    11 Degrees & lotsa wind cancelled gen/alt change-over project for a spell

    I mentioned changing my 720 over to an alternator. Welllllllll.......someone here commented that the gen system always seemed to be a good one. I agree. My '61 car is still using its original gen/voltage regulator. 1962 race car even had one on until about 5years ago, wound it up to 7200 way more times than can be counted.......... Wifes '63 has the first of across the marque alternators/regulators. Couple years later they eliminated the external regulators.

    With the built in regulators, should be an easy swap........not so. The positive grnd is the worm in the woodwork here. Has complicated coil & amp/volt meter......I dont know which the JD has.

    Anyway, I took the gen/reg to the local shop to have it tested.........would you believe they gathered around & laughed at it???? Then they had to call the testing machine mfgr to find out how to attach it to the machine & how to hook things up for the testing. Result was......no test. They did find me a new regulator, $21.00.

    Isnt there a 'field' test for gens??? Hook a hot wire to the ???post, ground the case & a good one should run like a motor does??? Donnas older tiller uses the gen to start the engine. Used to be std practice on Simplicity mower/garden tractors........

    Your tractor definitely looks to be in real good shape.


    I will be going forward with installing a one-wire alternator along with a new wiring harness and gauges. Don't have much choice on the gauges. They're all busted and I can't trust them. After all the work I'm doing, I'm not going to not have reliable and trustworthy wiring and gauges.

    Looks good. That's the way to go if you aren't concerned with keeping it original. I was working on my generator today till I got called for grandkid watching detail. Brushes looked good except that one of them wasn't hooked up. Cleaned up the armature and replaced the front bearing. Will paint and reassemble tomorrow. Just hope my gen rebuilding skills from the 60s still work. Fixed a lot of tourists generator light problems back then coming down Highway 30 stopping in my home town. It was beer money and not much work.

    11 degrees... About what it was here a couple hours after the sun came up.. -2 when I got up at 5:30 to feed the dogs. Just good football weather....

    football

    My 11 was well into the afternoon sunshine....our local weather folks informed us that it was colder here than in Alaska.........???!!!

    I like original, one reason I am going back to gen........and the mentioned glitchs that need to be over come. Not looking to have to take the dash panel out to rewire whatever gets funky after the alt. is in service. My gen. has its original paint.......... I will not live long enuff to do a restoration of this tractor. Next guy maybe.......her attitude is that it is a never sell.

    "Football weather"...... Seems many southern stadiums have roofs...........where as many northern ones dont. There is a potential squabble brewing over the Super Bowl location temp. I personally think the game should not be played when/where the temp is below freezing. There are plenty of indoor stadiums for winter use.

    if your local shop laughed and had to call someone on how to test a generator i may think about using a different shop haha

    when i test mine, all i do is put it in the vise, spin it with an impact and meter the posts to each other and to ground and see if i have anything, then test the regulator. I dont have one in front of me right now so i cant tell you which ones you should have voltage on, but most regulators can be taken apart and see if anything is burnt up.

    - sometimes all they need is energized - basically putting 12 volts on the posts for a second and that sets the magnetic fields, i have to do that on my generator welder sometimes when it sets for a long time, and its actually a generator out of a B-17, ill have to take some pictures of it sometime.

    swapping to an alternator is okay, i have a a 50 that was switched over, but i havent really ever seen the point, unless you wanted to upgrade to electronic ignition, but other than that, these tractors ran for years with them and they are just as easy to work on as buying a new gm alternator, but as they say, whatever floats your boat.

    Gen/reg

    As mentioned, Donnas old Simplicity tiller uses the gen as a starter. So that has to be a test possibility as I dont think I have a meter set up for the testing mentioned above.

    I am familiar with the need to polarize the regulator. This tractor does sit for extended periods, which may account for intermittent gen operation. Does anyone remember just which posts on the reg need to have what done???

    I worked briefly on it yesterday, but my Ford tractor lost its battery & that was a bit of a priority, was an easy fix too. I need to finish taping the smaller wires to the new battery cable & mount the whole assembly to the rear of the foot platform just below where it goes into the battery box/seat.

    Any input on polarizing the new regulator???

    My old IH with a 12 volt generator would have a voltage regulator fail about once a year. Not saying that's your issue, but might be worth checking on.

    Polarizing gen after storage

    Did you read the link information above about the polarizing???

    Reading between the lines has kinda revealed my problem, tractor sitting for long periods of time. Since polarizing is so simple, might pay to do it if your start ups are more than 2-3months apart.

    My '61 car sits for 6months at a time but always works perfectly on start up..........makes my comment not so valid....???
