Over the time i heard alot of complains about the auto-plunger, where the ball wont make it up the heli ramp. I bought a shooter lane protector and after installing it the problem got worse for me, so i decided to examine the issue.
Short answer, if the ball doesn't touch both edges of the autoplunger metal piece, this is not good, and even increasing the autoplunge-power won't help, since the power can not connect. I removed the apron and was easily able to bend the metal piece housing as a whole with a pliers. I did this, because bending just one of the vertical brackets wouldn't solve the problem!
I increased my autoplunger power up to 200 (you find this in the game specific settings NO 300+...)
For those who want to use a shooter lane protector, make sure you install it with a ball in the shooter lane, and check if the ball touches both sides of the autoplunger. Moving the protector a tiny bit from left to right can cause a unconnected ball... use a piece of mylar to fix the protector in the right position.
Maybe this helps.
