Reviews
Ive had pretty good luck with this alternator. I just replaced it at 1000 hours just for my own piece of mind. The 70A runs at a slower RPM than the 60A, and works well on my IO-540. If I were doing it all over again though Id consider doing an externally regulated alternator with an adjustable regulator. Mine runs between 13.9 and 14.0V right now, and it would be nice to tweak that to 14.2.
