Denso can't afford substandard parts quality to save a few pennies by offshoring components. I'd guess that any plant they set up outside Japan would be supervised by Japanese and employ the same process control and QC as is used in Japan.

You don't risk a 50 year reputation as the top OEM auto supplier of electrical components in the world. We've seen how that turned out for one supplier here...

I have a friend who works at Denso in Japan, I'll ask and see what he can find out.

Default Second PP 60 amp alternator failure on RV-10

First one that came with the kit failed at 191 hrs. Voltage down to 12.8 from 14.2 VDC. Whining over intercom below 1200 rpm. The STATOR was not secured properly with epoxy coating, hot glue or sealant. No star washers were used under screws. This caused the the stator wires to break down deep, which are unrepairable. Replaced stator for $80. Keeping this alternator for a spare. Prop was balanced (PP liked to blame all of their broken stator wires on vibration or heat), no #1 exhaust heat shield and no cooling blast tube used since new. No problem with rectifier, regulator, oval 3-pin connector or brushes. No signs of overheating.

Second one has now failed at 45 hrs. Voltage down from 14.2 to 13.6 VDC. I will let you know what I find on that one. Time for a change and I won’t be spending $600-$800 anymore on $100-$150 alternators. 3 pin oval connector replaced as part of my troubleshooting. No change. Replaced 9 year old PC925L just in case. No change. Replaced 3 yr old, 3rd PC680 aux battery. No change.

I hope you are holding Hartzell's feet to the fire for help on that early hour failure. Like an overnight shipment, teardown report, and labor to install the new one. Levi ( I think is his name) came on here and helped us at one time understand their improvements.

Do you know what failed? Did you use the new connector, or the old one?

Default 2nd PP voltage decreasing

See my edit above. I will keep you guys informed.

There is nothing special about these overpriced alternators with their “proprietary” overvoltage protection. How many overvoltage occurrences have you heard of in automobiles or aircraft. It’s just a way to charge $500 more to us “rich” airboat owners.

I am not calling Hartzell. It is poor business practices and customer service to sell an alternator, then not provide repair parts or repair services at a minimum. Instead, they just recommend buying a new one. I trust my local guy with 50 years of experience.

My Duralast 14184 finally quit last month after 24 years and 1000 hours of faithful service.

If you still own the 1978 Honda Civic you can go get a free replacement alternator.......
