I have a few suggestions for the cause of weak flippers, some may have been mentioned before and if so, I'm sorry…
o Bad EOS switch that doesn't let all of the power through to energize the
flipper.
o 'Expanded' flipper coil. As the coil gets old, or fried, it expands, putting
more friction on the shaft. Coils should always be replaced if a new sleve doesn't slide in easily.
o 'Mushroomed' shaft. From the constant pounding on the coil-stop, the end of
the shaft mushrooms out. This causes friction between the shaft, and sleve.
o Weak return spring. If the return spring doesn't pull the shuft all the way
back to the resting position; then when the coil is energized, the shaft only moves a bit, resulting in a weak flip/kick.
o EOS being activated too early causing the 50v to cut out too soon. o Bad transistor on the driver board that doesn't 'open' as much as it should. o Flipper rubber that is put on so badly that is rubs against the playfield.
(Yes, I have seen it!)
o Any slak in the linkage assembley. Sometimes the link wears out around the
pivot points.
o Steap playfield makes it seem like the flippers are weak. o Misaligned flippers can make it seem like the flippers are weak.
That's about all I can think of now, I hope it puts your little minds at ease!
