I originally had a Plane Power 60 amp main alternator and their Fly Save alternator in my RV 10. I purchased both in late 2016, but the plane did not go operational until early 2018. Just past 400 hours, the main failed. That was the approximate number of hours (that has been talked about on the forum) when the PP alternator would fail. It did. I replaced that with a B and C alternator. Not long after that, the Fly Safe failed and had to be replaced, which was past the warranty period. So I just installed a new PP Fly Safe. I did not want to hassle installing another OV relay and the wiring required. My bad. With less than 200 hours and two years, the spider gear (shear part) failed on the new one. I returned it to Hartzell PP, along with my concerns about the failure and requested that the alternator be thoroughly inspected to ascertain if there was anything deeper that caused the this failure. After two weeks I called PP warranty and service department since I did not hear back from them. I was told the alternator had been inspected and the part replaced and it was being shipped back. When I got it back, all they did was drop a new spider shear part in and a quick bench test. The technician did not ever bother cleaning the mounting base of the remaining gasket material or some black unidentified rubber material. I plan to roll with this alternator until it fails again (and the warranty has expired). Then I will go with the B and C version of it. I have no faith in either the Plane Power product or their warranty service. After three separate failures with their product and the poor warranty service. I’m done.
Also, I purchased an accessory gear cover and gasket to have on hand. When the time comes and I need to pull that alternator again, I won’t be grounded for weeks. I can toss the cover on until I install a replacement.
