Assuming a mechanical voltage regulator, yes. There are (two or three relays under the cover) one will be a cutout relay with heavy wire around it. and two more one with both fine and heavy and one with fine only. If only 2, there will be one with heavy and one with fine wire. Adjust the tension on the relay with fine wire only. It will be the voltage control it works by vibrating the contacts causing the field to get pulsing DC. The timing and on state of the pulses control the amount of field current being made, and thus the output voltage. Id the spring holding the contacts closed is just a bit too tight, the generator over charges. The amount of change to adjust is very small. Some have a screw that is used, and some just have a tab that anchors the spring that is bent to adjust. Make sure the battery is fully charged prior to adjustment. This allows an accurate voltage setting. The cover will also affect the output as the cover changes the magnetism in the towers unpredictably. so before assuming success put the cover on and recheck. I have described the adjustment as though it was simple. It is delicate, and can be complex. Finding a Motors Manual from the late 50s will help understand what is going on. Reading is your friend. Libraries have copies and photo copying them is a real possible solution. Jim

Today's Featured Article - Third Brush Generators - by Chris Pratt. While I love straightening sheet metal, cleaning, and painting old tractors, I use every excuse to avoid working on the on the electrics. I find the whole process sheer mystery. I have picked up and attempted to read every auto and farm electrics book with no improvement in the situation. They all seem to start with a chapter entitled "Theory of Electricity". After a few paragraphs I usually close the book and go back to banging out dents. A good friend and I were recently discussing our tractor electrical systems when he stated "I figure it all comes back to applying Ohms Law". At this point
