Hello, I recently acquired a bally hokus pokus and am new to pinball machines and trying to work out a few kinks. The main issue that I am having is double bonus is not coming on. It was working but slowly started to not work, sporadic at first now not working at all. The solenoid appears to be good – its just not getting power. The ABCD series Relay does trip, when you get A B C D but wire (75-6) does not seam to get power. I can’t seam to figure out how this wire gets power. Maybe (43-1) or (45 -4). Any ideas?
Also what does SCM stand for?
Thank you

If you manually close the double bonus relay, does it stay energized until end of ball?

Are you sure you're looking in the right place for the other end of that arrow in the first pic? Can't see the coordinates in the cropped images, and no schematics are on ipdb

Yes, if you manually close the double Bonus solenoid it will stay energized until the end of a ball
I am a not sure at all- I am looking at the right place- I have the entire diagram but cannot attach because the image is to large

I created a link on my google drive - see below

(might have to download then zoom in)

thank you

I think the schematic is missing an arrow on the other end of the wire you're looking for. You should probably examine the path shown in red:

Any one of the four Score Motor switches could be dirty or not closing properly.

Note that the color decoder ring is on your schematic. It will make it easier to find wires, switches, etc. in your game.

To find the Score Motor switches on your Score Motor see:

Thank you MarkG, I thought for example "5B SCM", was in reference to the grid location on the schematic- that link is extremely helpful
