Details, details.:D
I don't remember ever seeing or hearing that a rotor or button was grounded out except maybe the spark going down through the rotor to ground, so no continuity between the cap coil terminal and ground would be normal wouldn't it? (that answer is yes):D
The fact that there is spark to the cap but not out of it usually means the rotor is either broken, not seated or not turning. (we could call that phasing if you like):D
Phasing would certainly be off if the rotor isn't seated where it belongs.
Phasing being that far off doesn't just happen for no reason so rotor seated and spinning with the motor seems to be the next verification, right?
