Thanks Beaky.I suppose what Im thinking is ...should I be mucking around with circuit boards only having had pinball machines since may.Having read a few sites on boards they do warn that experience is esential and send your board to professionals.I am assuming coil diodes are ok as I have tried 3 different coils and all blow fuse.I have been using 500ma slow blow fuse as I am in Portland Vic and that is the lowest I can get around town(will get some on line)I also saw on one site that a new board is only $30 would this be a better way to go considering my inexperience at soldering and fault finding.On the plus side the cricket is on .Cheers Scott.
