I change out my alternator every 400 hours. I have an overhauled alternator on the shelf to do this. Remove the old one, put the overhauled one on. I always use Jimmy and Debbie at Modified Aircraft Accessories to to my work. And I have always been pleased, indeed.

This time I put the overhauled alternator on the plane, and it wouldn't put out any juice at all. Nothing. Nothing we did would make it work. Jimmy had overhauled it three years ago, and it had been sitting on my shelf ever since. So I sent it back to Jimmy with a report of what happened. I did not ask for any warranty, as I thought after three years on the shelf the problem should be mine.

Jimmy ran the alternator for three hours at full power. He started the morning he got the unit back from me. He called me and told me the alternator was running fine. I asked him to take it apart and look at it, which he did. When he put it back together, it didn't work. After taking it apart several times, he concluded that he had installed a faulty new brush at overhaul. So he fixed it and shipped it back.

Jimmy and Debbie refused my offer of payment, and even refused payment for shipping. This was a failure that no one could have foreseen, but after three years--and without asking-- he stood by his work.

Anyone who needs an alternator overhauled or worked on by a reputable company should strongly consider Modified Aircraft Accessories--which is just Jimmy and Debbie in Brooks, Kentucky outside of Louisville.

While I am not happy that the brush manufacturer supplied Jimmy with a brush which had a full failure mode, I am most happy indeed with the wonderful and personal service. Couldn't ask more.
