Vid, is your picture flipped or rotated?
Reason I ask is that I am having a heating issue with an upper flipper coil on my D&D machine. The coils on all three of my flippers are A-24-570/34-3600's. Not the PinCoil brand. I have never had to deal with the lower flippers. The upper flipper coil is new, installed a couple of months ago due to a similar over-heat issue, which at that time actually did blow the fuse (more on that a bit further down in this post). I suspect wiring, but as I look at it, oriented in the same manner as your picture shows, the bands are reversed on the diodes relative to your picture, as you can see here
I'm trying not to overthink this, and I hope I am being somewhat clearer than mud but it is perplexing. And I am beginning to wonder whether it is wired properly, although color wise, the other two flippers and the respective wires are soldered to the coils in the same orientation as the upper flipper.
But only that upper flipper is getting hot. No other coil on the game, not one, even gets warm under extended play. Or if they do, by the time I lift the playfield to check them they have cooled off. The upper coil does not cool off quickly. It's almost as though there is a continuous current feed.
It got so hot last night that the game threw a fuse message on the display and stopped. After checking all of the fuses visually and with a DMM, not one fuse in the backbox or under the playfield was bad. Power off brought the game back up in a ready to play status.
Anyway, the thick/thin 43 volt tab looks like it's in the middle, the thin is definitely as your picture displays, and the thick wire is on the left. Does that sound right? I have looked and looked and looked, and I can not see any indication that the thick/thin wires on these coils are oriented as your picture shows.
Oh btw, disregard that chewed up wire, I did that last night (slipped with the iron in my hand) when I put a new switch in. It was getting late and I called it for the night. That wire is going to be replaced today.
