| Lazy Generator | |

| Well, my PMR generator had gotten weaker and weaker , down to | |
| about 1.5 volts , and It would just barely operate anything. I | |
| took off the brush end frame , and after an inspection, cleaned | |
| the commutator and brushes , paying special attention to the | |
| grooves between the commutator segments . There was a big | |
| buildup of crud in those grooves , so I think that was the | |
| problem . Anyway , it seems to be back up to operating | |
| potential. I haven't tested it with a volt meter, but it really | |
| does power my electrical accessories like it should. If it works | |
| with the PMR , I think a good cleaning might possibly rejuvenate | |
| any weak , small generator that has brushes . | |

| Any pics of the goop between the pads? Wondering if it was a | |
| mixture of oil and worn graphite from the brushes. Could maybe | |
| end up grounding out any power generated back into the coil | |
| before it gets to your line | |

| I don't have any pictures, but that is was what it was , Oil | |
| and graphite paste . The tip of an Exacto blade scraped it right | |
| out . Since I like to lubricate things, I imagine over oiling is | |
| the culprit . | |

| I give mine an occasional spray of contact cleaner. | |
