I had another weird issue crop up on my route game today. I went in to fix the trough ball switch 1, as the microswitch had completely failed. Went ahead and replaced it and went into the switch test, everything is working perfectly, including the new switch. No switches stuck on, every switch reading fine. I go ahead and play a game, and get What! started and complete it and start the multiball. The whole time I am wondering, where is my second ball that dropped from the upper playfield? Then I started to smell it. That dreaded smell of a burnt coil. Turned the game off and lifted the playfield to find that the coil that controls the inner orbit up post was completely melted. Apparently it had locked on during that game until it fried itself.
I went into the switch edge test to see if something was stuck on, but nothing was. So, I went ahead and disconnected the coil so people can still play it tonight. It is possible that I just had a bad coil that needed replaced, but before I put a new one in, I thought I would post here to see what people thought. Any ideas what might have caused this? I only have 1 replacement 27-1200 coil, so if I install the new one and it does it again, ill have to wait a week while new ones get shipped to me, so I want to make sure I have done everything I can on my side before I put the new one in.
