Flipper rebuild question

<< < (2/3) > >>

Xiaou2:

 I believe the Cap is to store some additional energy, so that even if the game has
some trouble keeping up with the power demands (many coils firing at the same time),
the flipper will have less of a delay.  It might also be to provide an overall quicker response
when flippers are activated.

This is not an electrolytic capacitor, sorry.


--- Quote ---With the introduction of F-14 Tomcat, Williams changed to the parallel wound FL11630 style flipper coil. This coil now used an outside lug as the common lug (where both the low and high powered coil wires were connected together). Also TWO diodes were used and required on these flipper coils. This parallel wound coil eliminated the "back spike" of current when the EOS switch opened. It also allowed the use of a 2.2 mfd 250 volt capacitor to further limit EOS switch sparking and pitting. Now when the EOS switch opens, this removed the high powered side of the coil from the circuit. The low powered side of the flipper coil is always in the circuit, but is essentially ignored when the high powered side is in the circuit. This happens because the current takes the easiest path to ground (the low resistance, high power side of the coil). The low power high resistance side of the flipper coil won't get hot if the player holds the flipper button in.

MameMaster!:
Interestingly-- all I did first was to replace the actual right filpper button and adjust the contacts-- suddenly the "weak" right flipper was just as strong as the left one.

Easy fix!  :cheers:

Jeff AMN:
For the price, I'd just replace coil sleeves with each rebuild.

I had one of these in the gameroom for 6 months or so ("stored" for a friend during his basement remodel). It's a fun and often brutal pin. Theme is a weird one, but the play made up for it.
