Farmall A wiring diagram

Leonard Keifer · Jan 12, 2009

Can anyone tell me where I can find a wiring diagram for a 1940 Farmall A with a magneto? My father needs to rewire his.

Follow the link below and click on #4. If he's got a battery and the standard Delco generator, that one should work and it's a lot easier to follow than the one in the Operator's Manual.

If the tractor has the Bosch system, you might have to get hold of a parts catalog to get the right diagram for that.

If you need a copy of the original wiring diagram drop me an email and I can send you a pdf file of it.
