with Plane Power, B&C alternators
Alternatively consider the Denso 100211-1680 alternator,
available brand new from many sources for about $200. Its
rated at 42A and weighs 6lbs. This is the same alternator
that Niagara Airparts used to sell, and it has built-in OV
protection. I have had one for 700+ hours and its been
rock-solid reliable. The most appealing thing about this
alternator is the availability of it as a rebuilt unit at a local
auto parts store. Once I had a friend I was flying with have
an alternator crap out on a trip, and we were able to get
him going again after a short hop to the a auto parts store
after landing at the nearest airport along our route. His
alternator was one of Van's old 35A units.
I have a source for these new alternators, email me off-line
if interested.Niagara will still sell the brackets for $75.00.

Bob, I have a Niagara unit and I concur they are excellent.
There is nothing like new OEM ND's. If you can get a new
genuine 100211-1680 for $200, that is a good deal.
I agree that availability at auto part stores is a cool thing, but
I found car/auto part stores don't stock this exact unit. The
reason is the main application is a Japanese folklift. There
may be an equivalent. However you can get parts and
worked on at auto electric repair shops.
A fellow RV'er with a Niagara 100211-1680 also got rock
solid service with his. He did have an issue at over 800
hours with worn brushes (to be expected). Plane power
recommends I think looking at them at 700 hours and I am
sure B&C wear out brushes.
I recommend everyone regardless of alternator brand check
their brushes in the first 300-500 hours and than every 100
hours or so after. They are cheap and easy to replace. It's
good preventative maintenance. You might as well just
replace them. Interesting NOTE the higher you fly or the
dryer climates the faster brushes wear. There's less moisture
at altitude and brushes wear faster. However below 8,000 feet
there is not much difference. I'm talking about flying +10k ft
most of the time. If you fly high / dry than check the brushes
more often is my advice.
