Lew,
Use a multi tester or a voltmeter to test the output of your gen. at
idle, it should read 12 volts, raise the engine speed and watch to see
if the voltage rise is steady or is sudden, if it is steady, ck to make
sure belt is ajusted properly, if it is, you may need check your
comutator brushes. If the rise is sudden you might have a bad
regulator, or just fried points. Fried points can be filed smooth with
a point file, but then you need to re-adjust the contacts.
As always this is JMO.
