This wont change the amount of flipper travel, only the plunger length and the thickness of the coil stop.

EOS switches are not preset when you buy them, they need to be adjusted for closed pressure and to have an 1/8 inch gap at full travel. If you adjust them for more closed pressure this will make them open up later in the travel stroke and more powerful.

To me the right flipper looks correct. The left flipper looks like it has too much travel from worn parts.

Remember ball traps aren't supposed to be easy.

There is a bracket that the flipper comes to rest on, this bracket can be bent one way or another to slightly increase or decrease the flipper travel. Use this as a final adjustment to match the left and right flipper travel to be the same. When you do this you will have to reposition the bats resting position again.

The spring plate is upside down (green line) when flipped over it will hold the stack to the play field better. Add more spacers (blue line) to lower the stack from the play field until the see-saw is down correctly, then readjust the contacts so it is open when down.

Ok so you need to adjust the switch opposite from my last post, shouldn't be a big deal.

With all yours games you have never replaced a stack switch? You are supposed to save the fiber spacers for just this instance. If you don't have any I can mail you some.

Start by removing the diode from the coil X and measuring the coil X for resistance. Then compare said resistance to the coil resistance chart.

If the coil reading is good then replace the diode with a new one and retest the coil during a game. If the coil reading is bad then replace the coil and diode with new and retest during a game.

Also install the diode the correct direction, the silver band toward the power wire. For this coil the power wire is yellow.

I am no Stern expert, so I don't know all Stern games of this era always used the same flipper coils. Or have the aftermarket suppliers gone to a single style universal coil to reduce inventory. The reason I say this is the Quicksilver drawing will work as drawn if the diodes are flipped 180 degrees on the coil. The key to the EOS switch is that it is wired across the heavy gauge winding on the coil.

When you changed the caps, you didn't change C-28 and C-30 and the header pins. Might start there.

rcbrown316 I have been focused on that.

Relax and have beer!

Playball!!

You need to adjust the EOS switch to have more pressure on the contacts when they are closed. The switch and coil are getting warm causing a loss of power.
