I noticed the left sling on my Mr & Mrs Pac-man was sagging awhile ago. When I took a look under the playfield, one of the screws holding it into the playfield had come lose over time.
When the mechanism sagged, it broke two wires that connect the switches on either side of the sling. At this point, the sling wasn't working because (guessing here) the switches weren't connected.
At the time, I figured I could just play the machine with a broken left sling, and then all of a sudden, the sling began to rapidly fire. I turned the game off to interrupt it/stop it. It would only happen periodically though.
I'd mistakenly thought that because the switch wires were broken off that no power was being delivered to the coil.
Question - is the rapid-fire sling coil due to a bad coil/solenoid or something else?
If it *is* the coil, will replacing with a new one from Marco (or wherever) resolve the issue?
