Melvin said: (quoted from post at 21:24:55 05/07/09) Thanks for the information and tips on troubleshooting my charging system. I was obviously under a misconception of exactly how this thing is designed to work. The weather finally cleared enough to get back to troubleshooting and I found that by jumpering the voltage regulator "F" terminal to ground, it suddenly starts working. According to what you guys are saying, this would indicate a bad voltage regulator. My question is, will any generic two pole regulator designed for a "Class A" charging system (NAPA, AutoZone, Advance, etc.) work here or must I order one specifically for a Farmall Model M Tractor? I want to be sure to maintain the proper charging voltage output.
Also, since the battery provides no excitation to the generator in a Class A charging system, does this mean the generator is "self excited" via residual magnetism? Is this the reason for "flashing" or "polarizing" the generator?
In all my years I've never had to work on a voltage regulator system so it's great to finally understand and appreciate how all of this works. Thanks for your help.
The BEST way to order regulators is to get the tag no. off the generator, if there is one. A couple of things that are VERY important about regulators for generators is that
They be the right one, period, if at all possible, because
Some are reversible polarity and some are not--I was told the difference is in the contacts material This deals mostly with the aftermarket In other words, if you get an otherwise correct regulator for the opposite ground polarity, the contacs won't last long
The regulator's job is to limit current from the generator to protect it, I.E if you put a regulator for a great big generator on a smaller generator, you can burn up the generator when the battery is low, because the "big" regulator will allow too much current
Also even Delco had some type A and B systems, so you certainly want that part correct.

Today's Featured Article - Usin Your Implements: Bucket Loader - by Curtis Von Fange. Introduction: Dad was raised during the depression years of the thirties. As a kid he worked part time on a farm in Kansas doing many of the manual chores. Some of the more successful farmers of that day had a new time saving device called a tractor. It increased the farm productivity and, in general, made life easier because more work could be done with this 'mechanical beast'. My dad dreamed that some day he would have his own tractor with every implement he could get. When he rea
