I have received viruses (worms really) from several different "legitimate" sources
on the various Matronics mailing lists. My supposition is that one or more
people have machines that are are infected with the new breed of "super snooper"
worms (no, I did not make up that name) which collect email address. The
mail probably doesn't even come from the email address you identify.
The best thing you can do to combat this is to make sure you have a good anti-virus
program running on your computer and keep it up-to-date. This is no longer
a luxury but a necessity.
On a related note, you probably want to get an anti-spyware program too. The best
one, Spybot Search & Destroy, is free and available from:

Very good. If your battery goes on firewall, then I'd
recommend a single point ground kit on firewall. See
various sizes offered at:
http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?26X358218
(these will be down from the top of the page)
Run battery (-) cable to big brass bolt. Run crankcase
ground strap to big brass bolt. Remove any bonding
jumpers across the engine mount shock biscuits. Run
grounds for all panel mounted items to ground block.
Ground landing lights, taxi lights, nav lights,
pitot heaters and strobe power supplies locally to
airframe. Antennas are only other appliances that
may ground to airframe (follow manufacturer's installation
instructions).
In a two-paragraph nutshell, this is a description of
a grounding philosophy with a high probability of
zero noise difficulties.
I will invite you to join us on the AeroElectric List
to continue this and similar discussions. It's useful to
share the information with as many folks as possible.
A further benefit can be realized with membership on
the list. There are lots of technically capable folks
on the list who can offer suggestions too. You can
join at . . .

Regarding the virus alert mentioned by Brian Lloyd;
I've found no better Anti-Virus program than the F_R_E_E
Personal Edition of AVG from Grisoft. Use the link below
& find the F_R_E_E download of the Personal Edition:
http://www.grisoft.com/us/us_index.php
I've used both Norton & McAfee & a couple others, but,
this program has always scored higher & found more of
the problems & protected my machine better than any other.
(Even used the one from CA before they went commercial)
Plus, it is T_O_T_A_L_L_Y F_R_E_E.
Highly recommended.
George
P.S.: I also use Spybot Search & Destroy 'cause it works.!

Thank you for that. I had AdAware on my system, but was getting horrible
problems just trying to boot up. I downloaded Spybot at your suggestion,
it removed 734 pieces of spyware. Now I can put off buying a new computer!!

Good Evening Stan,
This is a different Bob!
Unless you have a diode in the circuit that will drop the voltage, or some
other method of isolating the system to be checked from the rest of the
system, it should read the same everywhere.
I suppose there could be some trouble shooting capability by using pick ups
at various points around the system. However, as long as the wiring is
properly done and in good condition, all voltages will read the same.
Happy Skies,
Old Bob
Different Bob,
Thanks for your reply. I don't want to sound like I'm trying to build a whiz
bang commercial jet, but in the commercial jets we can select various points
in the electrical system such as generator 1, generator 2, APU generator,
battery, battery bus, standby bus, etc., and each selection indicates what the
volts/amps are at that particular point. For example, one can select generator
1
and read the output - I guess much like a meter I might use in my shop to
check electricity. It seems as though such a setup could be useful for
troubleshooting and for general monitoring of the system. How does one "sample"
the
electricity at several locations?

Good Afternoon Stan,
I think you will find that it is relatively easy to wire up a load meter to
check the voltage and current flow from various sources, but you can only
check voltage when the sources of voltage are isolated. Not sure what kind of
Commercial Jets you are flying, but all the ones I flew required that we
isolate the systems to be able to check available voltage. As long as they are
all
hooked to the system, all voltages will be the same other than for those
cases where an intentional voltage dropping device is built into the system.
However, the ammeter will show the loads that each source is putting out or
receiving as the case may be.
Somewhere in the recesses of my ancient mind, I do recall that the 737 had
"break before make" switches so that various systems could be isolated. Most
other commercial aircraft I flew fed everything to the same primary busses and
that made them all read the voltage of the highest voltage source. Remember
all the paralleling problems on the 707/720 and 727?
I suppose as long as you kept one side isolated from the other, the voltage
could be checked. Seems like there was some of that capability on a few of
the other jet transports I flew. It's been a while!!
Happy Skies,
Old Bob

To monitor voltage from 6 different sources, you need a piece of wire from
each source you wish to monitor (batt, alt, main buss etc). These sources then
connect to a rotary switch connections 1,2,3... on the switch. The common of
the switch goes to the positive voltmeter input and the negative of the
voltmeter should go to firewall ground buss. You might want to consider using
24
AWG wire and build Bob Nuckolls fusible links and run 20 gauge for the batt
and alternator wires. The other voltages you wish to monitor can be taken off
of the output side of any breaker, such as the ess. buss XM Radio breaker,
for example. This would allow the feedwire to be fused by just by default.
As for amps, the traditional way uses shunts. It is lot more involved and
Bob Nuckolls gives a much better description than I can.

This isn't Bob either, I posted the original question.
Re. V-metering
I will be doing exactly what you are asking, I am now looking for a
reliable small multipe position switch to read V from different locations
(locations with normal V and with V drop).
Re. the ammeter part, you'd have either to move the shunt to where your
reading would be (not a practical idea) or to have various shunts where you
want to read and to move the V-meter from shunt to shunt to read Amps.
Regards
Rumen

Bob,
How about reading from numerous locations with a selector switch? I'd like
to read volts and amps from several locations such as battery 1, battery 2,
alternator 1, alternator 2, main bus, ess bus, etc. Can I assume that is not
terrible difficult to do?
