The VR166 type Ford regulator (mid-70's LTD) that 'Lectric Bob shows in
some of his schematics and many of us use is solid-state and doesn't
have any adjustments. Since it only costs about $10 it is easy to
replace if it has drifted out of spec. But they seem to be very reliable
units and mine has been fine for eight years.

| Subject: | Thomasville, GA Fly-In |
This past week-end was the Thomasville, Georgia annual fly-in. This
event has been happening close to 40 years and is one of my favorite
fly-in's to attend. It is a well run event that does not have a real
structured program. It is an aviation social event and the main rule is
for you to have a good time. If you are tired of poorly run events with
bad facilities, give this one a try next year. It happens the second
week-end in October every year and is open to all types of aircraft.
There is also a great private collection aviation engines on the field.
It is always open for viewing during the fly-in and contains rare
engines you might not have ever heard of.
Go to http://picasaweb.google.com/RV455J/Thomasville2007 for a few
pictures from this year.

is their website and they have their own charger, I took the part number
and did a search on Google and saved a bit of money over the factory
site. I use two of the batteries and always keep them charged full up,
as I have an electrically dependant engine.

Hi Kyle,
I have an Odyssey battery in my RV-6A. I was told that it needed to be
charged at 14.2 volts. If it was charged at a lower voltage, it would
gradually loose capacity from being undercharged.
I don't have a source for the 14.2 volts. I didn't find it on the
Odyssey battery website. Anyone know where the correct charging voltage
is documented?
Regards,
Jim Ayers

Subject: RV-List: PC-680 Performance
Over the years, the Odyssey PC-680 has gotten very good reviews for its
small size and high cranking amps. So, about 3 years ago, I selected
one to replace a 4 year old Concorde battery.
My first Odyssey battery became weak after just under 2 years. The
vendor replaced it under warranty.
Today, my ~14 month old replacement battery barely turned the engine
over on a 80 degree day. Sure, the aircraft sat outside in 45 degree
weather last night (Thomasville GA Fly-in - a really fun one), but the
airplane had 8 hours of South Georgia sunshine to warm up, so is isn't
like the battery was chilled or anything.
To get to the point, what is the RV-list's collective experience with
this battery? I know it is light and has good cranking power when new,
but I'm interested in what sort of longevity people are seeing. Is it
lasting 1 year, 2 years, more, or less? I'd hate to go back to the
Concorde, but I'd prefer that to a battery that goes soft after less
than two years.

I think there are a coule of brand new regulators in my shop. I should have both

Randy,
I think you will find that most of the quality 12 volt battery
chargers on the market today chage at the rate of 14.3 or there abouts
so Why don't you go to a place where 12 volt battries are sold and ask
what the charging rate is.

AGM batteries prefer a little higher voltage. Yes, standard battery
chargers will work but are not optimum. Info from their site...

| Subject: | Fuel Flow Sensor |
Hello,
I am trying to find a suitable location for my fuel flow sensor between the fuel
pump and the Bendix injector (between the injector and flow divider is out of
the question) on my Lycoming AEIO-540, At the moment the simplest location has
the sensor longitudinally angled downward at about 40 deg angle (the outlet
being lower than the inlet). This location also ensures a straight line prior
to the inlet. I've read on previous post that it is better to have the sensor
level, how critical is this?
Thanks
Vic

After Saturday's marginal starting performance, I thought it was worth
getting quantifiable measurements on the battery and charging system, so
today I checked the battery and it showed 12.6v. The aircraft had sat
for 2 days since its last flight.
Then, I went flying. The engine's starting performance was *much*
better than on Saturday.
I checked the charging system's performance several times on the ground
and in the air, and the system voltage was always 14.2 - 14.5 v.
After I landed, I let the aircraft sit for long enough to roll it back
in the hangar, and checked it with the meter again. The reading was
12.8v.
So, the question is:
Was Saturday's reluctant start a freak event caused by unknown reasons?
Or should I expect to see more than 12.6 - 12.8v on a "charged" battery?
I know that 14.3-14.5v output from the alternator is within the
appropriate range.
Thanks in advance.

13.2 Volts is considered a full charge on a standard lead-acid battery.
Also, on standard lead-acid batteries, heat can affect their
performance. Most people think a battery is most likely to "act up"
when it's very cold outside. They also "act up" when they are hot (like
in places like Georgia)....No idea what makeup the PC-680s are...

This is true, but keep in mind that 13.2 is at zero load. If you are
reading the voltage by turning on your electrical system and reading the
number off your volt meter, I wouldn't be surprised if there is enough in
your system to draw the voltage down somewhat. 12.6 seems pretty much in
the ballpark.
