I'm not getting any high power from the coil on the left lower flipper. It just hums when I hit the flipper button.
If I manually move the flipper up, the low power does work.
The flipper is wired correctly and I have the correct voltages.
Any ideas why this is happening?

Fixed the issue.
The first set of eos switches had a weak connection. Meaning I didn't have the contacts pushed together with enough pressure from the stiff backing leaf.
This allowed enough power through to make the coil hum, but not enough to drive itself.
