I give the readings for the "Phase sensor in Dizy", OHMS 700-1200....Gap in Dizy of sensor 02-03mm, On what you say i would be inclined to renew Rotor. I say this as you have a good spark from the King lead, One other thing....but sure its OK...check the Dizy is on time with Cams/Crank....expect you have done this....really it should never move....but i remember when i was working going out to a customer who had renewed his Timing belt on Cosy, he had inadvertantly moved the Aux pulley....thinking it was only for the oil pump... engine hardly Ran...OK after i reset all. Just a thought.
The resister in Rotor DOES burn out, ive changed mine twice re-also have Group A coil. Pete.
