Sorry, forgot to update 
Couldn't find a midget, so I gave the switches a bit of a tickle and thus far seem ok. Sometimes I think the arm (don't know proper name) which kicks ball out doesn't work, as the ball doesn't appear in the lane when it should (ie maybe second time around).....
I will check the coil / diode on that but otherwise she is playing great!
this will be unrelated, the software can account for this and attempt until successful...it does rely on an operating shooterlane but of course doesnt need it to execute the transfer...as layer then sees ball in lane, proceeds to play anyway...are you getting the test fault knocker on startup?
