I am finally working through a number of issues I have had with this machine. The last one I currently have is on occasion when the top pop bumper fires the middle right bumper also looks to fire. This is very random and does not happen all the time.
I have so far checked the switch gap which has good clearance, checked cables for any shorts (visual around the area). I am not sure what can cause this to happen. Any advice on where to look next would be appreciated as it is one of those things that is driving me mad.
