While my hand heals from surgery, I’m slowly getting back into doing things. I started out this weekend by doing something small and light, and for myself. I’ve had an unrestored spare set of late 1912 Heinze ignition coils for my [October 1912 build] 1913 Canadian Ford. I decided to rebuild them. Since my car is a very unrestored cosmetically, but very well maintained, and running car, my coils won’t be visually mint condition but mechanically they will be like new. Completely gutted with new primary and secondary windings used for the later Ford model T coils available from Lang’s or Snyder’s, and new correct capacitors. The original contact points have been carefully removed and new ones installed. Now that they have been calibrated on Mike Kossor’s awesome Heinze edition ECCT unit, I will be able to fill them with tar and they’ll be as good as new for the next 100 years!

These coils work very reliably! The set currently in my car has been giving me flawless performance for quite a few seasons with thousands of miles!
My grandfather bought this car from the original owner in July 1956 who purchased it new in November 1912
