Do your new coils have diodes on their lugs I'll take your word for now (for science) that it literally came with capacitors and not diodes - so this is a separate thing, but make sure your coils have diodes pre-installed across the lugs. I think if they didn't it may just do it immediately though, so that MAY be ruled out. If you replace the fuse and play a few more games, will it blow again? The thing with fuses is that sometimes they're a little old and you may find their tolerance to be a bit wacky - meaning sometimes if you blow a fuse and replace it it won't blow again. And if it does, it's very cheap to just throw another in assuming you have a few on hand or near you in a store...

Somebody else may be better off chiming in on the capacitors, I'm honestly not quite sure on that. All I can recall about capacitors under the playfield in solid-state machines is that they were used on old Ballys to make the playfield switches more responsive - I don't think I've ever seen them used on flipper coils. Makes me wonder if it's for the end-of-stroke switches? I don't think it would be for the coils themselves, that would be strange.

(QUICK EDIT: I was also thinking cabinet switches as a possibility, but I just read ForceFlow's first response, there ya go! )

The capacitors help prevent sparking on the EOS switches. This helps keep the EOS switches clean. WPC flippers were designed to include the capacitors.

The reason why they are probably missing is that after long term use, the leads on the caps tend to break off due to vibration and movement over time. So, if someone didn't have replacements on hand, they may have just bypassed them.

Missing caps did not blow your fuse. More likely is a problem with the EOS not opening properly or flipper wiring shorting out.

Always better to have the caps on the eos for any DC game that doesn't have computer controlled flippers.

Not quite technically correct. WPC spans both pre-fliptronic and fliptronic flipper designs. The caps were included on the pre-fliptronic WPC games from FH to PZ. In 1992 on HS2, when they switched over to the fliptronics design, they eliminated the capacitors.

Hey just bought a T2 and it was missing the yellow caps on the flippers. I was just wondering if these will work for the time being provided I clip the leads and replace them with shielded wire from the cap to the switch. The values are the same but the casing is Mylar not metalized polyester
