Looks to be a interesting game (ipdb). EM's can be a real bugger, when sorting faults. With the schematics you will certainly work it out. Don't let it beat you 
Must say though than I love fault finding EM's 
I dont, in all honesty EMs give me a large dose of the shits sometimes trying to locate faults (i lack patience
) especially if schematics arent on hand.
The beauty of them though is that 90% of the time it ends up being an easy fix to get them running!! nearly always as simple as switch cleaning/adjustment.
I'm sure you'll sort out the problems with yours though.. it just takes time to weed out the niggling little problems.. i'm STILL doing that with my Zac Universe
