I have an 44 SC that I am almost done restoring. I have a generator and regulator that I got with it but, I don"t know which wires go where from the gen to the reg. Can someone tell me which wire goes where and then from the amp gauge? Also I recall that the generators can be "adjusted" by moving the brushes to put out up to 12 volt. Any ideas how I do this? Thanks, Fredct.

Fredct,

Regarding the wires coming out of the generator. Connect the armature wire of the generator to the "A" terminal, (also sometimes marked GEN or ARM), on the voltage regulator. The armature wire should be the larger of the two, but you may need to follow the wires to where they lead inside the generator to see which is the armature and which is the field. Connect the field side of the generator to the "F" terminal on the voltage regulator. The "BAT" terminal connects to the load side of the ammeter, the same side that the headlight switch is wired to. The other side of the ammeter goes to the starter switch, the same side of the switch that the battery is connected to, while the other side of the starter switch goes to the starter motor. Hope this helps.

Dan

If I remember correctly moving the third brush in a generator that has adjustable brushes only affects the amperage the generator puts out, I don't believe it increases the voltage.

On a third brush genny that uses a cutout relay, adjusting the 3rd brush does indeed increse the voltage.. that's why the current output increases.

Now.. some people retrofit a 3rd brush genny with a regulator, then they usually turn the 3rd brush all the way up and let the regulator do it's thing with the vibrating contact.. or else they convert the genny, and remove the third brush and let the regulator handle field current.
