I have an Odyssey PC680. Its 18 months old and has been in the A/C as power
whilst fitting wiring and instruments.
Now after a full charge all I see is about 12 Volts and placing a load of 2
or 3 amps on it sees the Voltage drop to about 9.5 V in about 10 mins after
which the EFIS and radio start to fall over.
It has been run completely flat on at least on occasion, maybe twice. I am
using a quality charger designed for AGM batteries. The local battery supply
shop has tested it and gets the same result.
I now have a new one.
Did running it flat stuff it?
Can it be bought back to life?
By the way I paid $240.00 US for the new one, what are you guys in the
States paying. I think the importer is ripping us off over here.

Hi,
I hunted that dog too. If you are going to place a label on the sw, the
guard can block the area intended for a label. Be watching for that too.

I had the same issue on a couple of switches, I just milled another slot in
the threaded part of the switch 180 degrees from the original.

Subject: | E-Bus Source Switching |
I am in the midst of some fairly major work on my zodiac and thought this would
be a good opportunity to split the power distribution into a main and an e-bus.
Rather than an e-bus SOURCE switch and a large diode as shown in the aero-electric
connection, I was thinking about incorporating an AVIONICS-MASTER switch between
the main and e-bus, and had the idea that a 2 pole, 3 position switch would
allow e-bus OFF, e-bus ON, and e-bus ALT SOURCE positions, while ensuring
no back-flow into the main bus from the alt source, thus eliminating that honkin'
diode and its voltage drop. All from just one switch!
Any reason anyone can see not to do this?

Subject: | Re: E-Bus Source Switching |
Hi Dough,
on the fast run 1 major :o)
-single point of failure
The difference between an E-bus and an avionics master is that on the
e-bus you have all essential parts for a save ending of your flight in
case your alternator fails, on an avionics bus you have all avionics
equipment (if needed or not for essential requirements). I have the
diode in place and the voltage drop is not a real problem, it's so minor
and only there when anyway your alternator is sourcing the bus so I see
no issue (if you want you can go to more expenses and get a part which
has only 0.1V drop. The good thing about the diode (or if you have bad
avionics (brownout) the bad thing) you have only one switch to get the
cockpit live, so the KISS principle.

I am told that there is A difference between aircraft terminals and hardware store

Generally on MIL spec terminals there is a metal band that crimps the
insulation, this band is covered by the insulator. On cheaper hardware
store/automotive copies the metal band is missing and all that grips the
wire insulator is the plastic of the terminal.

Perhaps even more important is the quality of the crimper. The typical
hardware crimper isn't likely to give that 'gas tight' joint to prevent
corrosion within the joint.

I have seen spade connectors at autozone that had the metal that crimps the
insulators. There were some other ones that only crimped the wire only but
these looked like they could me of the same type. I did not see anthing on
the package that had any mils ratings on there tho.

What you are looking for is AMP PIDG (or equivalent). On the MIL spec
(AMP
PIDG), the metal part of the crimp sleeve is longer (deeper). They can
look
similar to the cheep HW/auto style from the outside. You have to look
=93into=94 the sleeve and assess the length (depth) of the metal part of
the
crimp area. Ideally, the metal part is long (deep) enough to crimp onto
both the bare wire and the insulation (if done correctly). This is
rarely
the case with the cheep HW/auto versions. On those, only the plastic
part
of the crimp sleeve crimps onto the insulation (which is insufficient to
properly secure the wire). Unfortunately I=92ve found, most
ads/catalogs
usually don=92t clearly specific whether they are the cheep HW/auto type
or
the better Aero (PIDG) type.
See here for AMP PIDG data sheet:

You can get the correct ones from here:
http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?12X358218#s814r8-
10
at reasonably competitive prices (20 - 30 cents each). I=92d be
interested if
you find them much cheaper somewhere else.
These also appear correct:
http://www.aircraftspruce.com/catalog/elpages/insulterms.php Note in
the
photo, the metal part of the crimp barrel is nearly as long as the
plastic
insulation (versus only =BD as long as on typical HW/auto style.

Subject: | Re: ring terminals |
There are three differences between the hardware store variety of
terminals and Mil Spec terminals. As others here have said, there is a
sleeve that grips the insulation to spread the mechanical loads to
minimize flexing where the wire exits the crimp. This is where the wire
will work harden, become brittle and break. Secondly, the seam on the
barrel is brazed closed on the Mil Spec terminals. Many of the hardware
store variety are just formed into a barrel that will open when crimped
unless the crimp is done correctly. The third difference is that
hardware store terminals usually have vinyl insulation. The Mil Spec
demands nylon insulation which will outlast vinyl many times over. In
addition, Mil Spec products are produced under exacting quality
standards.
Go here to find a good variety of Mil Spec terminals and tools that
properly crimp them. http://www.terminaltown.com/
