How could my faithful El Dorado fail me during this stay-at-home madness!?
I was playing along happily when the ball got stuck behind one of the top drop targets. I powered down, slid the glass down a few inches and freed the ball. But when I went to turn the power on again, the machine didn't want to complete the reset. The "spinny-thing" on the floor of the unit (picture below) just goes around and around -- never stopping.
I counted something like 4.3 zillion wires and 3.1 gigaswitches on the spinny-thing - so I sensed immediately that I was in trouble. I took a quick look at the scoring reels as I read here that sometimes they don't completely zero and the machine might continue to attempt the reset. Nothing seemed obviously wrong. I powered down/up a couple of times, but as soon as power is applied the spinny-thing starts rotating.
It seems like a strange coincidence that the stuck ball might have caused this.
Question One: What is the correct name for the spinny-thing?
Question Two: Any ideas where I would start to solve this problem?
I'm a mechanical engineer by training and have replaced flipper coils and other simple stuff...
