I thought I'd share this nice Model T wiring diagram that someone did. Unfortunatly, I don't know the source or I would give them credit. I don't believe it's a Ford drawing.
Does anyone have a wiring diagram for the first year engine, with the wiring in the bell housing for the magneto? and or the hand cranked magneto for starting?
Here you go, this is the diagram for a non-starter Ford, up to 1915.
and here is a diagram for the first magneto powered headlamps and horn Fords, 1915.
There is no wiring in the hogshead (bellhousing) in a Ford, only the leads from the coils which are copper strips soldered to the contact terminal on the coil ring.
The first drawing is just what I needed on Wednesday! The one I had was way too tight to follow the wires.
