I had the playfield of my Road Show up to look at some bulbs (with the power off). When I closed everything up and switched on the machine I though I heard a coil lock on. I found the right rear diverter coil locked on and smelled burned. I've only owned this game for a couple of days so I don't know the machine's history. The closer I look at it though, the worse it seems. It's in rougher shape than I thought and now this happens for no apparent reason. Not cool. I need some help.
I looked for the transistor for this coil Q64 I think. Not burned up visibly. Not sure if it's worth trying to test that first. No voltage coming from the pin for the solenoid at the MPU connection J130 wire 6. There's about 71 volts coming into the solenoid plug (which I have disconnected to prevent locking it on-see the pic). The coil looks pretty bad. Lots of corrosion on this game. Could it be shorted internally or something? Can coils lock on when they fail? Any advice is appreciated. Thanks!
