I'm having a problem with my Rollergames where the right flipper fuse is blowing
- It does not blow during normal gameplay
- it does not blow when held.
- it blows when flipped rapidly (such as to enter a high score name)
- Left coil was replaced when shopping game, the two right coils were not replaced.
- Flippers are newly rebuilt with new EOS switches and caps
- The fuse is the correct 2A 250v slow blow fuse as called for by the manual and used on the left side as well

I get 5 ohms across all 3 flipper coils (including the brand new one on the left that has no issues)
When flipping I get stable 65v on the left and 59v on the right when tested at the coil

I have double checked my EOS switches and verified they are properly gapped and functioning correctly
Any idea where to start troubleshooting?

Resolved. Separated coils to isolate the issue to the top right flipper. I found that the wire on one of the lugs had frayed and no longer had a stong enough connection to handle the current. Snipped off a half inch and resoldered. Works like a charm.
