Team Fitzgerald Thank you for the step by step instructional video. I now have done the 12 volt conversion upgrade on 4 Farmall H tractors a 48 Cub and a 55 300. Steiner also sells excellent wire harnesses. Thanks again

Very clear instructions, excellent lighting and video angles, good even voice with appropriate emphasis when needed. A great how to video!

I liked everything about the conversion except those solderless connectors. I despise solderless connectors with a passion. In my experience, after age and time, one of the clampings lets loose and then there is an electrical gremlin to chase. Good video and thanks for sharing. Will be referring back to this in the future.

THANK YOU! This is exactly what I needed to see to finish my conversion!

Like the videos guys.I just got my first ever tractor.A 1958 Massey Ferguson 50.I know absolutely nothing about tractors,in fact,I'm not even sure how everything works on it.But I got 10 acres that really need a major facelift.Can't wait to watch more!

In the late 70's , early 80's my buddy's family farm were still using several H's to shuttle hay wagons....before lunch I was told to "filler up" .....well after lunch I fired her up......black smoke everywhere......yelling and cussing "SHUT HER DOWN!!?" suburb boy (me) had put diesel in the H. A memory that will be with me until I die.

thanks for the advise and good instructions I bought that same 12 volt kit for my h but it still didn't charge but I was using the original 6 volt amp gage didn't know I had to change that now ill get a new 12 volt gage and ill check the wiring again I wrote down the instructions thanks a lot for the video steiner has helped me out a lot on getting me the wright stuff for my older tractors and advise thanks again

Marty from "Mountain Men"! Good video, very informative.

Mr. Fitzgerald did a great job with this Video , I learned a lot about this conversion. I will be trying this on a 1951 Farmall H .

Great video. My first working tractor is a '42 Farmall H. Just requested a catalog online. Thank you! It gets -20 F up here at times in Upper Michigan in the winter, the 6 volt system just won't do....

Good video the M sounds better than new!!

Ive brought parts from you guys, very pleased and recommend you to anyone!

Thanks for the comment. I do think there was a slight miscommunication in the video on that wiring (negative vs positive). It was worded a little odd. Anyone can also follow the instructions linked in writing above and is sometimes handy to have in the shop with you:

Great directions. Thanks!

Very informative and clearly explained. Whole process shown and important things stressed. Liked very much.

Excellent video Steiner! Very well explained!

Really nice job thanks for the video. That Ford looks really nice as well!

Very good video

I love Steiner videos.

On this one, they left the 6 volt starter on. You can run a 6 volt starter on a 12 volt system. It may reduce the life of your starter somewhat, but many people just run them this way. You can also take your 6 volt starter into a shop to be redone or try to find a 12 volt starter you can use. Those will add to the expense of the conversion.

Today I learned why they call channel locks/cobra type pliers "water pump pliers" because of this type of adjustable fan belt pulley thing

good job

Looks good but the way the ignition switch wire is connected to the ammeter will not show the ignition draw. The only wire on the + terminal of the ammeter should come from the battery. All other wires should be connected to the - terminal.

Looks like a pretty good set-up, I'd like to ask tho, did Steiner say a # 10 wire from the alternator to the battery? She started nice and quick, two thumbs up!

If I have an H with the distributor that’s horizontal, can I still use the 12 volt internally resisted coil and not the barrel one they mentioned in the video? Shouldn’t it still work fine? Not a magneto tractor. Thanks for the help!

So I'm guessing this conversion would work the same for an H with a magneto, MINUS the wiring back to the ignition switch, coil and distributor??

Awesome video, I just bought my first tractor last Saturday, its a Farmall Super C. I'm wanting to convert my Super C to 12v. My question is will I need to change my points on the disturber. Also I have another question that not electrical related, my tractor will still free roll if I put it into gear not started, when I bought it the brake assembly on the right hand side are disassembled I'm not sure if this is causing the tractor to not engage in gear or if something in the transmission is missing.

Great video and all my tractors have been converted from 6 to 12volt. But... you can’t call it a restoration because if that’s what you were intending to do you’d bring the factory 6volt system back to perfect running condition. This could be termed a resto-mod.

I just bought one for a farmall 100 and it says to run 12 ga wire to the POSITIVE side of the amp gauge why is mine different? thanks!!!

does there need to be a diode inline anywhere to prevent the battery from discharging when the tractor is shut of?

Do you have a video like this one for a Massey Harris '30, or '44 , age 1948 - 1953?

i have the smallest of the farmall tractors, a 1948 farmall cub, and yes its 6 volts. i think that on a cub, the 6 volt system is adequate in all but the coldest of temperatures, and yest i do use my tractor in all conditions. i plow snow with it in the winter, and mow my 2 acres of lawn in the summer. i wanted a tractor that was fairly in-expensive, reliable, has good parts availability, is economical on fuel, will hold its value, something that i can work on myself, and something that is compact enough to not take up my entire barn/garage but heavy enough to do some serious work as a small chore tractor. the cub is all of these things and is an ideal machine to have around the yard if cheapie disposeable lawn tractors are not your thing. as much as i can put up with the 6 volt system, do you have 12v conversions for the cub? part of me wants to keep it original and as i type this, everything works as it should. however, a 12v system certainly would give it some extra zing on really cold days.

Great video!! I noticed at 11:10 you said the positive of the battery goes to the ground. Is this correct?

Do you need to swap from a 6v starter to a 12v starter in order to do the conversion?

I converted mine back to 6 volt.

Wouldn’t you burn the 6 volt points on a 12 volt system?

I have a converted 46 H to 12 volts with magneto. It has solenoid. Without me looking at wiring, is the conversion the same as this video shows?

I have a ih 300 utility. It's a mess with the distributor I need major advise on how to re install it in TIME

I have an h and I was wondering about how to wire up a new 12 volt light switch and the lights. I have 2 new whole light assemblies that as installed but I just do not know how to wire the switch to the lights and whatever else. If anyone could explain or link me to help it would be appreciated

how would you do this if it was a farmall M

where did you get the starter and how do you convert to 12 volt starter?

Will this kit work for a m

Can the original light switch be used on my W4 for this conversion ?

What about a magneto setup?

Is this the same setup on a magneto ignition h?

Are you able to explain further why you didn't use the ballast resister, was it because the alternator has an internal resister? mine has the 70 ohm ballast resister before the coil? just a little confused can you please help clarify? plus i have two wire i need to rev it up to have the alternator charge and i my alternator has an internal resister? very confused thanks carlo

can someone give me a detailed list of what I need to convert a farmall 350 from 6 to 12.

Do you have to put a new starter on or can you use the old 6v one?

hello sir, does ur tractor has the Charging warning lights ? im having trouble in wiring the charging lights ... it wont goes away after the engine has started ... so can u please show me how to wiring the charging light or ignition warning lights .... thank you in advance.

do you sell original looking farmall/IH cable restrains ?

You can restore your tractor using steiner for 2.8 million dollars too

Bad video. Shows nothing!
