Several things can and do go wrong. The two sections of this regulator (not all)are very much seperated from one another. The component you are probably pushing to make it charge is the cutout relay. It has two windings on it, a pull in winding of thin wire, and a hold in winding of fat wire. The pull in winding assesses generator output, and when it is higher than battery voltage, it pulls on the flipper closing the contacts and connecting the gen to battery. All current flows through the fat winding, causing additional closing power on the contacts. (hold in winding) If the gen slows down, its output is lower than the battery. The current reverses through the hold in winding and the magnetic force is in opposition to the pull in winding, and the points open, preventing discharging when going slow, or shut off. The other unit is field control. It is always "on" when the tractor is shut off, the contacts are closed grounding the field. The field gets its volts on these units from the armature brush connected to the Armature terminal, and thus are dead when the cutout is open) As the gen turns, the field poles supply enough magnetism to pull in the cutout. This also makes enough voltage to ad to the field current, through the contacts to ground. As good charging voltage is reached, the field control contacts begin to chatter clipping the field voltage to limit the charging. When the field contacts are momentarily open, a resistor is then connected to ground allowing enough charging to keep the battery up. Though almost always chattering to controll charge rate, they can open all the way and let the resistor take care of the charge rate. Comon issues are poor contact VR ground, poor generator ground, point cleanliness, moisture, broken wires, or bad external wires. Many Vrs are now made off shore, and are not reliable. I hope this helps. Jim

Today's Featured Article - Grain Threshing in the Early 40's - by Jerry D. Coleman. How many of you can sit there and say that you have plowed with a mule? Well I would say not many, but maybe a few. This story is about the day my Grandfather Brown (true name) decided along with my parents to purchase a new Ford tractor. It wasn't really new except to us. The year was about 1967 and my father found a good used Ford 601 tractor to use on the farm instead of "Bob", our old mule. Now my grandfather had had this mule since the mid 40's and he was getting some age on him. S
