This is my first EM machine so be easy on me.
Basically, I am having an issue where the machine turns on, you press the start button, it sets all the scores to 0, and then it either starts making a loudish buzzing sound (which will normally stop if you kick the ball into the play lane), or it will keep rotating the score motor.
So far I have cleaned all of the plugs and made sure they are seated correctly but I am not really sure where to go from here. Would be very grateful for some tips to start narrowing down the issue.
