Marahall If I can help if you give me a call. I think I know what is wrong with the generator. Trouble shooting the Model T charging/discharging/wiring issues is easy.

It could be a vacuum leak. I have a some questions. Has the car recently been wet? Did you get caught in a rainstorm or was the car washed just before this problem was noticed. If so did you try and have trouble starting the engine because it was not working properly on all four cylinders? Did the c...

Sorry, belay that. Wrong diagram.
Here is the correct version.

The Ford starting and lighting system is a 20 amp system and should be fused for 25 amps. The circuit where the fuse goes is a #12 yellow wire. Here is a diagram depicting in the notes 1919 to March 1922 Wiring Daigram w-electrics & Magneto Horn.jpg where the fuse should be wired into the curcuit.

No. It is a copy of a original Ford factory drawing T-1891 or T1899 battery to switch and switch to starter cables.

This coilbox and coil depicted above was ony used the first six months of 1913 production. This coil design was first shown to Ford in late 1912. Until that time they had been struggling finding a reliable/maintainable coil solution for early Model T's. Hence the many different types of coils/coilbo...

I believe the more important question is “why did Ford select the initial timing of 15.5 degrees after top dead center for the Model T”? At the time most low-priced automobiles utilized dry cell battery powered trembler coils for ignition. Keeping the batteries serviced was a constant problem and if...

One comment about above mentioned reverse current cutout "cutin" adjustment.
The third brush regulation generator on the Model T should be adjusted for Armature cutin and contact closure at 7.2 volts.
