As noted above, it is either a mechanical issue with your EOS switch, or a wiring issue between the EOS and the coil.

Compare the wiring with the right flipper and ensure the coil diode(s) are oriented the same.

For future reference, you almost never need to replace your coils for a good flipper rebuild. I avoid it for both the cost savings as well as the wiring headaches like this.

GL!

Could be. I've had a few that were bad out of the gate. This is the 1% of issues that isn't EOS related!

You could have put the original back in unless there was something known bad about it.

Glad it is solved.
