Quoted from Aniraf:Secondly, I have a kicker that pops balls from the subway under the playfield and back into play. About 5% of the time, it will take 2-3 fires before it can push the ball up and out.
Check that the optos are clean. Check that the coil sleeve isn't worn or cracked. Check the plunger to see if it's the right one, and not worn on the part that hits the ball. And the ball is getting a good hit, not a glancing blow if things aren't lined up.
Quoted from Aniraf:One, occasionally the solenoid which pushes the balls from the trough will just bounce up and down slightly while playing the game. It makes a noise because it is moving a chambered ball, but otherwise it is not applying enough power to get it into the shooter lane.
I'd suspect a switch issue - or switch matrix issue. Go into switch test, bang on the playfield - adjust anything that registers from vibration. Then I'd check switches and wiring for intermittent shorts that could pulse the switch matrix briefly and cause the ball trough VUK to start to fire.
