Hey guys,
All of the sudden the mech that releases the physically locked balls in the top-right of the playfield is not working properly.
The coil fires and voltage at the coil is measuring 67V (is this high? thought it was a 50V circuit?) The coil fires and "opens" the release mech to release a ball, however, the issue is that the mech does not return to it's originally position so that the next ball in line can move up to be released. I don't see any kind of "return spring" on coil assembly so I'm at a loss for how the plunger is pulled back out of the coil after the coil powers off.
Default position (before coil fires):

Coil fires to open up the mech to release ball but it gets "stuck" in this position and blocks the next ball in line:

Thanks for any help you guys can provide.
