Farmall 400 wiring (was Re: [Farmall] I'm New On Here

[Mike Sloane]

Believe it or not, you can still buy a brand new wiring harness for the 
400, although it won't be cheap. If you contact me off-line at 
<mikesloane at verizon.net> I can send you images of the pages from the 
parts manual, which will work pretty well. I should point out that the 
later 450 was a 12 volt tractor, and I don't think that you would find 
many differences (electrically) between a 400 and a 450. So you could 
use the wiring diagram for a 12 volt 450, although that is a generator 
equipped machine, not an alternator.

As far as converting the tractor to 12 volts (with an alternator, I 
presume), that is your call. If all the components are in good shape and 
the tractor starts easily on 6 volts, why fix what ain't broke? But if 
you need to start the tractor in the dead of winter, or the generator 
and battery are due for replacement, changing to 12 volts can't hurt. 
The trick with converting to an alternator is working up an arrangement 
where you don't have to hack up the hood. Of course, you also have to 
change out the lights and re-wire the ammeter and coil, but those are 
not big deals. It is your tractor, and you can do what ever you like, of 
course. Just for information, I bought a Super M with a bad battery and 
generator, and burned out lights. For me, the decision to convert was a 
"no brainer", but the hardest part was mounting the alternator. See

for my installation.
