In Reply to: H Farmall charging system posted by Alan on May 24, 2004 at 20:37:03:

Is there one set of points, or 2 or three? If just one set under the cover, you got a cut-out wich works in conjunction with a four way light switch. The bottom 2 notches on light switch are for high and low charge. If there is multiple sets of points, then you got a regulator. It works independantly and does not need the use of the 4-way light switch, which is why these were equiped with 3-way light switches from factory. I got the cut out and four way switch on mine. I do know that when in the high charge setting, I have to have the engine reved up to put out enough juice to close the points in the cut out. Then it will show a charge on the ampe gauge. If you have a 4-way switch and cut-out, make sure you are not trying to overcharge the battery. Don't have to worry about that with regulator. Electrical system does have to be polarized at the generator. There is three terminals, and I can't remember wich 2 you breifly jump together to polarize. As long as you show a positive charge and not a negative charge it is right. One more thing, remember that the H was originally positive ground from factory. That means the postive post on tractor was hooked up grounded to tractor and the negative post to the power point. Not sure what year they changed from cut-out to regulator, but remeber this- most of these H's have been altered from there original electrical system one way or another. Check yours out. If you got it from somebody else, it is hard to tell what they tried to do.

Today's Featured Article - Farmall 460: That's My Girl - by LeAnn R. Ralph. How many sounds can you think of that are as familiar to you as your own breathing? What about the hum of your refrigerator? Or the thump of your clothes dryer? Maybe the engine of your car? You hear those sounds every day, and you don't think much about them, do you. I can think of a few common, ordinary sounds in my daily life, too. ... [Read Article]
