Picked up a Game Show light project.
Fixed all the interconnect board lighting issues.
Has a new system 11 rottendog board because the old one was battery damaged. (problem existed before this board was installed when my friend owned it).
Center coil lugs have 70v
If the backbox mounted bridge rectifier goes to the flippers (i suspect it does), appears to have just under 13v AC in and 6.5v out DC.
All fuses test good out of circuit.
Continuity on all wires from A to B is intact.
Solenoid table does not have a transistor associated with the flipper coils

I've had a lot of system 11's, all projects (which is what i prefer), but i've never had a situation where the flippers did nothing at all.

I'm an electrician, so i can test whatever you guys want me too.

Other issues that i have yet to sort out is right sling doesn't work, neither does one of the pop bumpers. I've yet to look into these issues.
For the most part, this game starts and plays as it should, just with no flippers.
Thanks for any help,
Joe

Edit: Fixed the sling and pop bumper, both just had wires that broke off the lugs.

I followed this video to test the bridge rectifier attached to the backbox that appears to be associated with the flippers. I highly doubt I tested voltage the correct way in my previous post.

I'd say it definitely tests bad.

I was thinking of ordering this one:

Yes, no?

Thank you, that gets me to the wiring diagram that i struggled to find.

I may need new glasses and to use better light. I was following similar but different colors. So there that rectifier is in the manual and it appears to be for lighting, which works.

Doesn't explain why when i follow that test in the video, one direction gives me no reading. But i'll worry about that some other time.

Well, it's fixed.
Might be the most complicated i've ever made a simple problem.
Turns out, in switch test, guess what? The flipper buttons didn't work.
Rubbed the switches together and then boom, flippers worked.
Swapped in some new flipper switches, then changes the EOS switches and wouldn't you know it, it works fine.

Lesson learned, sometimes the simplest solution is actually the solution.
