Subject: | Mooney Alternator woes |
My hangar neighbor is trying to figure out why his alternator occasionally drops
off line - requiring a weird reset sequence. He has to shut off the battery
and field, then go to a low power setting and bring it back up again. Something
about resetting an overvoltage protection device.
It is an M20S with Cont 550 and gear driven alternator. The first regulator lasted
only a couple of years before giving up the ghost and the replacement was
a special from Mooney.
My first line of thinking is to locate the regulator and test it. Nobody knows
where it is hiding.
(I'm in DC - the plane is in DE...I'll be home next weekend to help more.)
Meanwhile, does anyone have an electronic copy of the Light Plane Maintenance article
on troubleshooting alternators...and the Mooney M20S maintenance manual?
If we can find it, I'm hoping that we can determine if the regulator is the culprit.
Thanks in advance,
Ralph
RV6A N822AR in N06 - waiting for my engine/prop to come back from overhaul after
being hit by a flying hangar door!

The LPM article is not likely to be much help. It
will be VERY generic. If it were my airplane, I'd
jeep another regulator in place of the original to
see if the problem goes away. Given the rarity of

Thanks - first step is find the installed regulator. I could probably sub-in the
B&C one from my 6A on a temp basis to see if it works - that'll be a good starting
place...good idea.
I'll ask about the reset sequence to see if it is in the POH.

Subject: | Shorai Battery Review |
Bob et al,
These Shorai batteries are gaining market share in the motorcycle sphere.
Still only anecdotal info as to their safety, longevity and failure modes.
That being said, at 25% of the weight of AGM lead batteries for the same
capacity they offer real advancement in energy storage.
As the numbers in service increase in the ground transport market more
experiential data should become available.

Subject: | Should battery be charged with a higher voltage? |
An RV-12 owner recently asked a question on VansAirforce about the charging voltage
for the Odyssey PC680 battery. It seems that all of the voltage regulators
that come with the Rotax 912 are factory set at 13.6 - 13.8 volts. The regulators
are sealed; thus no adjustment is possible. This RV-12 owner wanted to
know if the battery should be charged with a higher voltage. So I did some
testing.
I charged up my PC680, and then disconnected the battery charger on Tuesday.
On Wednesday I measured the battery voltage with no load. My cheap meter read
13.01 volts and my Fluke read 13.09 volts. Then I went flying, did some touch
& goes and gave a couple of rides. A total of 1.75 hours accumulated on the
Hobbs and the engine was started a total of 6 times during the day. The starter
uses very little power because the engine starts with only one revolution
of the prop. The longest flight was about 30 minutes. At cruise, the Dynon
D-180 indicated the normal 13.6 volts (which is 0.2 less than what my handheld
voltmeter reads.)
The next day, Thursday, I measured the no-load PC680 voltage: my cheap meter read 12.98 and the Fluke read 13.06 volts. The Odyssey Owner's Manual http://www.odysseybattery.com/documents/US-ODY-OM-010_0412.pdf
says that the battery is 100 percent fully charged when the open circuit voltage
is 12.84 or higher. Since my battery voltage is above 12.84, I have come to
the conclusion that the Rotax voltage regulator setting of 13.6 - 13.8 is adequate
for normal operations. If the battery is ever discharged for some reason,
I intend to fully charge it before flying.
Have I come to the correct conclusion about the regulator setting?

Subject: | Shorai Battery Review |
They certainly look and sound the part but Lithium Batteries are prone to
catching fire that is why there is a prohibition on transporting
Them in the holds of Aircraft. The other thing to mention is that such a
light battery will alter your C of G position so you would need to re-do
your weight and balance
Chart.
So maybe more info and a bit more testing or time may be required to
establish their safety..

Probably not without a step-down transformer/voltage converter. If you can't find
a charger-maintainer for your 240v world, you can find voltage converters
on Amazon or E-Bay.

John;
The international version is model SC1200A, spec sheet attached. (I hope)
Couldn't find a quick source or price, but this is a similar charger other
than the input is 120-240VAC 50/60Hz
The 1562a is 120VAC 60Hz only.

They are certainly impressive in terms
of performance but not yet ready for prime
time in the TC aircraft world. Check the
List archives for 5/10 to 5/15 of last year
and the term "lithium battery".
Cessna spent a bucket of money on a Li-FePOH
battery STC and had 50+ airplanes in the field
when they experienced a ramp fire on one of
the lithium installations.
I'd like to run one in a car . . . or motorcycle
but I don't think I'd put one in an airplane
yet.

Yes. A SVLA battery will always charge to 100% of capacity
with a 13.6 to 13.8 volt bus. The reason bus voltages are
set higher is to shorten a cycle time for recharge after
a deep discharge.
But if you always take off with a very lightly taxed
battery then the lower set point is fine.

Hi Joe
I have a Rotax 914 not yet flying. I am going to raise the effective
set-point on my Ducati regulator to make my Odyssey PC545 battery a
little happier.
Add a diode:

Read the manual on Odyssey:
http://www.odysseybatteries.com/files.htm
Click documentation, you will see that a little higher is desirable.
