So, I managed to get the fixture working again. Delphinus suggested that I man the 'eff up and just crack it open to fix it. That's what I did and found some salt creep and a loose wire. A bit of rewiring and clean up seemed to fix it. HOWEVER, now one of the ballasts seems to have gone. I suspect due to me unplugging and plugging it in constantly. This particular ballast was always flaking (often cut out if it got too warm) so I'm not surprised actually. The ballast is easier to replace, except that now I have to replace it.. Not sure if I'll even find another Galaxy Ballast so I may have to find another brand. I don't really want a magnetic ballast (they're way too noisy), even though they are more reliable..
