Hello! My fantastic machine is having an issue with the ball return/ball save function on the left outlane. When you hit the center standup target it lights the left outlane which activates the ball save feature. When you drain a ball and hit the rollover in the corner of the outlane a coil hidden under the apron is supposed to punch the ball back out onto the playfield for a one time save. Well this is not happening and I have tried everything I can think of. While testing the game with the glass off depressing the rollover usually does nothing. Every now and again however the coil will partially activate and the rod pushes halfway out of the apron but not enough to knock the ball back or deactivate the one time save by opening it's EOS switch. Sometime it just shudders a bit or moves partially but most of the time nothing happens. Any ideas would be greatly appreciated!

Does the switch under the playfield for that lane have 2 contacts on it? Sounds like it does and one is either dirty or not making properly. A few games I've worked on have been like that and wouldn't score the bonus properly. Cleaning and adjusting fixed it.

Yes it does. Sorry I should have said I cleaned and adjusted that switch under the rollover already. I also cleaned the switch that triggers the bonus light.

Diagnose this circuit with Alligator clip jumper wires.

Thanks! I have alligator clips and a multimeter but I have never diagnosed a circuit before. Would you have any suggestions?

Here are a couple articles about how to use them. If you'd like though we can talk on the phone.

I know when I had similar issue (Fun-Fest, pic below). The part circled in red was not seated in place properly and I also re-soderd the 2 wires (red arrows) to the coil tabs while I was at it. Just a thought.

Ok thank you I will try that as well and advise on my results! It looks like the previous owner had re-soldered it already when I pulled the apron. And did a very poor job at it. The metal rod that actuates the EOS switch appeares to be in the correct place on mine and when tested by activating the coil manually is functioning properly. I also noticed that he has the 2 white wires soldered to one side of the coil and a black wire soldered to the other side. It looks like yours has one white to one side of the coil and then a white and a red to the other.

Fixed! I tracked down the ball return relay (thanks HowardR for the diagram) and cleaned the switches on the relay. That did the trick. Thanks everyone!!
