Does anyone know when the 3 lights in the exhaust pipe are turned on?
They work in testmode but I never see them on during gameplay.

@ MiamiRedSkin: you can buy one here

@ yurijos : - you can make a protector yourself from some leftover siderail or a piece of ss sheetmetal ( approx. 1mm thick)
- I had some problems with the kick out myself a few weeks ago, it all came down to proper alignment, had to try several times before it was ok again but didn't need a rebuild.

I tried various angles, just twisting and bending the bracket. Simple trial & error, no science
It is a weird angle, the ball has to go to the side while it is pushed down by the other balls.
I had the problem one more time after the last post so maybe I will need to rebuild it afterall.

@ yuriijos : experimenting at the moment, if I find a good solution i'll post it. The lockbar can be adjusted with the (brass) screws on the lockbar receiver.

@ yuriijos: after testing several stronger coils and positions, I ended up with the original coil but moved the bracket a few mm to the right (away from the switch). Mine was close to the switch , just touching it. Now the balls come out smootly.
