Hello everyone. I recently got a Bally Rolling Stones project pin from 1980. It currently doesn’t work. When you plug it in all of the gi lights works but none of the controlled lighting. The displays don’t work nor any if the coils. I noticed that every now and the coils will attempt to work abs a random sound will pop on.
I’m in the process of traded out some of the recommended capacitors on the solenoid driver board. I’d also like to do the recommended mods that pinballhelp.com posted about. I recognize this might not solve the problem and have fully reserved myself to the thought that I probably have to replace this board and the mpu but I thought I’d give it a shot.
I’m curious if I can do those suggested mods on this board. It looked to me that it might be a little different than the pictures I saw. Also I believe I bought the correct capacitors but I thought I’d ask if it was wrong.
Once again I’m giving this a shot fully recognizing I might need to upgrade and do more tests the rectifier board.
Thanks for any thoughts. Here’s the pictures.
Also why Do you all feel this was previously jumpered?
