I believe this USB stick has to be connected to a laptop to record data.
Is there a cheap dedicated USB port recorder that would record a few
hours of data for later analysis on a laptop? Perhaps even a loop
recorder that could be pulled after an event or for trend monitoring.
Occasionally I would have liked to look at the data from a previous flight.
In my case, I already have the data that interests me available from the
EIS via an RS232 port but it is not recorded unless I run my laptop in
flight which is not practical on every flight. I do have a cobbled
together standalone data recorder for temporary specific items. Data
display and analysis is quite time consuming with the affordable or free
software that I'm aware of though.

It depends . . .
There are stand-alone "USB Data Loggers"
tailored to a variety of tasks. E.g.
http://tinyurl.com/q2o97dd
depending on the kind of signal, conditioning
of that signal necessary to port it to the data
logger (the range, resolution, sample rate)
and number of channels, the general answer to
your question is yes.

Got to http://www.ikalogic.com/ and have a look. I use the Scanalogic-2 20 MHz Logic Analyzer in my hangar for monitoring and analysing data. They have a newer unit now available, faster and more channels.

The ground, at the very left side of page 1 above the alternator, is shorting out
the electrical system.
The voltage regulator enable terminal has two wires attached to it. The shortest
of the two wires is in parallel with the alternator field switch and prevents
the switch from opening the circuit.
Alternators have internal diodes. An external reverse-current diode is not usually
installed. The diode could get very warm depending on the type of diode
and current through it. Will that diode have any affect on voltage regulation?
Is 10awg wire big enough to handle full alternator output current without over
heating?

The title that says, "Bearhawk"? There is a Bearhawk Patrol, but I am not familiar
with a Bearhawk Pacer.

Marvin;
Couple of comments;
Don't understand the second battery depicted as a panel common ground buss??
(Also depicted with negative terminals at both ends??)
On the voltage regulator, the ground, enable, and sense terminals are all
tied together and also to both ground and battery power. This will either
blow fuses, trip breakers or release valuable smoke from the wires. Also as
shown, if the ground is corrected, the alternator field switch has no
control as there is an alternate path in parallel from the first fuse on the
main buss. (labeled main?? Hard to read?) This part of the circuit will
simply not work as shown.
Wire sizes seem a little strange. Some are marginally small others
excessively large. How were these chosen??
The main battery symbol is shown with two positive terminals. The right
hand, grounded terminal should be negative. (short line as opposed to long)
(semantics, I know, but- - )
A single switch removing all avionics power is generally considered a bad
idea as it is a single point of failure. (although used on many production
aircraft for years.) (your choice, it will work, but - - )
The reverse current diode really serves no purpose as the rectifier diodes
in the alternator are in series with it anyway.
