I was playing a game and the right flipper just completely died. I have 45 volts on all 3 tabs. EOS switches were replaced a week ago and were working fine until now. Left flipper works fine. What should I be looking for?

When you press the right flipper button, you should measure zero volts on the right flipper coil lug with the orange wire. Does it?
It's probably more likely to be an issue the the EOS switch. If you press and hold the flipper button and manually lift the flipper bat all the way and the flipper stays up with the button still held, then your EOS switch isn't making contact and needs a clean.
BTW, the single orange wire on the end lug is the one that's supposed to come from the flipper button via the flipper enable relay on the solenoid driver board.
When pressing the flipper button, that orange wire should measures zero volts and the brown wire on the other end lug should measures 43 volts indicating you have power across the coil.
It’s working now and I didn’t do anything except move the plunger in and out. The one diode seems to be giving different readings.
Give the EOS switch a clean with some sandpaper to remove any protective coating from manufacture.
Compare your diode readings with the other flipper coil. A suspect diode won't stop a flipper working unless the diode blows a fuse.
Ok thanks. The diode is reading the same now but I think you’re on to something about a coating on the switch contacts. When I compared it to the other flipper, it was reading as if the EOS was open ( I manually pushed the plunger to open it) when in fact it was closed. It’s making pretty solid contact so I will try a little sandpaper.
Over time the solder connects to the relay and connector pins on the sol driver board go cold causing erratic problems like this. If it happens again pull that board out and reflow those connections if you haven't already done so.
Quoted from Nikrox2:Remember - we love this game! lol Right?
Haha. Of course!

It’s a newer Alltek board but I get your point. I should probably repin those connectors. The solder connections at the coil itself don’t look too great either.
