Gottlieb Bronco Bonus Help

[GameDoktor]

Hi,
I picked up a very nice Bronco that doesn't score the bonus after each ball drains.
It only scores 1000 points each time. The game plays and seems to add correctly to the bonus ladder. The 3000 pts score correctly. It is the same for multiple players.

The bonus unit stepper advances ok. When the reset solenoid is manually pressed it goes immediately to its reset position. Should this stepper mechanically decrement? (parts missing?)

I've checked relays E and J.

For example how does the machine know that 6000 points should be added to the score.

Any insight would be appreciated

The BONUS UNIT should NOT reset, it should step down one step every time
the SUBTRACT BONUS UNIT coil energizes. Check to see if the arm that
catches on each step is gummed up / stuck or perhaps a spring is missing.

It is fixed, thanks for your suggestions. The arm that catches on each step was way out of position. After correcting that It works as is should. I also looked at the credit stepper to find its position.

Excellent. Nice job getting that fixed.
