Oh, absolutely...I forgot to mention that was at no load. 12.6V with
some load on it seems reasonable to me (that's what I usually see on my
battery I use when I take my ham radio gear portable "in the
field")...We have a handheld load tester at work...looks like something
that would be bought at an auto parts store. I assume it is a high
wattage resistor that puts a load on the battery and you keep it on for
a certain period of time and watch the meter on it. If it stays in the
green area, the battery is "good"...

I saw between 12.6 and 12.8 at zero load. (Measured at the "always hot" aux
power plug).
With the system charging at 14.2+ volts, what does this tell me?

And available reasonably inexpensive at Harbor Freight. I have HFs
trickle chargers with a desulfator to float charge batteries when not in
use for extended periods. I figure that if I get twice the life out of
a battery this way, the first battery I save pays for the
charger/desulfator. I've only 'recovered' one battery that failed the
load test. It seems that prevention goes a real long way to extending
the battery's life. Sealed batteries (the no maintenance kind like gel
cells) suffer from lack of water over time rather than plate damage.
I've bored holes in the tops of gel cells to be able to add water (after
they're 'bad') with really good results. These batteries go into the
lawnmower or my mogas caddy ..... where failure doesn't really impact my
day.
And, why we're here, your batteries that sit on the firewall suffer
vibration damage more than the ones mounted behind the pass
compartment. Dynamic balancing of prop/engine goes a long way to
extending the life of almost everything on your airplane.

| Subject: | Re: Fuel Flow Sensor |
Don Rivera at Air Flow Performance recommends placing the sensor
between the fuel servo and the flow divider. In most cases this
would mount the sensor vertically. I questioned him about this and
he said, he tested it and it really makes no difference.
I like the idea, because it seems to be the easiest solution. But,
at this time, I do not have a need for a fuel flow data so I have not
installed one.

My flow sensor is mounted vertically as described below and is functioning
perfectly.
YMMV,

| Subject: | Fuel Flow Sensor |
Hey Vic,
I put mine inside the firewall downstream of the electric fuel pump. Works
fine, I think the directions were written by a lawyer, say that it need to
be between the mech fuel pump and the divider. As I have to of the same se
nsors on my boat installed prior to the mech fuel pump drawing more gph for
the last ten years without a problem, I think this location will be suitab
le on our planes as well.

I'm doing the intersection fairings and those who have "9-A" airframes,
how did you attach the upper intxn fairing to the fuselage? The lower is
glassed to the speed pants but the top one?
