Since I'm temporarily grounded waiting for new alternator parts, figured I'd satisfy my curiosity with a poll on alternator reliability during the initial 250 hours.
Poll caveats/criteria:
1. This is created with the recognition that quality of installation matters, regardless of alternator type.
2. I know some alternators wait until hour 251 to fail, but I had to make the cutoff somewhere. 250 seemed reasonable. I think most would agree that fewer than 250 hours represents premature failure.
3. Depending on hours (especially if you have flown less than 250 hours on the alternator and have not had a failure), you may not be able to reply to the poll.
4. I don't know how make the poll work for multiple installations/multiple aircraft, thus the poll only applies to current aircraft. Please use the poll to document the reliability of your initial alternator installation (unless you did not have it on long enough for it to fail or to otherwise reach the 250 hour mark before replacing it).
5. First hand experience only.
