Working on a Olympic Hockey and I have an issue were player 1 doesn't always return the puck to center ice. Mostly happens when goal is made and then you hit the switch that will bring it back to center. Sometimes also happens on a drain. It is not consistent doesn't always stop in the same wrong spot. Sometimes does reset and goes to center ice.

Player 2 works perfect.

I know that the advance unit is going both left and right one way for one payer the other way for the other player then reverse to reset. I think the advance unit should have a Zero position (center) and I'm surprised when this happens it doesn't keep firing the coils to get to Zero.

Help a little stumped on this one.

I found this basically same issue

Using it to help me but my problem seem to have went away. Also found some more info in the manual. So hopefully I’ll get this cleared up.
