Hey there everyone, My apologies for the multiple posts on this; my webmail service and email server was arbitrarily placing mails into a junk folder that was not accessed by the POP3 download so I was not seeing any replies and was getting very frustrated! For your interest here is a bit from a post that I made on another forum. Thanks to all of you who have sent messages of congratulations! ****************** I was also most pleased to hear that the storm scope worked well- the antenna for that (very complex with a whole bunch of individually screened twisted pairs in an overall screened cable) was wired one bitterly cold evening at 3am in the Springs hanger as the guys bashed and moved the airframe around getting the wings installed! The aircraft has an unusual fitting as well- a hooter; this was Mikes idea which he thought might help to scare birds away when flying low level near the coast. That was wired up that same evening a couple of hours earlier - Mike was under the aircraft on his back and the guys were trying to manoeuvre the wing into its slot (extra layers of paint was making this difficult and they had to keep removing it and sand paint away...). Without thinking I switched the DC Master on and pressed the hooter button. Mike must have been concentrating fiercely because he shot out and up from under the aircraft yelling 'yah, yah, yaaaah!' He had got one heck of a fright. It provided a laugh and a slight warm up for all of us. :lol: ***************** ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Jay Hyde HH Enterprises Aircraft Manufacture, Engineering and Flying jay@horriblehyde.com Mobile phone: 083 300 8675 International: +27 83 300 8675 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Jay Hyde Sent: 23 July 2009 10:56 PM Subject: RE: AeroElectric-List: Re: Wild flights... 22 hr trip in an LSA over the Atlantic...

    Subject: Voltage Drop / amp ?????
    I have wired my RV7A with the 13/8 revision L. I did modify it to include the LR3C Alternator controller in place of genric Ford Regulator and the AEC9005-101 Low Voltage Module. In looking at the 13/8 revision Q there is an addition of a S704-1 / diode combo added to the Main Battery Bus / Endurance Bus / Endurance Bus Switch. I also have noted that a AEC9001 Schottky Diode can be used in place of a bridge diode. As I noted in a previous email. 1. When the master switch is closed the voltage shoes around 10.8 volts with rock solid amps indication on the Dynon D-120 EMS. From this I deduce that your Dynon is measuring the e-bus voltage. Indeed, with master switch ON and alternator not running, the main bus would normally be a about 12.5 volts. An expected 0.7 volt drop in normal feed diode produces an e-bus voltage on the order of 11.8 volts. When the endurance switch is closed the Voltage moves up to 12.8 or 12.9 and the amps meter begins to fluctuate. Open the Master Switch thus having the load go to only the endurance bus side the voltage maintains at 12.8 to 12.9 volts and the amps still fluctuates. Okay, with the alternator OFF the battery-only voltage would be expected to fall in this range. When you say the amps "fluctuates" what's the max-min numbers displayed? This situation happens with or without the engine running. The battery maintains charge. With the engine running, do you turn the alternator ON to see if it elevates the bus to the nominal 14.2 to 14.6 volts? Since I sent the last email I have learned that the bridge diode will cause a drop in voltage. (Even this 62 year old guy can learn stuff....), but I would have though it would cause the endurance voltage to be less on the endurance bus side not the main bus side with the master switch closed.??????? Then the Dynon is NOT monitoring the e-bus? If you close the e-bus alternate feed switch and the Dynon display goes UP, then it appears that the Dynon is on the e-bus. Now the questions. 1. Why the addition of the S204-1/diode combo added at the endurance bus switch and will it be of value in my configuration to added it? Don't know what an S204-1 device is . . . and don't know why ANY diode would be wired to the e-bus alternate feed switch. 2. Would it be of value to added the Schottly in place of the bridge diode? Slightly . . . but from the readings you cite it's not clear that the Dynon is connected to the Main bus . . . hence SOME degree of bus votlage suppression would be expected. I would think yes if the voltage drop is less and thus give a more accurate voltage reading. The voltmeter is already ACCURATE. It's showing the votlage at where ever it's attached. I'm guessing the e-bus. So all other things being normal and functioning to design goals, the readings are expected and normal. 3. Why the higher voltage drop on the Main Bus as compared to the Endurance Bus? With engine not running and alternator OFF . . . Get out a voltmeter and connect the (-) lead to the battery (-) or to airframe ground. With master switch ON, E-bus alternate feed switch OFF, measure and record main and e-bus voltages. Turn E-Bus alternate feed switch ON and repeat the measurements. Leave B-Bus switch ON turn master switch OFF and repeat the measurements. With engine running and alternator ON . . . With master switch ON, E-bus alternate feed switch OFF, measure and record main and e-bus voltages. Turn E-Bus alternate feed switch ON and repeat the measurements. Leave B-Bus switch ON turn master switch OFF and repeat the measurements. 4. Why the conflicting amp reading between the Main vs Endurance Bus. I don't know WHAT your amp reading means nor how big the fluctuations are. These are digital instruments with quantitization errors that may well display some tiny wobble in readings even when the actual value is steady. Are the strobes running? This would cause an explain a jumpy ammeter reading. Thanks in advance for any help in this matter We need DATA under various configurations in order to deduce the whether the system is wired as designed and whether or not the components are functioning as expected. Bob . . .

