Wayne;
Look at the terminals (posts). If they are diagonal it is 6 V. If they are on the same side it is 12 V.

Wayne,
Does it have a battery fitted? If so check to see which voltage.
If it has any lights - even an idiot light (oil pressure warning) check the bulb rating.
Does it have a starter to check the voltage from it"s number plate (remember a 6 volt starter could be fitted to a 12 volt system).
The voltage regulator should have a designation on it. Is it a 6 or 12 volt coil? If a 6 volt, is a ballast resistor fitted?
Perhaps an operating manual might throw some light on the subject?
The other posts have pointed you in the right direction and all you should need t do now is verify what you actually have.
You may even be unlucky enough to have an 8 volt system!!

I was not able to make out any info on generator. The coil has 6v on it and the sealed beams are six volt so I going with 6volt.

I'm hoping my operator's manual will arrive soon.

By reseaching on the internet it looks like the 6 volt battery should have the postive grounded.

My father-law has the postive going directly to the starter.

Can you verify the battery installation for me?

Wayne: I presume you found the right page giving you F-140 and I-140. The listings you get there are the beginning serial number for each year the tractor was manufactured. In your case 63 beginning number was 21181, and beginning number for 64 was 25387, thus all tractors in between are 1963 models.

Your new to these forums, am I right? When you respond to a particular person, click on the word reply in the corner of his or her post, then that person gets e mail notification of your responce. I just stumbled back on here by chance. Bus Driver probably hasn't done that yet. Now the person you are responding to has to have checked that little box that says Email Notification. I always check that box, then every time I go online I have an email notification if someone responded to my post. There is also provission there if you wish to send that person a personal email. Hope this helps.

I looked under the serial number section on forum but could not find it.

Help me out! I'm new.

Tx,

Wayne

Wayne: You have to go to Farmall and International section of the serial numbers.

First thing, I feel that you are not personally trying hard enough. From the serial number list on this forum (accessible by you), your tractor seems to be a 1963. So most likely, it has a 12 volt generator. Look at the number on your generator. If the number is 1 100 401 or 319 622 R91, it is 12 volts. In 42 years, who knows what might have been changed on your tractor? If your generator has different number, post it here.

Bus Driver: My 1963 Farmall 140 is very little newer than Wayne's. My 140 serial number is 22157J. When I bought the tractor the previous owner had most of the electrical ruined. 6 volt battery was stone dead and wouldn't take a charge. Grnerator, regulator and ampmeter were toast. The tractor did have a 6 volt coil. I still have that coil but not sure it is any good. I still have the generator and the number is 1100042 9E5, Delco. I assumed at the time that tractor was 6 volt, however I have no idea what was original and what may have been replacments.

I changed the tractor to a 12 volt alternator, bought a 12 volt coil, 12 volt battery and a new ampmeter. The ampweter was the last thing I replaced and had to do that to get tractor to run. I must admit, I really never looked at the lights, one was missing completely and I automatically replaced the sealed beams in the other two with new 12 volt. I have since found a matching light.

I thought when I bought this tractor it was 6 volt from the factory. It was owned until 1990 by the guy that bought it new. Some hot shot businessmen bought his farm, equipment included. In roughly 12 years these new owners were never able to get the tractor running. It was stored in a heated warehouse since 1990. My opinion, these guys were cheap, they changed little or nothing, hired servicemen not playing with quite a full deck.

A friend and I went to pick up the tractor when I bought it back in 2002. We went armed with fresh gas, good 12 volt battery, points, condencer, cap, rotor. With fresh gas and the 12 volt battery we had going in 5 min. and it ran long enough to get plow and disk and load all on the trailer. We hauled it 100 miles in rain sleet and snow, and it wouldn't start when we arrived at my place. By then it was damn cold, thus we didn't try very hard. Just started 130 and pulled it off along with plow and disk.

As I said, my thoughts were this tractor was 6 volt from factory. What do you think?

Hugh, I do have a 140 parts catalog, but it is not in the building with my computer at this time. For some years, the generator on all models of Farmall was the same. For that reason, I looked in my Cub parts catalog, which I happen to have here. Cub changed to 12 volts during 1962. As you may know, Cadillac changed to 12 volt about 1953 and by 1955, all GM autos were 12 volt. GM owned Delco at that time and for many years after. I have assumed that Farmall continued with 6 volt until (1.) Delco absolutely discontinued manufacture of the 6 volt generator or (2.) Farmall depleted their inventory of 6 volt generators. The 100042 generator does not show up in the newest Cub parts catalog. But that number instinctively suggests a 6 volt unit. I had further assumed that all Farmall models converted to 12 volts about the same time. I cannot imagine the Cub being changed to 12 volts and the 140 remaining at 6 volts. The opposite of that is more plausible.
