Very nice, I like this set of drawings very much. Now I just need to upgrade to color printer.
Just give me time to Rust and I'll be good as new. :) Wabi-Sabi

I'm not electrical oriented at all, so here's my question. This would be for a 1922 with no starter, and the switch still mounted on the coil box. I don't see any need for the choke coil? Am I correct?

Those are very nice. I recall a friend bringing his T over with wiring problems. He he had installed a new terminal block and it wouldn't start without the lights on. We got out the Service manual but neither of us had good enough eyes to read the fine print.
Thanks Bob and MTFIC.

When did I do that?

The 22 cars would not have had the switch on the coil box and (up to 1926) with no starter/generator would have come with the choke coil mounted behind a blank off on the instrument panel (in place of the ampere meter)as it would still be using mag powered lights.
I know the voices aren't real but damn they have some good ideas! :shock:

Bob has done a great job here.

I love his comment on the first page "... for every absolute fact there are at least three exceptions." :D How true!

Looking at the diagrams in 'order' it is interesting to see 'technology' advance and become more complicated at every step. The 'first' diagram vs the 'last' is quite a change - all step by step.

Thanks to Bob Cascica for this.

Would the later non-starter car, those with the firewall terminal block, have an electric tail light as shown in drawing #3? Or would it just be the oil tail lamp?

As noted by Bob:

After 1916 there are overlaps and many exceptions as to which drawing applies to what year and what model.
As everyone in the Model T community knows - for every absolute fact there are at least three exceptions.


An oil tail lamp would be supplied with non-starter open T's, as there is no storage battery. But in the later years, when the T was around a while, many owners installed storage batteries, so even Ford knew that. The terminal block shown is the 4 lug, and the left side was reserved for BAT, in case an owner installed a battery. This terminal block is for the steel dash, '23-'27 open car non-starter.

1926 runabout, non-electric, would have magneto head lamps, and you can see the oil tail lamp. And non-demountable clincher wheels ;)

Bob, Great work! Would you also consider doing the coil box mounted ign... BATT/MAG wiring in side the box. Thanks for the wonderful diagrams.
