You drop to e-bus loads, open battery contactor, turn SD-8 on and continue to airport of intended destination. If the SD-8 is not overloaded, the lv warning light will go back out." With regards to the SD-8 and the lv light, Z-13 has a single lv light on the diagram. The descripton for the PV/OV crows foot kit available from B and C states that "The PM/OV was designed to give over voltage protection to the permanet magnet alternator. The yellow light will annunciate if the alternator switch is left off, or the crowbar over voltage protection has been tripped. " So, will the single lv light depicted on Z-13 light if either the main alt or the SD-8 are off line? If the SD-8 has its own unique lv light as described on the B and C site, does it light if the aux alt selection switch is OFF? Or, does it only light if the aux alt selector switch is ON AND the SD-8 is off line? If the first case is true, during normal operation, the aux lv light will alway remain lit which would not be an ideal situation.

Working hard isn't enough. People need the freedom to keep as much as they earn as possible and to keep government out of their lives. China is succeeding despite not having that prerequisite due to their currency policies. In theory, we are allowing these imbalances to occur because in the long run economic prosperity will reform their government. Governments reform in that situation only when not doing so will hurt their economy enough that they have to worry about revolt from their people. The chinese government is getting a free ride and has no incentive to change under the current situation. And no, I don't consider our current economy capitalistic either under my own restraints I mentioned above. That's a problem, not something for other countries to emulate. You can also turn this around and consider it a reflection of great immorality of our elected representatives for not pushing harder for currency reform. This policy just doesn't hurt our country it will deny freedom to Chinese citizens for a longer period of time (assuming china's citizen's ever achieve it). The prosperity in China's city's is not reflected in china as a whole. There's abject poverty for anyone not in the party in rural china. >He recommends that our children learn Mandarin, >rather than Spanish or French.

America only loses in the presence of an unlevel playing field. Once this goes on long enough to hurt our economy enough china's will lose it's main market. c'ya, Michael On Mon, 1 Oct 2007 10:40:58 -0700 (PDT) Michael Pereira wrote: > China's current economic might is based on currency fraud, not cheap labor or > sizable natural resources or individual's desire to better themselves.

This weekend I met up with a friend who flies for Cathay Pacific, based in Hong Kong. Many of his blocks of flights have overnights in various cities in China, so he has observed China first hand for many years. He reports that while the government is still communist, the Chinese economy is very capitalist. The working people want all the stuff that we in the west have, and they are willing to work long days, six days a week to get it. Their economy is growing very rapidly as a result, and the standard of living of many people in the cities is improving very rapidly. He recommends that our children learn Mandarin, rather than Spanish or French. He believes that China's economy will eventually dominate that of the western countries.

How do I size the diodes for the 12 V portions? for the the timer relay, switching 120 VAC, with a 12VDC coil? / + ---+---o o---+------+----------+ | S1 | | | | | [Relay1] |> | <-Relay | | | | Contact | | | +-------+ | / | | | | +---o o---+--|<--+ | [Motor] Park D1 | | | | +---|<--+ | D2 | | S2 | Gnd -------------------+---o->o---+--+---> Trigger | | Signal Timer Relay Contact-> '-> | | to timer | | +------+ How it works: When in the park position, the park switch and S1 are both open. Pressing S1 energizes Relay 1, its contact closes, the motor moves and the park switch closes, keeping Relay1 energized until the mechanism moves back to park. When the mechanism reaches the S2 position, S2 opens and removes the (-) trigger signal to the timer. After 30 seconds, the timer relay de-energizes and the relay contact closes. That causes the motor to run again, moving away from the S2 position and closing S2. That sends the (-) trigger signal to the timer which energizes the timer relay. The mechanism returns to the park position, which opens the park switch and de-energizes Relay1, and the motor stops. Diode D1 protects the switches against the inductive spike created when power is removed from Relay1; D2 protects against the inductive spike from the motor when power is removed from it. The timer relay coil should also have a diode placed across it, wired the same polarity as the other diodes (banded end connected to the + side). ________________________________ Message 4 _____________________________________ Time: 03:37:06 PM PST US From: Jeff Page Subject: AeroElectric-List: Wire specifications I am building a Dream Aircraft Tundra (4 place aluminum bushplane) and am confused as to what wire to buy. Most wire comparisons list TKT as being the only thing that is wonderful. However, most companies seem to be selling Tefzel for homebuilt aircraft. Is there a convenient source of reasonable lengths of TKT wire ? Thanks !

Why do you want TKT? M22759 Tefzel has been the wire of choice in Wichita for tens of thousands of airplanes for about 25 years.

Unfortunately, I have no CAD experience, and don't know how to use TurboCAD. The TurboCAD interface has an Internet link for Tutorials: http://www.turbocad.com/tutorials Unfortunately that web page doesn't exist. I have searched the IMSI website for tutorials, but cannot find anything. I note that there is a Tutorial folder in the TurboCAD folder that loaded with the program. But w/o the tutorial narrative, I don't know what to do with these sample drawing files. Does anyone know where I can find the tutorial files that (apparently) used to be available from the TurboCAD people? If I could just find them once, I could use the FireFox Scrapbook utility to make my own copy of the tutorial files. Thank for any help you can give me.
