If I remember correctly, I asked the hand propping question of the E-Mag Ignitions folks at AirVenture a couple of years ago. I think the response was to carry a regular 9V battery with you, since it would be enough to get the plane started. That information would need to be verified and the concept would need to be tested, and you would need an elegant way to connect it, but if you plan to be away from civilization, it might be an elegant solution.

Attached is a wiring diagram based on Z-19 but with the addition of a second E-Bus relay. If the engine is started using only one of the batteries, the other battery will prevent brownout of the avionics.

The task is 'easy' . . . just need some details on the hardware you plan to use.

I believe the problem is being caused by contraction of some part of the circuitry. Any tips on looking for the failure point. Likely components, telltale appearance of a connection, things like that. TIA Raymond Julian Kettle River, MN The things we admire in men, kindness and generosity, openness, honesty, understanding and feeling are the concomitants of failure in our system. And those traits we detest, sharpness, greed, acquisitiveness, meanness, egotism and self-interest are the traits of success. And while men admire the quality of the first they love the produce of the second. -John Steinbeck, novelist, Nobel laureate (1902-1968) On 01/13/2015 04:38 PM, rayj wrote: > > Greetings, > > Does anyone know how the voltages of AA disposable lithium batteries and > AA alkaline compare at temps in the neighborhood of -20F. > > I'm trouble shooting a weather station with an intermittent problem and > wondering if AA lithium will give more voltage/current, and possibly > solve my problem. > > Thanks, > > do not archive > ________________________________ Message 7 _____________________________________ Time: 05:03:13 PM PST US Subject: AeroElectric-List: hair wigs for women From: "sulemacheu" fahionable way of dressing up your hair with the most refreshed hairstyle is on its way to provide you the fairy appearance without any harm to your own hair! the hair wigs for women (http://www.hairwigsall.com/categories/Women%27s-Wigs/)I bought here is perfectly convenient and saved me lots of extra trouble and energy on daily hair dress! it is being featured with the glamourous outlook and selling at the reasonable price now! hope this will help to invest for the bargain!
