  • 6volt
  • I have a 8N serial number 284004
    Did all 8n come from factory as 6 volt?
    If mine is 12 volt then converted in distant past?
    If 12 volt can I assume Neg ground?
    Any sure fire way to tell Generator from Alt? I don't see a
    voltage regulator

  • Re: 6volt
  • Google car generator or Alternator.
    Many Alternators have VR built in...

  • HiYa Dud-
    Sounds like you are new to the wonderful world of Ford Tractors. First, all Ford vehicles were 6-VOLT/POSITIVE GROUND up until the late '50's, not just tractors. Diesels first introduced 12-volt/negative ground systems. Over the years, many 6-V vehicles have been switched over to 12-V including N Tractors. Serial numbers don't necessarily mean much, meaning don't count on them being correct nor that the entire tractor is correct. Engines were often swapped out when one blew. What is important to know about your tractor is 1) does it have a front mount distributor or a side mount, 2) is it 6V/POS GRN or a 12V switchover job, and 3) does it have a 3-speed transmission or a 4-speed. Be aware that just because you have a 12V battery on your tractor does NOT mean it has been changed over correctly to a 12V system. Likewise, if you have a 6V battery on your tractor, do not assume it is correctly wired as a 6V/POS GRN system. Add to the fact that many 12-volt jobs are wired incorrectly from the get go. Most poor/incorrect/bad wiring jobs are done by people who don't have a clue on how to correctly wire them whether 6V or 12V. Fortunately, a frequent member here JMOR put together an excellent document on how to wire these old N's correctly. Note the RED MENU bar at the top of our homepage, See the forum "HOW-TO's"? there is a ton of D-I-Y projects and technical documents there for free download to use as guides. Under the ELECTRICAL subcategory is "WIRING PICTOGRAMS BY JMOR". It contains every possible CORRECT way to wire these old N's, 6V or 12V. Find your set up, and start with that. Do not assume anything. If you don't how tell a generator from an alternator, you better learn fast and/or get someone who does know to help. Just tossing a new battery on without knowing what you are dealing with including whether the rest of the wiring is correct, is foolish. It is also advisable to get Bruce's 75 tips as a guide too and invest in the essential Operator/Owner manuals as well. There is a quick LINK to the HOW-TO's forum at the bottom here...

  • Tim, Is your email working? I've sent you at least two emails concerning the generator tension bracket and no response. AL CT

  • Re: 6volt
  • It came from the factory 6v, positive ground.

    Open the hood on your car. See the alternator? Does it look like the one on the tractor?

    Or Google 8N generator and see a picture.

    Why assume anything? Just look at the battery cables. If the cable on the negative battery post goes to the tractor chassis, it's negative ground.

  • Re: 6volt
  • Thanks. The battery was pulled out and no one paid attention to battery cables. The battery
    was 12 volt but sitting next to my favorite 6 volt car. A VW which is why I started wondering the battery is a group 26R?

  • Re: 6volt
  • On most 12volt batteries the positive post is larger than the negative post. Don't assume anything. Lots of people wire these old tractors and don't know what they are doing. Seek good sound advice. Like you get from us old farts here :-)

  • JMOR's wiring diagrams are good to know about. The first three diagrams show generators. The fourth shows an alternator. More below but those will give you the information you need to determine which you have. If you have an alternator install the battery with a negative ground. Generator most likely would be a positive ground.

  • Re: 6volt
  • Check out tip # 39. You have a 60+ year old tractor; the manuals are essential.

    Re the battery, the original 6V battery is Group Size 1 - 9-1/8 (L) x 7-1/8 (W) x 9-3/8 (H).

    12V Group 25 & Group 35 batteries are just slightly smaller at 9-1/16 x
    6-7/8 x 8-7/8.

  • Thanks to everyone for your help. It looks like an alternator! I have ordered the suggested books. I sure never knew about the 6 volt fords but I did know the Model A and VW
