You need to remove brass rivet and remove the thin mica sheet. Cut the metal tabs that are on top of and below the mica sheet so they can not short together. The issue is that the mica becomes contaminated from the metal tabs. This changes the mica from an insulator to a CONDUCTOR. So the mica has to go as do the tabs that make up the fixed capacitor. Once you get that done measure the resistance from pri to sec, should see no resistance between the two coils. Then reinstall.
