In a fixture with two inductive ballast's and the usual starter arrangement, if the wires are mixed so that one tubes "A" cathode is wired through the starter to the other tubes "B" cathode, then it creates a kind of flip-flop condition where the first tube to light stops the other lighting. If the starters were removable, then the removal of one would show a single electrode glowing on each tube during the starting attempts. another poster gave this pdf: http://www.advancetransformer.com/li...cket_Guide.pdf if you scroll down to page 26, "troubleshooting", they describe the exact problem me@my reported. the text makes clear that it is a common problem with unpredictable operating results, that range from almost normal (intermittent?) operation or one bulb operation, to not working, to premature lamp and ballast failures. some of the RCM'er have described these very symptoms, drives them crazy wondering what the hey is happening. this pdf is worth the download for anyone using flourescent shop lites. --Loren ps. followup-to set to sci.engr.lighting |
