Bad solenoid fun this evening - one by my doing, the other not so sure. But given how infrequently coils fail, it's unlikely this is a coincidence.
I discovered tonight that at some point, it looks like I laid the playfield down on the receiver bar area (bad habit) and crushed the terminals on the right flipper coil. It still worked, but a hazard. Not sure how long ago I damaged this, but I'm sure I would've noticed it while working on it recently. I buttoned it up a week ago and played daily so it's been played on for at least a week.
And the reason I opened it up tonight was to look at the bottom pop bumper - it stopped thumping but still would score. The coil looked toasty where it didn't before. Took it out, and it looks like it imploded...the sleeve is all melted, obstructed, and stuck in the coil. Then I noticed some of that melted plastic poking thru the coil on the green wrapper.
Replaced both coils and all is working again. Wondering if the damage I did to the right flipper coil terminals somehow took out the bottom thumper coil while playing this week. Next time I have the playfield up, I'll check out with a multimeter what coil(s) are 43V daisychained from the right flipper just to know.