    Thanks Bob for the info. My next trip to the airport will begin the process of trouble shooting as you suggest. In regards to this part of the email I made a typo.. Now the questions. 1. Why the addition of the S204-1/diode combo( should ha ve been S704-1 / diode combo) added at the endurance bus switch and will it be of value in my configuration to add it? Don't know what an S204-1 device is . . . and don't know why ANY diode would be wired to the e-bus alternate feed switch. > Date: Thu=2C 23 Jul 2009 13:39:00 -0500 > To: aeroelectric-list@matronics.com > From: nuckolls.bob@aeroelectric.com > Subject: RE: AeroElectric-List: Voltage Drop / amp ????? > kolls.bob@aeroelectric.com> > > I have wired my RV7A with the 13/8 revision L.

I think the Cole-Hersey guys are still cranking out their equivalent parts in volume. I think these are the devices that Van's offers. >Problems-- > >1) Low Temperature rating. Only 122F max. You could land at Furnace >Creek in Death Valley in May and take off in October. Maybe. This is >primarily due to the Nylon innards. This is a drop-dead reason to >avoid the part. And hundreds of thousands of el-cheeso contactors have been used in airplanes for decades and for some reason, they never seem to have bubbled up high enough on the "problems list" to have been replaced. The max temperature ratings for cited for the purpose of meeting specified design goals over a products service lifetime. The 122F max does not mean that the critter goes into destructive meltdown at 123, 153 or even 200F. We've had numerous discussions on the List concerning ratings vs. limits vs. service life, on a host of products. The physics of the matter haven't changed. That 122F figure is not a drop-dead reason for doing anything. It's a reason to consider the product's suitability to task using a combination of understanding what the ratings mean -AND- demonstrated field history. >2) Not sealed. Not dust proof, or fuel proof. No, not hermetically sealed. But those cans are steel and the caps are swaged on with hydraulics or some form of rolling press. I've opened dozens (not easy to do) for various reasons and have yet to discover a spec of dust. And how many contactors are expected function as advertised while sloshed with fuel? The venerable Cutler- Hammer 6041 series contactors have been around since the late 30's and are less "sealed" or "fuel proof" than the el-cheeso RPM/W-H/Stancor devices. Yet they are still in current production on many of the Hawker-Beech products. What part would you recommend that HBC consider for upgrading their choice of contactors? I'd be pleased to forward your recommendations to their VP of Engineering. >3) Low interrupt capacity. And what current levels do you propose to interrupt? A battery contactor opens just before shutdown of the airplane when it's parked. How much current does the contactor carry under these conditions? If the service life at full rated current is in the tens of thousands of operations, how much will it go up if you only open it during shutdown of the airplane? 10 Amps? Gee, that's a killer. >4) High hold current---16 ohm coil. Almost one amp. Yes . . . it's "higher" than the EV200, but not nearly one amp. See: http://www.aeroelectric.com/Pictures/Contactors/Battery_Contactor_Temps_2.jpg http://www.aeroelectric.com/Pictures/Contactors/Battery_Contactor_Temps_1.jpg >5) Low hold force. The specifications call for specific orientation. >2G rating? I've not seen that. Please cite the page and paragraph where this is offered. I've done linear g-loading tests on these contactors and was unable to open them at the limits of my centrifuge . . . 10+ G >6) Wildly wrong for B&C to use coil suppression diodes on these. >This causes short lifetimes on the B&C parts. Absolute BS. I've demonstrated many times that the assessment that you and others have offered on the diode suppression issue is without foundation in the simple ideas and physics behind the design and incorporation of these devices. You guys read specs, and then demonstrate your lack of understanding by posting a "doom-n-gloom of the day" article that does NOT demonstrate or explain where I'm wrong. >7) Not designed to open against voltages above 36 volts. (So forget >the B-lead applications) For normal operations, the b-lead contactor is not subjected to more than 36 volts. When operated as recommended, the service life on an el-cheeso contactor in the b-lead is not at risk. However, during an OV runaway, you damn betcha the contactor is expected to open at more than 36 volts . . . and why should we care? If the OV protection system does it's job . . . and just assuming that a couple of high-energy opening events for the contactor is going to trash it . . . do I care? >See: www.stancor.com > >There are better ways to go.

