I'm guessing this will be a faulty node board if you have a KISS (Pro) If it's possible to swap the flipper buttons and see if the problem moves that might be worth trying. I can't tell from the manual what sort of configuration the buttons and boards have.

I think it's Node board 8. If you have another dmd Spike game you can try switching Node boards and see what happens.

Pretty sure it needs to be an exact match. Do u have any other dmd Spikes to compare?

Good luck!

Why aint Sten responding on this thread Westin my pants off, i derelicte them balls, why, why does not Stern respond on Pinside .? We should get amswers from all pinball manufacterd like jjp, Stern, HP, DP and so on....... Good luck on that all us semi efterblivna

Yes that is the correct board.

Have you checked your switch gap on the left flipper? Clean the contacts possibly? Try running a switch test.

Did you switch the Node 8 board with another board from the same game you're having the flipper issue with?

Did you set the dip switches to their proper positions on the new board?

Do you have a schematic? The Stern manuals online don't have them anymore.

The point of swapping buttons was to eliminate the switch as a source of the problem. If you somehow swapped only the button and not the switch that activates the flipper then it could be your switch acting up. But since it works in test I think that's unlikely.

I still think it's a board problem. Without schematics I can't suggest where. I can't think of a component failure that would cause it to flip four times, then die.

No schematics come with spike machines, one way of stern saving money and making money on the back end selling whole node boards.

If the coil fires properly during a coil test and not during game when you be using the flipper buttons it's most likely a switch input problem on the node board, unfortunately youll likley be calling stern.

I´m not a SPIKE expert, but I encountered this kind of behavior on several solid state pinball machines.
Normally the coil winding for flipper hold is not working correctly in these cases. Kiss Pro seems to have a dual wound coil (Power/Hold with three wires) for the flippers. The power coil winding fires the flipper up then the EOS-switch turns power transistor off. Since hold coil winding is not working the flipper won´t stay up and EOS will trigger power winding again. After some attempts the CPU ends this machine gun cycle to prevent damage. Maybe you should check with a multimeter if hold winding is powered correctly. If you´re lucky is only a bad solder connection on a coil lug.

He's saying check the resistance on both the hold winding and the high power winding. It should be close to the one you're not having a problem with. If you're lucky, the resistance is good but one of the solder joints is cracked.

Good luck.

First I would check hold winding in solenoid test to verify my assumption with a failing hold circuit.
Hold winding for left flipper should be solenoid 20 in test. Keep in mind that the hold winding will not fire the flipper up,
you may see the bat barely move. You should at least hear when it´s activating.
Compare it with the working right flipper which is solenoid 21 in test menu.

Sonofa, i didnt realize they went back to three lug coils. But there it is in the picture! Figured it was two lug and mosfet driven.
