Got a Medusa at Christmas and have been bringing it back to life with great joy.
This is all new to us.
The upper right flipper on our Medusa chatters and will not hold.
Can you possibly provide a direction? Would it be the EOS or coil?

In my experience, it is always the coil that is bad.

I'd sure consider replacing that EOS with that much arcing going on but, yeah, it's acting like maybe the hold part of the coil isn't holding. What happens if you isolate the EOS switch blades, does the flipper move at low power? Or you could try clipping those blades closed temporarily and see if it stops chattering. Don't hold it up though, as you'll burn the coil with the EOS clipped shut.

+1 on what Toyguy said. Need to isolate what is causing this.

If you are concerned it is the coil, which is possible, swap it over to a flipper that is working correctly now and see if the symptom follows the coil. If so you need a new coil. Be very careful to match up the wires to the proper solder lugs or you will create even more issues.

Before you move the coil inspect it for a broken wire lead at one of the solder lugs. That is something you should be able to inspect visually. If so, that needs fixed or may be the justification to replace the coil.

Lastly, you have posted in the EM area, Medusa being a SS game should be in the SS category. Luckily your issue is universal.

Thank you guys.
This site is great.
Regarding the replacement of the EOS, my research indicates that they no longer make this EOS.
I temporarily clipped the blades together and the flipper held. Does that indicate a bad coil?
Thanks again for the help.

Sorry MikeO.
Rookie mistake.

Great call on the loose wire. After careful inspection wire was off.
All is well with the world (for now).
Thanks again guys for the responses.

Sweet! Just picked up my own Medusa and have been working through it fixing things the previous owner didn't worry about. Enjoy!

Glad you found the issue. Your video was quite helpful in determining which advice to provide.
