I changed out all of my insert bulbs for LEDs this evening. Upon playing a test game, I realized that my flippers are no longer working, nor do the 24v bulbs light in the lower playfield. Fuse F4 is fine, and I even replaced it with a new fuse to be sure. Everything else is working fine, pop bumpers, slingshots, etc. I was thinking maybe this is a plug issue, but I checked all the plugs that I could see in the cabinet, and all are plugged in. Power supply in the cabinet has been rebuilt, and I am using a Rottendog power supply board. Ground mods, as well as pop bumper driver board mods has been done. If I remember correctly, the flippers stopped working for a spell when I was initially repairing the pin. In that case, from what I remember, they started working on their own. Pin has been working fine for the past month or so. Any ideas?

I was thinking the same thing, but it's not just the lower flippers not working, the main ones aren't either.

That makes sense! Thanks, I will check that relay. Yes, ground mods are done.

Thanks u2sean! Found the relay, and fixed the problem.
