Hey all! Im having some difficulty resolving an issue with Scared Stiff. She started spitting multiple balls into play and when i reboot i get the “check opto trough, 12v and wiring” prompt
Here is what ive done so far:
ive reseated all connectors: nothing changed
ive had the mpu board and underplayfield opto board proffessionaly checked: no issue
ive replaced opto transmitter and reciever trough boards: problem persists
ive checked the wiring for breaks: i see nothing
all trough optos switches show filled in test with the exception of the ball jam opto
game will not start until i lift the playfield to trigger ball jam opto and then it proceeds to spit out all balls two or three times, subsides andthen a game begins. Typically first ball will run fine with no extra balls being thrown into play Ball two will start kicking balls out randomly.
I have the 12v daughter board installed to remedy the random shut down at stiff o meter completion. Led on board is showing a clean 12v
Am I missing something? This is driving me nuts.
Thanks in advance for any and all suggestions!
