That’s a puzzler – especially after you made the switch to the “12 volt” coil! A few things however to check:

1 – (Long shot...) Are you certain the condensers are good? Use the ohms function on a VOM or DVM and measure the resistance between the pigtail and the can: On a good condenser when the test leads make contact the meter will show very low resistance. Resistance will then rise over a period of several seconds into the megohm range.

2 – Is the condenser can solidly grounded to the breaker plate? (A poor or no ground here gives a weak spark and will burn points quickly.)

3 – When the engine stopped and the ignition on, measure the current in the coil primary. You should see 2 - 3 amps or. A reading of 5 amps or more means the resistance of the ballast resistor is wrong (too low). Burned points and an overheated coil can be the result.
