The generator is so designed that ther is no necessity for removing it for minor adjustments, as the brush holder or armature can be removed without removing the generator casing. the armature has a fifth brush adjustment for increasing or decreasing the flow of current to the battery.
The attachment of generator provides an easy method of adjusting the tension of the fan belt and is kept dry and free from possibility of oil entering the generator and affecting the armature or bushes.
To change the charging rate, remove the generator cover and loosen the the field brush holder lock screw (not too much!) shown at A in the picture. It can be identified easily, as it is the only brush held in a slot in the the brush holder ring. To increase the charge rate move the brush in the direction of rotation, a small wooden stick is best. Again a little is better than more. The output is shown on the ammeter. 10 amps in the winter or with long night driving, and can be cut to 6 amps or less for long daylight trips. If you make numerous short trips, with many stops, the rate may be set higher than 6 amps. Don't boil your battery, but don't let it run down either.
