Recently I have been experiencing no voltage out to charge my battery. I have since tried taking the generator apart, cleaning and inspecting it, checking continuity on the field coils, and brushes, the brushes were a little glazed so I lightly sanded them with emery cloth and cleaned the armature end (which was dull gray) with 0000 steel wool to bring back the bright copper finish where the brushes ride. I then re-installed it and polarized the generator by touching a jumper from battery positive to "F" terminal on generator but still no voltage to battery. I am also running an electronic regulator. Its mounted on a 48/66 Pan Shovel. |
