In my extensive old car electrical reference library I have a three booklets relating to Gray & Davis and the Model T Ford:
1.) "Gray & Davis Book of Instructions No. A-68 Double Unit System for Ford cars". It is important to understand GD made two units for the Model T Ford car. They are fundamentally the same only one uses third brush regulation and the other uses a regulator/cutout. Both are depicted in the booklet and you will be able to tell what you actually have.
2.) I also have a 1921 book entitled "Automobile Electrical Systems" and Chapter III Special Systems for Ford-Gray & Davis which is is basically the same information with about 25 pages describing in detail operation including the two different regulators.
3.) I also have a 1923 book entitled "Automotive Engineering", Section "Electrical Equipment" with a sub-section "Special Equipment for Ford Cars" showing installation of the the "Gray & Davis" 3rd brush regulation unit on a Ford car in detail.
All three have physical wiring diagrams, but I cannot find a good electrical circuit schematic for trouble shooting.
Your welcome to a copy of this information for the copy and mailing costs.

The past is a great place and I don't want to erase it or to regret it, but I don't want to be its prisoner either.

Re: Gray/Davis starter
The type of chain you want for the starter is called "silent chain". Available from power transmission companies. It will work on gears of different thread pitches and different power loads. More power to be transferred just add more chain width. It has been used in automobiles to earth moving machinery. I have it on my Hienze accessory starter on my 1914 T.

Re: Gray/Davis starter
Good info on "silent chain" on this site and perhaps a major supplier. pricey stuff
This link is a guide to selecting the proper chain
