Here's a note I received on one fellows success with
replacing flash-rated capacitors with plain-vanilla
electrolytics.
His confirmation of my past experiences suggests that
the experiment is worth repeating.

Thanks, Bob! My buddy at the airport has offered to look at the board.
He has it now. If he comes up empty handed...(not likely :>))
I will take you up on the offer.

Yes I did the same, I had a pair of Aeroflash units in my old Zodiac.
Standard repair for each Aeroflash was $50. Standard capacitor was $10
and 10 minutes with a soldering iron.
I only used to get a couple of years per capacitor but that seemed no
worse than the Caps the Aeroflashers came with.
Cheers
Frank

| Subject: | Re: Good Deal on Power Guard |
I understand from the manufacturer that it does the same thing as Bob's
concept. It's designed around having two alternators. I don't believe it adds
anything beyond Bob's concept except that it is ready to mount and connect.
Send a note to the builder (via his web site) and ask about the operation.
I bought it before I had settled on my final electric plan and I've decided
to use two batteries instead of two alternators.

Looks interesting. How would this interact with Bob's design for a
electrically dependent engine? Does it buy anything over what Bob's
schematic is doing?
Glenn
If anyone is interested, I have a 12V Composite Design Power
Guard (see it at http://www.compositedesigninc.com/Power_Guard.htm) that
I don't need and I'll sell it at 40% off retail with free shipping. If
you want photos send me a note off the list at speedy11 at aol.com. It
is new, unused and never installed.
It doesn't fit my needs but maybe someone on this list can use
it.

| Subject: | RE: Earth return |
John,
Each circuit needs only one ground. The advantage of using a local
(airframe) ground in a metal airplane is that a separate ground wire need
not be threaded through the structure. If you elect to use a separate
ground wire then there is no advantage to using a local ground. In fact,
there may be a disadvantage because the possibility of ground loops would
then exist.
Regards,

Hi Guys
Can you please confirm that it is good (aircraft) practice to have in
addition to an earth return wire to the main earth 'bus' a local earth
connection, for example, at the wing tip for the navigation and landing
lights.
Best regards - John

| Subject: | Re: Double row breaker panel |
I have done this many times.
Here is the secret. All of the wires..... and I mean ALL OF THE WIRES
must go to one side of the breaker panel. This allows the panel to be
angled 90 degrees out from the panel for very easy service. No need
for a silly 2 foot long service loop.
Did I mention that ALL OF THE WIRES MUST EXIT TO ONE SIDE?
Avionics Installer hell is where removeable service panels have wires
run willy nilly in all directions, so that the panel cannot be moved
away from the instrument panel.

| Subject: | Lightspeed Electronic Ignition |
I have one of the original ignition systems from Lightspeed which was purchased
in 1992 by a friend who is now deceased. I am going to install it on my IO-360
but am missing the manual. I have the newer manual but it doesn't answer
all my questions. If any of you have the manual for the Model CD 4 CYL AEI 42
which was discontinued in 1995 I'd sure appreciate a copy of it.
Thanks, Jack In AZ
