HelloBefore one week I found 2 original clocks from Boeing 757.You know someone how can i make the clocks to work?Behind of the clock have one connector with 24 pins.(see attach photo)Have someone any infos about the wire?Best RegardsLambishttp://www.projectmagenta.com/~lambis777project/

Lambis, I am a Bench Technician for Aurora Avonics in Texas, I have seen a few "red tagged" boeing type clocks sitting on shelves. To say this there is no way we would know the exactly information about this clock without having a manual that has a circuit, wiring diagram/schematics or theories. If you have knowledge or experienced in some electronic theories. The crucial thing that you should look for is the 28V and common ground line, this would make the clock work. The only thing I would suggest you is contact with Boeing Industries and see if they can fax or send you the information, or you could try and test it with ohmmeters. Good luck

Hi Someone else tell me this instrument need 115 volts 440 cycles.When I am very despair and I don`t have found any info yet then I contact with the Boeing.Thanks>Lambis,>> I am a Bench Technician for Aurora Avonics in Texas, I>have seen a few "red tagged" boeing type clocks sitting on>shelves.

Try asking Matt Ford about it. I think he has worked with the Boeing clocks before.I would be careful about calling Boeing too... I called a lot of aero companies even before 9/11 and was always asked the same questions... "And who are you with??" or "Do you have an FAA license??" I'm not saying don't do it, it's just advice from personal experience. Make it a last resort for sure. Also, make sure the clock is actually made by Boeing. Most of their parts are out-sourced. If the clock is not actually made by Boeing, you can usually talk the company into sending you diagrams and schematics. Otherwise, you may just want to take to clock apart and see what goes where. That's how I learned how to use half the junk in my sim :-)Roberthttp://www.777Project.cjb.net

Lambis, Robert's right... Disregard on my last statement about calling Boeing industries I know they have strict limit sharing out the tech infos. But there are some other companies that would be willing to share you out some information on boeing parts that is not in use or is "red tagged" as of today such as B747-400 clock that sits on the rack at my work. Today One of my co-worker, a senior technician. Showed me a circuit diagram/schematic of Boeing 747-400 clock He metioned that it needs 28V to get that motor to synchronize. And 119VAC for everything including the A/D or D/A converting, displays combination and etc. I asked my co-worker if he could get me a copy of 747 clock shematic so I can share it out with you. But unfortunately, he told me according to agreement between Boeing Industries and Aurora Avionics. No techs are allowed to make a duplicate of any boeing schematics. But, my co-worker also said, either way if you re willing to take tough steps is by looking at the back of clock for a serial number and model type. Contact with FAA to see if they would allow you to have a special permission so you could get some information on the clock. FYI that would be costly! Or another step like Robert and my coworker said, take clock apart and see what goes there, what makes it work.Good luck
