Hi everybody,

The right flipper on my Harlem became weak on hold after adding a new solenoid board (ultimate), a new MPU (ultimate) a new rectifier board, a new flipper assembly and a new button switch.
So I replaced the new coil by the old one, the coil stop, even the base plate of the flipper assembly (I noticed that the manufacturing precision of the new one was not as good as the original so it might affect the angle of the stop.).
Everything is else is working on this machine. I’m stuck. I have no idea what to try now. Could someone please suggest the next step ?

Thank you for your quick help. The right flipper hold but when a relatively fast ball strikes it, it is pulled back and then hold again. The left ones are clearly much stronger, a ball with similar speed has no effect on them, they hold strong.
The whole right flipper assembly is new, including EOS. The button parts and its switch are new and I cleaned this machine for hours.

(By “hold” I mean stay in upright position)

I double checked the button switch and the EOS switch, they are new correctly adjusted, I bought the special leaf tools to adjust my switches.

Oh you found it! The gap was wrong. The force of the bent leafs were pushing back the flipper. Thank you very much. Have a nice weekend.
