1974 Bally RoGo Bonus Scoring Problem

[debaufam1]

I have a 1974 Bally RoGo that seems to be having problems with scoring the bonus points. Everything else works great and the bonus just stopped working. The bonus lights light up as if it were scoring it, but it does not show up on the actual score. And now the score returns to 0 when it reaches 1000.

Any suggestions would be great, thanks.

does the problem exist on all 4 players? its possible just the 1st player is faulty.

I have a similar problem with my Bally RoGo. The bonus count does not come up to 1000 (comes up nothing) but ONLY for the first player AND when the credit button is first pressed. The bonus count properly resets to 1000 for ALL players thereafter - it is just for the first ball in play this occurs on.

I have the schematic but can't seem to follow this one down. Anyone have ideas?

3 hours into I finally realize that 'Outhole Relay' needs the ball sitting in it which doesn't happen when playfield is tipped up - DUH! Note to self - remember when troubleshooting to put playfield down and ball on. 'Problem' went away - works great!
