Bally 873A - payout reset coil not firing

[frenchmarky]

Game's been working perfect, and I play it just about every day a little bit but today it totally quit resetting the payout unit out of nowhere while I was playing.  I've had the game for many years and keep it maintained.

  I checked, adjusted and cleaned this stuff but no luck:
 -- the single switch at reel stack B
 -- the payout unit '0' switch (opens at 0)
 -- payout reset coil is not open, measures at 15-20 ohms
 -- connectors in rear of cabinet look okay
 -- other coils are working
 -- manually, the payout unit steps up and resets fine

Those are the only two switches shown in the schematic that the coil goes thru so I'm kind of stuck, any suggestions?  Thanks!

Another weird thing is I noticed the winner paid light now stays on even if I manually reset the payout unit.   Even with the payout pawl switch held open with a piece of paper the light stays on, very puzzling.  It's the switch that opens at zero.

*** After cleaning/adjusting the switches a little more, now it's working.  Not really sure how it got fixed though, I'll keep an eye on it.  Must have been one of those two switches.  Also when I was manually resetting the payout unit, I was pushing a lever at the top, but that wasn't fully actuating the reset so that was messing me up a little in testing the reset itself.
