FORD TRACTOR 12 VOLT CONVERSION INFO

For all N-Series Tractors and others.

Just Scroll Down and click on the link to the specific wiring diagrams you are looking for.

This page links directly to all of my 6 volt and 12 volt wiring diagrams. There are specific diagrams for the Ford-Ferguson 9N, 2N, Ford 8N, 53 Jubilee, and Ford 601,801,901 tractors. The information on this site is also useful for many other 12 volt conversions. I will add wiring diagrams for other vehicles as time permits, or as people send me diagrams (hint). Sorry, I cannot publish any material that may be copyrighted without permission of the original author or copyright holder.

This is my most popular web page, so it is frequently updated, based on feedback and questions I get. Hopefully, that means the information is getting clearer and easier to understand. I believe this format, with links to each set of diagrams, provides access to the correct diagram much faster.

My tractor collection and research skipped everything built from 1955 to 1965. Sorry about that. These diagrams are an attempt to provide something for the tractors built from 1957 to 1962.

This is a direct link to more free wiring diagrams published on the ntractorclub web site. Wait for it.... This links to a large PDF file with all of the diagrams in one file. Yes, it is worth the wait. Please, look around while you are on the N Tractor Club web site. The How-To's and Manuals sections are loaded with great information. I enjoy responding to messages about tractors, but you will get faster answers, from more people, if you search the archives, and ask questions on the N Tractor Club forums. I'm not on-line 24-7 but some of those guys seem to be. There is also a very remote possibility that I may not be 100% correct, 100% of the time, GRIN.

This ain't the same as having surgery on your body, but getting a second opinion is still a good idea.

As previously mentioned, all of my conversion diagrams have been designed to stay as close to the original wiring as possible.

For many years there was one serious error in many of the "store-bought" tractor conversions. Those conversions were wired so the ammeter no longer measured current flow in and out of the battery! They were connecting the ammeter so it could only measure alternator output. All of the better conversion kits and diagrams should have corrected this error by now.

ARE YOU SURE YOU WANT TO CONVERT?

There are some good reasons to convert your tractor to 12 volts, but there are at least as many reasons for keeping the original 6 volt system. If you have already decided that a 12 volt conversion is the right decision for your tractor, and are positive that you are capable of doing the work properly yourself, please skip this link.

The original 6 volt system is usually less complicated, more durable, and cheaper to maintain than any 12 volt conversion. If your are the least bit unsure of your reasons for wanting to go with a 12 volt system, or you believe a 12-volt conversion kit will solve all your tractor problems, please review the additional information I have provided on the 6 volt vs 12 volt decision HERE.

The diagrams show the BEST way that I have found to convert your 6 Volt, Positive Ground, N-Series Tractor to 12 Volts, Negative Ground. If you are interested in some less-common conversions, I have provided examples of some Other Conversions.>
