OKAY, we're getting there. Often times fellas crank the 3rd Brush screw up to 'HIGH' when charging issues arise but that can cause overcharging. Mark its position before turning it down to 'LOW'. I strongly suggest you take the battery, generator, and cutout to a knowledgeable starter/alternator shop for proper inspection. It (battery) is connected as a positive ground system, right? Just to get a clear picture of what we’re dealing with, the pictures here show an original Induction/Loop style AMMETER on an early 8N. Note the Large Yellow #12ga wire feeding from the Ballast Resistor center post thru the ‘loop’ on the gauge, then to the Voltage Regulator BAT terminal. Also shown is an original 9N-10000-C generator with the Belt Tensioning Kit Assembly installed. The kits were available for the 9N-C generators but when the 2N-10000 generator was released, it was now part of the unit having a bracket bolted on the barrel, no need for the band –see picture. The band kit will not fit the early 9N-A nor 9N-B generators as their barrels have a smaller diameter. I’m not saying you must have this original tensioning bracket/kit, many farmers designed their own, but without some sort of tensioning device, the generator will not hold the proper belt tension simply with the generator mounting/pivot bolt. So, you say you do have a tensioning bracket so we can eliminate that from the equation.
