Well, it has been kind dead on this website for awhile. Thought I would start
a new dialog. Many electrical troubleshooters have been stumped and frustrated
by a problem that turned out to be something very simple. Maybe some forum
members would like to share their experience.

I have an LED in my panel that I want to illuminate on Low Volts. I found Bob's
AEC9005 module on his website and would like to buy/build one. Does anyone
know if they are available and if not, how about the board. I believe I can probably
find most of the parts but they won't do me any good without the printed
board. Anyone know of any alternatives? Thanks.

Joe,
Glad you opened up this "thread".
Odd mysteries of electrical problems come in all sizes and will never end.
Fast little electrons running thru all sorts of mazes are bound to find a
black hole or change at the oddest times. . .
One of my experiences that turned out to be dead simple kept me grounded for
2 days in a remote airport.
I landed my Cessna 185 in a farmers strip to visit one of my sons and family
that was only 5 min's away. The flight in was normal and this airplanes
electrical system was stable. Two days later, when I fired up to leave, I
had no alternator output. . or, so I thought. I was there with only simple
hand tools and no instruments to diagnose the problem. I could not find any
wiring breaks, i.e. the field wire breaking from vibration, etc. So, with
my pitiful few tools, I took the alternator and regulator off, called my son
and he drove me to finally find an auto shop to test same. Both units
tested fine. I reinstalled them and made sure the belt was not slipping and
then, counted all the skin that I had left doing this in and out thing.
I had some spare wire, so I began to do some connection jumping and found
the problem.
This Cessna had its original main 60 amp circuit breaker. These are the
non-pullable style, but, they do pop out when triggered. The breaker
outwardly appeared fine. But, when I shorted across it, the electrical
system came alive showing charging current. How odd that the CB opened up
but, did not trigger the pop-out indicator. Later, it was determined that
the CB had not opened due to excessive current, but, failed anyway. Reason
unknown. . .
In this case, I had no options for replacing it until back at my home
airport and I did not want to install the shorting wire. So, I removed the
battery stayed an extra night with my son while topping off the battery's
charge. Reinstalled the next day and flew the 3 hours home with the panel
turned off. Only turned things back on for radio announcements for landing
and taxi.
If I carried my normal "kit", VOM and tools, this would have gone a lot
quicker to diagnose. . . .

I know it's 'after the fact', but the auto parts store probably would
have had a 12V test light & some hookup wire for cheap, or at least the
wire & a 12 V bulb. Would have made the chore of finding the problem a
bit quicker. (You'd have seen the 14V on the source side of the alt
breaker, & known that the alt was working.)

Are you flying yet? If not, what is the anticipated
first light under the wheels?
I'm wrapping up about a half dozen AEC products for
addition to the B&C catalog . . . one of which is
a 4-function module that will manage an aux battery,
annunciate low voltage, manage an ov event on a pm
alternator or manage a battery contactor to minimize
power consumption.
http://tinyurl.com/peyfl8s
If you would like to be the beta-test aircraft for
this product, I'll offer you one free of charge
in exchange for your user-evaluation of the installation
instructions and product performance in the selected
application.
