Ok. So tonight the VUK under the buildings stopped working. When I lift the PF I can see the ball sitting in the metal hoop that holds it. When the coil fires the plunger does not go far enough to hit the ball, it just falls short. This started all of a sudden. Was working fine up to this point.
I tried bending the hoop down a bit to lower the ball, but then it was not making it up and out. Just up but not far enough to exit.
