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.

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. Stan Sutterfield 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.

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.

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. Todd ________________________________ Message 8 _____________________________________ Time: 08:49:11 PM PST US From: frequent flyer Subject: AeroElectric-List: 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.
