Well I tried to rebuild the lower right flipper today and It was a fail. The cap exploded after playing just a few min. I went from the blue FL23/600 to the proper FL-11630. The cap that was on there was not the larger yellow cap that you normal see used. I did not change out this cap as it came this way. The cap is attached across the EOS switch. And was not touching any other metal piece. As you can tell by the contacts it was past time to upgrade this flipper.

The lower left flipper also has a small cap instead of the yellow one that someone else had switched. I have not rebuild the left side yet.
Any ideas why this happened.IMG_5955 (resized).JPGIMG_5957 (resized).JPGIMG_5956 (resized).JPG

How do you tell if a cap is polarized or non-polarized?

Thanks for your help I will place an order and replace both caps on the lower flippers. The other side has the same type.
Will it hurt anything to play the game with the cap missing?

Well I was able to get both of the lower F-14 Tomcat flippers upgraded to the better version. Does make a difference in play. Worth the money but a pain to solder the wires on.

Now on to my flight 2000. Is there an upgrade kit for it's flippers? I have an issue with the wood screws have come loose that attach the flipper bracket to the bottom of the playfield. How do I go about fixing this? Looks to need new holes drilled to hold the bracket to the playfield or maybe plug the old holes and then put in new screws.
