I have a couple of issues with my Xenon and would like some advice.
1st issue, sometimes when shooting the ball through the tube, it will exit without falling into the saucer - just go straight out of the gate. How do I fix this?
2nd issue, the middle pop bumper worked sporadically, when I looked under the playfield, the switch underneath had only 1 screw, which was extremely loose. I tightened that 1 screw, making sure the switch was in the correct position. The bumper worked great after that.
Today I was changing a light socket, and the one screw thing was bugging me, so while I had the playfield up, I installed a second screw to ensure the switch wouldn't come loose again.
I fired the game up in lamp test to make sure all the lamps worked, which they did. I started a game, and the middle bumper did not work. When the ball hit the wafer, it would score (I think) and make the Ahhh sound, but the solenoid would not fire. I went into solenoid test and the same thing - all solenoids would fire except for this bumper (09 in the display).
I removed the screw I installed and turned off the power. Turned the game back on and the bumper worked again. Why doesn't it work with the second screw attached? Is the second screw somehow shorting the switch and the circuitry kicking in to turn off the coil so it's doesn't burn? If this is the case, what's the solution? I'd rather not change the switch if I didn't have to.
Lastly, I noticed something weird with the flippers. It seems when I activate either flipper and release, the coil seems to buzz for a few more seconds, then stops. I noticed this with my finger on the bats when releasing the flipper buttons. I have checked the EOS switches, and they open and close correctly with the flipper movement. Is this normal? I haven't noticed this on any of my other machines before.
OK, scratch this last one. I just tested with the PF up, and it's not the coils - it's the springs that pull the bats back. They vibrate for a few seconds when the flipper closes. I figured I'll leave this in, just for good measure.
