f someone has a 830, they may give you a direct answer, but since I do not, I may be able to answer you by knowing how the 6 v batteries are connected. Simple series with connections to tractor only at extremes of the 4 in series or is there a 3rd connection to tractor somewhere in the middle of series, or what?
 
well 4 6 volt batteries would give you 24 volts wired in series so two 12 volt batteries wired the same way would also give you 24 volts.
 
Connect them in series.

Connect a light (16GA) fusible link wire from the "tie" between the 2 batteries to the tractor chassis.

The cable connected to the (-) battery post connects to the large terminal on the starter solenoid.

The cable connected to the (+) battery post connects to the the large terminal on the starter itself.
 
They originally used four six volt batteries all wired in series for 24 volts. With two 12 volt batteries, they also wire in series to get the same 24 volts. The center tie point (+ of one battery - of the other) gets tied to frame ground. Heres a wiring diagram, youre the same except only two 12 volt batteries, center still tied to ground.

That would create a 12 volt dead short in the system.

hy do you say/think that, Walt?
 
Because the center wire is hooked to both the - and the + side of both batteries. You can hook both sides back to the frame on any of the batteries.
 
The little 16 GA jumper wire will not cause a 12V dead short on an electric start 830 or any of the "new generation" 24V diesel tractors, as the 24V starter and generator are totally isolated from chassis ground.
The purpose of the little jumper wire is to allow 12V Acessories to pull 12V from either starter cable to chassis ground.

he + of one battery goes to frame and the - of the other goes to frame. I see no problem, here. 24v for starter & generator & 12v for all else.
 
Walt, if you don't know how a 24 Volt Deere 830 is wired why don't you go lay by your dish rather than criticizing someone who DOES???
 
Walt, certainly someone like YOU could do that, but it's NOT how Mother Deere intended it to be done.
 
I AGREE WITH BOB, the drawing I posted below shows how Mother Deere wired it ORIGINALLY

Youre welcome, the drawing I posted below pretty well covers it except you only have two batteries

It does NOT create a dead short,,,,,,,,,the drawing I posted below shows how Mother Deere wired it ORIGINALLY thats a Deere drawing NOT MY OWN

UNLESS you meant it creates a dead short to frame ground (at the center tie point) ??????????? THAT it does indeed but its does NOT short out the batteries, it ties that center to frame ground so theres two 12 volt circuits to run lights etc., one is POs ground the other Neg ground.

Hope this helps, yall study the Deere drawing and Im sure it will come to ya

Best wishes n God Bless

on't you just love some of these old J DEEREs! They really ought to make a lot of folk happy (or unhappy?) that like to spend all their time bickering about Positive ground versus Negative ground! Can't do that here.......got the best of both worlds. Got 'em both +/- all on the same tractor.
:lol:
