Hello guys my machine has a problem with second face multiball. When both eyes are covered the balls are released and "blocked" by the plunger. The face turns and the plunger goes down once, letting only one ball to come down. The other gets stuck in the position pictured so the system doesn't know that it is there!

It is released only if you send another ball up or if you lose the ball and the pin starts the ball check..can you help me solve this problem? I've already checked the switch and they work well..are the ball supposed to go down both togheter or the plunger needs to go down 2 times?

Thanks for the help!!

Fourbyracer you got it! The switch is correctly pressed when a single ball is up there (voice activated). When two balls are up, the switch are both correctly pressed (in fact the eyes are activated). The problem comes when the first ball is released and the second goes down too much, remaining between the plunger and the front switch! My plunger can jiggle a little (is yours fixed in its position?) and maybe the ball keeps it pressed too much down. But it seems strange because, when a single ball is up, there isn't this kind of problem and the switch is correctly pressed.

Anyway the switches cannot be moved up or down (only a bit left and right) they are fixed to the ramp! Is the problem in the plunger movement?

Hope to be understandable thank you guys!

I've bended it a bit and hen cleaned the whole assembly putting on a new coil bushing and.. It seems to be solved for now! thank you!!

I have to understand why the bop bumpers aren't much sensitive, only a strong ball activate them..tomorrow I'll try cleaning them too!
