Thank you Pat!

This RV builder has some very detailed info and pics on the inner workings of both Plane Power and B&C alternators. https://www.myrv10.com/N104CD/mainte...cts/index.html

"We uniquely modify each alternator..."

Sheesh. Talk about seeing how the sausage is made. Were the previous generation B&C alternators also internally hacked like that?

Yes and I believe that Bob Nuckolls wrote about this modification. If I remember correctly, that modification creates the overvoltage protection that is internal in the Plane Power alternator. It's the reason I asked if the ACS regulator has the modification. Hope it does as I've got a bad one on my shelf that I'd love to get fixed and Plane Power said parts were not available.

Can someone please confirm that the regulator from ACS DOES have the Plane Power modification? Perhaps, since some carry the ACS part as a spare, a photo of the part? Just seems very strange to me that PP would tell me that the parts nor any overhaul was available and that a very well known (locally) overhaul facility also told me the parts were not available after searching for a couple of weeks.

I have the plane power 60amp internally regulated alternator from around 2009. I highest volatage I see is 13.2 on the efis with master on/avionics. I see 14.2 if I switch on the E-buss. Is this normal?

[Lenny Iszak]

Todd,

Yes, it's normal. Your efis is likely fed through the ebus diode, which creates a voltage drop. Once you turn on your ebus switch it sees bus voltage.

You can improve the voltage drop by using a Schottky diode on the ebus.

The regulator sold by Spruce is the same thing as the original. It's also a Hartzell part number. I replaced mine with one from Spruce. Looks exactly the same with the wire included. They give you the whole assembly with brushes and everything.
