It's pretty easy to follow the ballast leads to see which lamps they do. You might want to get a known good pair of lamps (new ones, perhaps) and try them and see what you're up against. You may have one bad ballast, or maybe even two. You need to put in a good set of lamps first to see if your lamps are bad or if it's your ballast. If you can't get a good set of lamps to lamp up in either the inside or the outside pair of sockets, then you have two bad ballasts. Evaluate the condition of the rest of the fixture for possible replacement as a unit, as the cost of two new ballasts can sometimes exceed the cost of a new fixture in some of the more plain styles.
Thank you, I should of said what you stated but...I am not too good with wiring.
I bought a new set of bulbs and tried them in the outside and inside. Still nothing.
The light had been getting slower and slower to turn on and then it didn't come on at all. Is that common for both ballast to go?
Anyway, as far as a starter I don't think it has a external one and there is only the two ballast and some wires.
