After doing a quick search on Pinside and Google Groups, I did not see a posting about this issue. Knocker goes off twice with a slight delay between the two. Numbers are correct, credit wheel rings up both. Logis on the schematic seems pretty straight forward. Four ways to award credits-coins, high score, hole special, and match. I haven't spent a ton of time looking at all these circuits, figured I'd throw it out to the group if someone has encountered this before. (I never have!)
TIA

Yes, I think DF is on to it (as usual!). I just watched it as I simulated a match with the hood up. It awarded the second credit as the motor came around to the switch again. Will investigate the O relay further and see what I can find. Thanks for the quick responses guys.

Brain cramp here. 'O' fires a second time (causing the second replay), but I'm not sure of the timing at game over that is causing that. Assume ball count stepper should go to 6th position and cut power to all those functions.

Forgot to mention the game is set to 3 ball. It takes a bit of time for the game to step past the 4th and 5th ball positions on its way to 6th (game over) position, so that is giving a couple extra rotations of the motor. Of course this shouldn't matter (it was working correctly previously), but reverting back to 5 ball play gives only one replay for match.....so the problem is only in 3 ball mode.

Checked out the 1d switch, DF, looks fine. The motor does two thirds upon ball in outhole on 3 ball(close the 1d switch twice!). It only does one third on 5 ball (closing that match replay switch just once). I assume it should just do one third on 3 ball? Looking at the schematic now, but my eyes are bugging out staring at it......

Alright, TGIF, time for a drink. I think this was related to the player unit. I had trouble with it yesterday. It had been serving an extra ball at end of game, as one of the shoes was not making proper contact. That might have caused this peculiar issue. As the player unit was briefly stopping on ball 4 in three ball mode. I cleaned/lubed the snow shoes again and now it goes straight to 5th ball (giving one match) then to GAME OVER! Which is what I declare this thread. Hopefully if anyone has this issue in the future, it will prove helpful.
