I have a space shuttle that I'm finally getting around to actually dealing with. At some point in time the coils were working, and now they are not.

The game boots properly, flippers work as they're on a different board - but no other coils.

I've checked all my fuses, and I've double checked all the connectors both from PF to backbox and within the backbox.

Where should I start?

Yes, I am getting essentially no voltage at any of the coils outside of the flipper coils.

All good here. This is what happens when you start working on a project and put it aside and start new ones.

I blew a coil about a year ago, replaced it and never rewired a bunch of stuff. Problem fixed. Now time to clean clean clean.
