" I think my new resistor delivers about 5.5 ohms resistance, the coil shows about 6 ohms across the primary and 8,800 ohms between primary and secondary."

You should have a total of about 3 ohms total with resistor and coil primary

I have seen alternator conversion kits come with 5.5 ohm resistors. They will not work satisfactory.

6 ohms is unusual for coil primary. 6 volt coil should be about 1 1/2 ohms and direct 12 volt coil 3 ohms.

Is 6 ohms the reading on your ohm meter with probes on coil + and - posts? If so short the probes together and subtract that reading from the 6 ohms across the coil. That will give coil resistance. It is not unusual for ohm meters to show resistance in the probes.

8800 ohms in coil secondary winding would be in normal range. Resistance in the probes is insignificant at higher resistances.
