Default Plane power 60 amp

Had my stator replaced today- kmorris is correct- unipoint mfg ND design copy, I'll measure my failed stator and report back. Data point- 286 hrs, no blast cooling tube. I'll probably add one now,

Who fixed it, Danny? I'd like to possibly give them more business. It's hard to find people who want to work on it when its got the words PLANE Power on the side!

Steve- local shop to me. J&J Starter in Baker, Louisiana. Jerry the owner had no problem doing the work when he understood it was experimental. It's a common Nippon Denso design- any quality shop should have no trouble repairing it. He replaced the stator and regulator assembly.

Looking forward to the dimensions !! Thanks

What is the indicator you have that the root cause was temperature? It was the stator that failed, right? Were the connector wires intact but shorted within the windings?

I, too experienced a failed regulator and stator coil within 75 hours. PP was excellent at replacing parts/replacing the alternator under warranty.

It would be a great service to the community if we had replacement parts identified by mfr # so that these could be repaired in the field. It was a pain to ship my alternator internationally when their was possibility of local repair.

I also had a failed 35A alternator after 300 hrs on my RV-9A, but I replaced it locally. For a part that frequently fails, it sure makes sense to have a local repair source.

I guess what I'm saying is that PP should publish the common repair part numbers so that we can perform local repairs.... the alternators are, after all, for airplanes that we've managed to build ourselves. We should be able to repair them ourselves. Even putting the repair parts on Aircraft Spruce would be a huge benefit. Spruce holds stock all over the world.

Default Unipoint Alternators

All -
I did a quick web search and found Unipoint's web site. They have a significant number of catalogs available for download, and they have cross-reference numbers as well as some dimensions. A quick perusal of their alternator catalog shows a lot if them that look very similar to the 70amp PP on my airplane. Should be very helpful. Unipoint.com should get you there.

Addendum - by comparing images and searching auto parts, I found a likely replacement for my 70A at Advance Auto Parts - reman, not new, for $129.99 with a limited lifetime replacement. Of course, this has not been verified by looking at one in the flesh, so to speak, but it looks promising.

Sam,
Part number? My PP just crapped out last Sunday. Pulled it today. This is the second failure in 450 hours. Not impressed. I'm going to see about a local repair, but I would like to get a Wiki of part numbers, etc. going for the PP. Doug?

BTW, it's http://www.unipoint.com.tw/ Need the .tw or you get a technology company

I got a 50 Amp ND alternator set up for non-standard rotation (to help cooling). It was $40 from amazon or autozone. It's cheap enough that you can keep a spare in your baggage area. However, you can usually pick one up at a local auto parts store 7 days a week. Far greater utility in my mind than the PP. Sure, it may only last several hundred hours, but at $40 it could be replaced preventatively at 500 hours.

I can't believe that PP would use a cheap knock-off alternator and charge $500 for it.

Default Advance Auto Parts

Mike -
With the proviso that I have not had my hands on one, check part # 13326A. Acura Integra 1992 1.6l - the graphic appears to be identical to my 70A PP. pricing for my zip code is $129.99 with a $26 core charge. Lifetime limited warranty.
