the same results. I can now eliminate the Tube as the source of the problem. Since the tube was good, I went ahead and checked the Ballast using my Multi-Meter. It checked out good.

Fixed!
Since that was good, I dug out my last Starter (FS-2) and replaced it. Bingo! Light works great now.

We get light evenly across the marquee like it should be.
