Engine Swap

Post by Campbell Tellman » Thu Jan 01, 2026 3:39 pm

We have a 1916 Ford Touring we are restoring. We are replacing the original engine with a later model electric start engine. So I think I can use 1.0 wire from the 8 volt battery to started switch, and then on to the starter motor. Do I need a fuse? My hope is use the magneto for ignition. As to the generator, how do I wire it to charge the battery? Negative ground . . . .correct?
Thanks for the input.
We're excited to meet everyone at Lake George! Our T won't be ready but getting closer!

Your coil box should have 2 terminals for power in. 1 from the magneto. the second for battery ignition from the battery.
Thats a handy spot to put the generator power wire to. Dont mix the 2 terminals up lest you kill the mag.
Its a good idea to keep the generator output low in the 4-6 amp range for 8v. Also adding an ammeter is a good idea to keep a monitor on the generator. Otherwise if there is a failure, the generator will be destroyed before you will know it.

Henry didnt install a fuse. I dont either.
There are others with opposing opinions on the subject.

Go to www.texastparts.com for wiring diagrams. They do not go as far back as a 1916, but you can look at the 1919-25 and see where most of your wires will be placed. I highly recommend a fuse and the diagram will show you where to place it.

John is so right about the ampmeter.
I build mine in an empty coil.
Photos are from a 1912 Torpedo runabout.
The on-off-on switch is for the flasher, the push button is for the starter( I installed a starter relais to command the starter) the other switch is for the lights.

I use a 30Amp to secure the electrics.
