Monte Carlo 77 code when I hit the bonus game

[shebaatkins]

I cleared and reset this game. It gives me a 77 code when I hit the bonus game. I have the progressive turned off since I see no progressive screen. Any help I can get would be appreciated. I usually work on IGTs. 

Thanks so much,

Did you have the cable plugged into the left side front of the MPU?

I couldn't zoom in on your picture of the MPU to see what mains you have, U28 and U43. Can post a close up of those chips?

[shebaatkins]

Yes the plug was plugged into the mpu. Pics of mains...

I would like to add that I put those mains in because the other mains that it had were actually clear chips. So it stands to reason maybe they are the incorrect ones. Also would like to add the wheel never stops spinning on start up.

You need 2005 mains. DS1 - all switches on -EXCEPT #5 = OFF. You need a set of removeable clear chips. After you do a clear, keep door open until the bonus wheel has finished calibration. Bonus wheel calibration happens after the reel calibration. Then press the red service button to far left on the outside of the door on the button deck. You should get 50 , door open. Should be ready to play.

Just to clarify, I need different mains?

I switched the mains with my only other Bally 6000 and switches on ds1 as instructed. The machine works great now.
