Last week I get a package with 6 Heinze 1907 Model R coils to make them buzz again as they should.

Found the points at Langs and will use the brown capacitor they are selling.
In two of these coils the hight tension coil is shot, I will replace it with good parts out of some ford coils with bad wood.

Now my stupid question:
What is the current these coils should be set?
Should I set these coils with a HCCT or should I use a 6V battery to set them? Model R engines have they no magneto as the Model N?
The switch on the coil box said B1 an B2, does this mean battery 1 and battery 2 ?

Thanks

B1 and B2 do indeed refer to the two banks of batteries.

I set mine to 1.3A, as I would a Model T coil. No need that I can see to use any other setting.

As for the points, I removed the actual contact points from Model T coils and installed them into the Heinz point assemblies. They all work great!

google "MTFCA Heinze coils" For the Model T type, what I is read in the postings it would be something like .8 -1.0 for original windings. I would guess the pre T coils would be about the same. If you are changing the windings, that might be different.

Adjust the coils for equal and consistent firing Time For optimal engine performance; not coil current. PM if you need more information on how exactly to do that.

Thanks for trying to help me but,

I have a little experience with the rebuild of the early model T Heinze, Kingston and J&B coils but they all use the model T magneto to buzz in the car. I made a little bench to set the coils by set of four at a time on the HCCT and make them work at 0.8Aac to 1Aac.

During the rebuild of these 1907 Model R coils, in two of these coils I had to change the High tension coil but kept the primair coil original.

My concerne is, as the model R has no magneto and using only battery for the ignition, should the current set lower for giving the battery longer live.
I can make these coils buzz on my HCCT at about 1Vac by a current of 0.6Aac but is this right?

I rebuilt seven of these coils for my early '13. I used Lang's primary & secondary coils for regular standard coils, plus the new Heinze points. I made wooden housings to hold the windings inside the coils. They work quite well. Potted with tar when completed. They took a few settings over time to get the points to settle in as R.V. Anderson indicated to me that they would. Mine seem to work very well set at 1.0 amps for whatever reason. I made an adapter to test them in my HCCT and a Strobo-spark unit. Before I potted the coils I decided to re-use the wire cores from the original Heinze windings by harvesting what I could pack as tightly as possible into the new cardboard tubes in the primaries. Here's the coils operating below. Quick video from Youtube link:
