Yeah, agreed on the troubleshooting 67Dart. Just thought that for a non electronic guy replacing the two obvious parts might be a cheap first shot. Everything else gets a lot harder.
...........And I'd agree that this is a variable that can be subjective. Frankly, if the supply voltage TO the ballast is OK, and the ballast is not cutting out/ intermittent etc, then it itself is likely OK. The other issue of course, with replacement...............is the Chineseoationized "quality" of today's parts.
