So I'll start off by saying i do not know much about EMs other than replacing basic playfield stuff, i work on 80's and up with no issues but EMs just always seemed like a lot to dive in to. We just got a Surfer in at work. When i power the machine on all i get is lights. Found a broken solder tab on the "AX Reset Control Relay", when i attach that back the game goes in to an endless cycle where the motor on the bottom left just spins and the stepper in the backbox does the same. the AX relay just stays on, and the Start relay keeps firing. If i dis engage AX it will kick a ball out and coils will work, but as soon as the ball hits any top inlane, it goes back into that cycle again. I honestly have no idea where to start on this or what tp even look at so anything would be helpful.

I know the coin switches and start button are good bc I checked those when I seen the start relay going off. I guess I'll look at the score reels and see if I can find the issue there.

I know if i add points manually to reels it will zero them out but the motor etc still does what it does in video I linked above. I wont get to look at it again until Tues. I'm guessing the reels r the culprit but probably not the whole issue who knows

I'll try that tuesday and see what happens, thanks for an ou there possible solution.
