Hi. I have a 1955 Johnson 25 HP electric start, and the starter is dead. It turned the engine over a few times for my dad, then stopped working. It won't turn even with a good battery directly connected to the starter. I've pulled the starter from the engine, and am trying to figure out what is wrong with it now. It was full of copper dust from the wear of the copper brushes and gunk, so I've cleaned all that out. The copper brushes look fine and have a lot of life in them, but the insulators between the commutator segments is flush with the segments. Does anyone have any tips on testing the commutator? From what I have seen, there should be continuity between all the commutator segments, but not the central shaft. My dad disagrees, and says there should only be continuity between commutator pairs, not all segments. Any other advice on reconditioning a starter? How does one test the windings?
Thanks.
Thanks.
