Quoted from PinBobF:Hello all! I recently purchased by second pin and first Flash. So I guess I’m now part of the club! I am having a weird issue that I hope someone can shed some light on. The issue is while the ball is on play if it hits a pop bumper or sling (anything with a coil) it will randomly advance to the next ball while the original is still in play. It doesn’t do it every coil hit, its random. Eventually it advances to ball 3 and then game over all on the same ball. This happens on the original board as well as a new rotten dog board which I received with the pin purchase. I’ve updated the power board with the capacitor kit from Big Daddy as well as installed the Inkochnito bridge board. Those updates didn’t fix the issue. Reaching out to see if anyone has had this problem or knows how to fix it. Thanks in advance!
Put the game in the switch test and see which switch number appears when you activate the count switch of the pop bumper or slingshot.
Do not activate the coil switch or your coil will burn if you hold it too long.
Maybe a diode is broken or shorted in the switch matrix.
Remember, there are two switches on the special solenoids like pop bumpers and slingshots.
Please see who these work before testing this.
