Default BIG Problems with my Tubes

Am back after some long time. I tried to experiment with my tubes in parallel or series as attached but was able to keep only 1 tube on. In the attached wiring its always tube 2 which gets on. From time to time 1 can get tube 1 but for only a few seconds but then tube 2 switches on and tube 1 is off. Could it be the ballast or something else?
If i connect only one tube it works fine but for two only 1 is on.

Thanks for the help

Sorry my UV box is at my other house. I don't have the drawings now as I made it over 10 years ago. I just copied the smaller unit sold by RS Components. I think I only have 1 starter and the tubes are wired in parallel.

Thanks again richie boy but the thing that strikes me is how it is behaving so strangely as only 1 tube is on. By the way these tubes come from an insect killer they sell at Game store here. I've lighted one of the units but its really light. I wonder if these actually use a ballast inside????? Its not worthwhile buying one to dismantle it. In case i can i'll try another ballast just to check. At worst the only choice is 4 starters, 4 ballast
