Harman Collins distributor

Do you know if there are any spare parts available for the HC distributor with doble coils ?
And also what kind/size should the resistor have (12V) ?
Any other important to think about ?
Thanks
Michael
 
There used to be a guy here that got into making parts like the rotor for the Harmon Collins dual coil set up. Dzusfast is his handle but he hasn't posted in a long time. Ballast resistors for 1.5 Ohm coils are generally 1 to 1.5 Ohms. A person can use 3.0-Ohm coils without a ballast on 12-volt systems.

Unfortunately I believe that he is no longer with us.
 
The simple answer is to use Ohm's Law to make sure you have about 4 amps going through the points. Use your multi-meter to do some measurements and chose a ballast resistor of the proper resistance. You should be in the ball park for a good running engine.
 
No more parts unless you can find some on the auction site, Dzusfast reproduced the rotor and the intermediate cap. The coils determine weather you need a resistor or not. You can still find the outer caps that work and the points and condensers.
 
You might try Tom Cirello at Cirello Magneto's as he was rebuilding the Harmon-Collins Magnetos for the early flatheads. There might be some parts that interchange between the Mag's and the Dual Coil distributor. He has rebuilt three of the H-C mag's for me over the years with excellent performance.
