This should look pretty even and smooth. Maybe a little darkened from brush carbon. All of the sections/bars should look the same. Try pressing down on the brushes. If they are even with the top of the holders, they are due for replacement. You might want to just rebuild the generator you have. Take it to an automotive electrical shop and have them check it out. If the armature is good, they can turn the armature and replace the brushes. Or, if you have a lathe, you can do it yourself. -- Russ Wolfe '66 FB MT '71 FB AT '65 Bug (not running) russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
