Quoted from petebest:

So I’ve got all the complicated based/runs/hits issues sorted on my grand slam.
2 remaining issues, and I think they’re related:
1) All the 500 point roll over switch score correct.
All other roll over switches are score what they should PLUS an extra 100 points. For example - 100 rollover scores 200. 300 rollover scores 400. Does not matter if it’s a non or when lit. Always scores an extra 100pts.
2) when the bases are “lit” they should score 1,000 pts when a ball drops in. They are scoring 2,000 pts instead
I’ve traced everything I can, and don’t see anything out of order. When I manually push the 100pt relay, 100 scores properly. So It’s not the relays fault. I think the motor is pulsing extra but I don’t know how to address that.....maybe it’s not that?
No clue where to go from here.
I appreciate the help!
Pete

Score motor should rotate 120 degrees for 1 scoring event, is it rotating 240 degrees?

the extra 100 pt scoring suggests a contact is not opening which would normally open and suppress 1 of the score motor pulses. The pulses that come of off a 1A contact...

Quoted from petebest:

Ok- so I looked.
The motor is only turning 120 degrees when a score occurs. So that’s out
On motor position 1a; there are 3 switches. All 3 are normal open, and are making excellent closing contact when the motor turns
Any other suggestions?

its the scoring chains off of the 1a contacts. most likely on the 300 pt relay a contact is not opening?
