Quoted from SwissMTNAlien:1. The left trough bumper keeps triggering and going off without a pinball even near it... constantly throughout the game. If I hit the left flipper I can make that bumper go off sometimes as well. This was not an issue until now. Any ideas or should I open up a ticket?
The left slingshot kicker ? If so -
Turn the game off. Remove the plastic over the sling shot kicker and leaf blade switches. Pull on the rubber ring around the posts, so you have equal pressure on all sides, not tight on the kicker/leaf blade switch side. The leaf blade switches - front long one should be resting on the rubber ring, not pushing it or away from it. Shorter rear one should be close enough so the slightest ball hit triggers it, yet vibration doesn't. There are two leaf blade switches, one each side of the kicker. At least one needs a little adjusting. When bending forward or backward, get as close to the fiberboard spacers as you can.
Quoted from SwissMTNAlien:2. The ball often doesn't sit properly on the plunger so it often comes back down the shooting lane. Looks like the plunger strength is not the issue, but rather how the pinball sits on the plunger after being ejected from the trough.
If it's hanging up on the switch in front of the plunger, adjust it so it doesn't effect the plunger but still works when a ball rolls on it ? Or the plunger isn't hitting the center of the ball ? If loosen the screws holding the bracket/coil/plunger and aim the plunger better and retighten the screws.
