I meant the connection on the ignition switch. The connector body pulls off revealing spades sticking out of the switch.
The coil connectors (stud and nut) are pretty dependable, although if loose can cause problems.
My coil that I mentioned had connectors that slipped over studs or buttons on the coil. There was a bakelite connector body that held the connectors and slipped around the coil and made both connections at once.
I would clean up every connection that you can and make sure they're all secured.
