Hi everyone.
First, sorry for my poor english. I will try to be understood.
I have a Gottlieb Bone Busters pinball.
I get some problems with the pinball.
The game is starting well, flippers are working. But during the game, some solenoid don't work, or if the ball fall in a "lock" hole, nothing happen.
The pop bumper didnt work, the kickback didnt work. On the bench test, these two solenoid works well.
when i did a lamp test, everything works. when i did a relay and solenoid test, test testing mode stuck on "solenoid 0" and this solenoid come on and off without stoping till i switch off the pinball.
After i read some topics, i have repin the A3-J3 and the contril driver connector but the problem still.
Also, the driver board is brand new, a rottendog GDB080 and during the first utilisation, the driver board was running perfectly.
Any idea or suggestion?
Thanks in advanced to everyone

Hi Bax1
everything are good in the switch test. All switch closed

Yes, you are right. All switch are open but the through hole (i remove the ball in it for the test and after that all switch open.
Thanks for your siggestions. I will try to see if my control driver connector are ok. I think he is but i will did another test with multimeter. This connector are brand new but maybe he can be the problem.
I will forward the result
Thanks

After some multimeter tests, the problem still!
There is some pictures:
CPU board are brand new
Driver board are brande new

Well, i dont know waht to do at this time????
Thanks to all for your help

I don't have the schematic and it seems realy hard to find on the internet!

After a lot of tests........
The problem still!
When i did a test mode, the test mode stuck on LAMP 0. and clic, clic, clic, clic, clic, clic, till a turn off the pinball. The sound come from a switch or something like this with a sticker on it "Q". See pics

Nope! Still stuck there and the test mode can't go further.
What is strange, is that i was able to do the switch test last week. Well............electronics! Lol

Ok thank you very much!

I did the ground mods........
same problem!
Still stuck on lamp 0 when i did a mode test.

They are new but they were working for 100-150 games.
After that the problems appear.

Thank you

I did 3 vidéos to show the problem so if you want to see this short videos just click on the links below

Thank you very much Schusler

Hi Schusler, no problem and thank to you for your research! I appreciate

Hi ChrisHibler
Thanks for your help.
First, i will buy the manual on the net to understand much better what is the system 80B and for more informations about the Bone Busters.
Second, about the OEM MPU and driver board; when i purchased the pinball the new boards was already installed and i dont know why the OEM was removed from the pinball but the machine were operationnal 100% with no problem.
Third, when i have repin the A3J3, i am pretty sure all the repinning have been done like the original. Wire and connector 1 by 1 to be sure everything still stand like original pinout.
Now, i dont know what to do. Pinball were perfect at the beginning and right now it's a big puzzle for me.
Maybe i'll need to replace the MPU and the driver board with a OEM part. Let me know

I still with the same problem!
I can't repair the pinball...............
Maybe it's really simple to fixed that problem but as i am not a expert, i think i will need help from someone who knows that pinball or Gottlieb system 80B. I am pretty sure someone have experienced that problem and resolved it.........

Thanks to everyone
I have forgot to reply in this post! My apologies........Sorry
Finally, the brand new CPU Board "Rottendog" was the problem. I still wait for a new one which was in the mail..........
Great day to everyone
