Tester measurements on the alternator output indicate no charging.
The alternator was dismantled showing that all components were OK.
The mechanic said that "he polarized the alternator" and subsequent bench measurements showed that the alternator was performing very well, charging without problems.
Anybody has an idea about what could have happened in the engine for depolarizing the alternator?
Where to look in order to avoid another depolarization?

Thanks in advance!
Did your boat sit unused for a long time prior to this alternator problem starting?
