Plane-Power vs B&C (2019) also: Parts info wanted

[Raymo]

Another data point:

My PP 60 amp internally regulated alternator failed after 340 hrs (purchased in 2016). They replaced it under warranty and it would have been very easy to put the new one on my plane but it now has the B&C L40 with external regulator in the cabin.

On another note: Anyone interested in purchasing my new PP alternator?

Follow the link below. Look for the small photo of the alternator and tap on it to get multiple views of the alternator. You will see how the mounting system is set up. It has a bracket coming off both the front and the rear half of the casing. The rear leg of the mount also has a sliding bushing which allows it to adapt to mounts of varying lengths. Pay attention to the rearview and you'll see up near the top where the two terminals studs for the external voltage regulator are.

I just stumbled across this article. For those with standard flooded acid batteries don't bother reading it it doesn't really pertain to you. However if you have an AGM battery or a lithium battery you might want to read the section titled internal Regulators versus external regulators.

https://www.westmarine.com/WestAdvis...-an-Alternator

Those of you with more cutting-edge technology batteries might want to consider using a voltage regulator that can measure the temperature of a remotely mounted (rear) battery. I haven't done much research on this. However I've stumbled across one or two marine and Automotive voltage Regulators that have this capability.

Just food for thought and worth exactly what you paid for it.

I have been looking at the Chrysler alternator, online, for some time. Specifications list the weight at 12 pounds? Does the PlanePower pulley fit the shaft diameter? Is the housing small enough to fit in the space?

Smart move, You won't regret it.

Yes the PlanePower pulley will fit the shaft on the Chrysler alternator. The Chrysler alternator is the same physical size as the 70 amp Nippondenso that the original poster reported having installed on his aircraft. That said, I have no idea if you could get it to fit on an RV 3 or an RV 4 due to their extremely tight cowls. ( most likely not)

Still another option would be, purchase a 70 amp Nippondenso alternator for a 1992 Toyota Camry. That was the last year that had the round style electrical connector on the back. For about $15 you can purchase the brushes, brush holder and terminal block for the Chrysler alternator and retrofit them into that Camry alternator. The terminal block replaces the internal voltage regulator. That is a totally bolt-on modification other than the slight modification you'll have to do to the sheet steel back cover on the Camry alternator. You have to cut open a rectangular hole in that cover for the two electrical terminals on the terminal block. Contact me via private message, with your email address. I can email you photographs of that mod.

Do you know if that 12 pound weight that you quoted is the actual weight of the alternator or shipping weight ? I would suggest you also check the weight of that 1992 Camry alternator. There might be a weight advantage in simply converting that one. As a general rule, the weight of an alternator will go up when they increase its power output. That is due to the fact that they have to increase the number of windings in both the rotor and the stator. Those extra windings add weight.

Curious where you sourced your spare Plane Power modified regulator?

The shipping weight listed is 14 pounds. I figured that more copper and a large housing equals more weight. Swapping parts sounds like an attractive choice.

Dan, the spare regulator I got from Aircraft Spruce, for my Plane-Power. You may want to verify that this one is for the 60A experimental alternator, but I think it is, based on the timeframe that I ordered it. I bought one for my 70A long ago. I purchased one of these on 8/24/16:

11-1043 HARTZELL PLANE-POWER REGULATOR BRUSH ASSY 07-17968
$79.85

It comes complete with a new regulator, brushes, and the pin side of the connector. (Not the plug side of the connector that the wire harness is attached to.)

I carried it with me and when I had my 60A rebuilt recently, they replaced it with my spare.
