Are your eos switches good and making contact. Cold solder on the flipper board.

System 11 doesn't use transistors to drive the flipper, it's a direct/high voltage connection through the cabinet switches.

Yes. Replace the EOS if you haven't yet and are having any flipper strength issues

Yes. The voltage has to pass through the contacts. If it doesn’t it will act Normally open and the coil will be constantly at low power

Make sure you check your other one as well.

May try to resurrect an old thread here - but I’ve owned two RK’s (one I bought then traded off quickly - it was LED’d and seemed to have much more power on the flippers , slings maybe even the pops idk )

Anyhow I kept my original one and traded this other one because of playfield wear The other stuff I can add. Or so I thought

What’s the trick to getting more power ? I know older EM’s you can tap off the transformer on a different tab. But for this one ?

Coming from any of my other games these flippers both seem weak. And again the slings seem the same way.

Just put more powerful coils in ? Think someone just hot rodded this other one before I got it?

thought I’d ask here first
Thanks!

Have you rebuilt the mechs yet? Connectors in the flipper power chain can also help. I don't remember if this era can be high tapped
