Game can score either 500 points or 3000 points depending on state of game, like number of drop targets down or number of rollovers. There is a relay marked 500 or 3000, and the schematic shows the same relay (C). At the start of the game, hitting any rollover or any drop target will score both 500 points and 5000 points (not 3000) on the score reels at the same time. This is not correct!

I've traced the circuit but it is a bit confusing within the drop target and rollover sections. There is a switch on the bonus unit that closes, then several possible paths to the 'V' relay, then the 'C' relay, and pulses fron motor 1A to the score reels to score the points.

I suspect there may be a make/break switch in the path that is forcing the incorrect scoring, or a switch on the motor I can't identify. I verified the score reel switches, score relays, C and V relay switches, bonus switch, among others. Also, can't figure how it is suppose to score 3000 points from motor 1A (cam has 5 switch pulses with each 1/3 turn).

Any help with the circuit's scoring path or where to look next is appreciated. I have the schematic.
Thanks, Steve.

Pinbee, thanks. That information helps as to game play. However, the odd scoring (500 and 5000 scoring together) occurred on both 3 ball and 5 ball, as well as player 1 and 2. I'll recheck the score reels again to see if the 100 carryover to 1000 (9th position) switch is the problem.
Would still like to know how 3000 points score from motor 1A. Is there a switch or relay in that scoring path?

Checked the game again today. As Pinbee points out the 3000 scoring occurs only on 3 ball play, and it did correctly score the 3000 points today as the ball crossed over rollovers #1-4, or hit target #5. On 5 ball play they correctly scored 500 instead of 3000.

But the white and green drop targets still score both 500 and 5000 points at the same time when they are hit. This happens on both 3 ball and 5 ball play, for both player 1 or 2.

I confirmed that the 9th position switch on the score reel is adjusted correctly and is not the problem. Motor switch 1B, sugegested by Pinbee, was working correctly as is 1A.

Any other suggestions as to how this odd scouting is occurring, or is this suppose to be 'normal game play'.
Thanks

Had a chance to look at the game today and discovered the following. As previously indicated above the game did not score correctly on 3 ball or 5 ball, or on player 1 or player 2. Several possible causes for the errant scoring were ruled out. However, prior debugging was conducted with the ball count only at either ball 1 or ball 2.

Today I tested the scoring at each ball (1-5) and found that it did score correctly on ball 5 but not at the others. Green drop targets scored 500 points and out hole scored 1000 points until all 4 green drop targets were down, then the out hole scored 5000 points.

I'm getting closer to the problem and now suspect that it may be associated with the player unit. How would this scoring problem be associated with the ball in play? Can someone trace the scoring circuit through the player unit for me. I have the schematic but it's not helping.
Thanks.
