Good morning,

We changed the power board in the past so I played many games but once the pin restarted so I continued playing and then I smelled that something was burned so I turned it off. After some time I turned it on and now I have these problems:

The biggest problem is with both cannons. They are working correctly when I make the test but they don´t work during the game. It works same as when you turn them off in the menu so they are not used in the game and you don´t earn points during Battle Simulation.

I have also next problem. When I turn it on the ball is shooted by the plunger then it fall down between the flippers and then it is shooted again. This is still repeating until you start the game.

I am sorry but I am an amateur.

Thank you for the help.

Good morning Schwaggs,

I am sorry for the late answer but I have to always wait for my friend who can repair electric parts. You were 100% right. The problem was in Aux board which was damaged and there was burned diverter coil. I have not seen this before. The plastic part was melted inside. There was also damaged fuse so my friend completely repaired Aux board and we replaced the coil + fuse and everything works correctly including cannons.

Thank you very much for the help!

Do you mean the wire which gives power to the coil in A-14615 1-Bank Drop Target Assembly?

Thank you.

I think that we checked it yesterday but I am not 100% sure so I will do it today.

Don´t you please have experiences with building new 8 Driver board? It is also damaged in the second STTNG but the previous owner repaired it wrong so it is not possible to repait it correctly. I know where to buy all parts but I don´t know how to build the printed circuit.

Thank you.

Yes the pin is working correctly but we have one more STTNG so I need to make new 8 driver board for him. I have got already some informations about it so I will try it.

I have checked the tieback and it is connected correctly.

Thank you all for the help!