Should you use them?....not on my bird, Bubela. Your choice are your own and I wouldn't dream of attempting to dissuade you from exercising the right to make them and enjoy the consequences therefrom. But your participation here on the List needs to offer more than your opinions based on poor interpretation of spec sheets, understanding of design goals and knowledge of demonstrated recipes for success. >Better yet, avoid all contactors and use manual switches if you can. > >"Facts do not cease to exist because they are ignored." ABSOLUTELY! . . . so why do you continue to ignore that which I have offered on this topic for years? Make my day, show me where I'm wrong. Bob . . .

The normal e-bus feed path diode shown on Figure Z-11 . . . http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/Z11M.pdf shows an isolation diode between the main bus and the endurance bus. The purpose of this device is to PREVENT the main bus from being powered up from the E-bus during battery-only operations. If you're subscribing to the design goals described for the endurance bus, then this diode is necessary. Do I deduce correctly that this diode is not presently a part of your current configuration?

    From: "Matt Prather" <mprather@spro.net>
    >From the discussion, I still haven't seen evidence that either alternator is putting anything on either bus - the voltage reported doesn't correspond with them charging - I think that's what I was saying before. Maybe they are charging, but no values have been reported that would indicate as such. It doesn't sound like you have a design or component selection problem - I think you have all of the right pieces, but maybe not all of the connections are exactly like they should be. I don't think adding a diode here or there is going to make any difference. I suppose it is possible that ended up with a diode some place there shouldn't be - but that means it wasn't put together according to one of the Z-diagrams. >From my experience debugging problems like this, it always helps to have an extra set of eyes (hopefully with a brain behind them) to which I explain how the system is supposed to work. I'll take the wiring diagram (do you have one?) and point to each item on it and then to each item in the real system. Then I point to each wire (connection) on the diagram and then point to each wire in the system. Sometimes I'll even grab each wire and tug on it a little to make sure I can tell where it's routed. Often (the) problem(s) will become apparent well short of going through the whole process. If I uncover something I don't understand I'll make notes about that (sometimes just writing it down helps figure it out), and then find someone I can explain my question to - even if they probably won't have an answer. I'm interested in seeing values for each of Bob's queries. I suspect the solution to the problem may become apparent to you while taking the data.

    Subject: ZU-TAF: Belem To U.S. Virgin Islands Has Launched
    I see that Mark and James of ZU-TAF fame have launched from Belem, Brasil and are headed to the U.S. Virgin Islands. These two guys and their airplane are incredible! I'm observing their flight path and their present location on Google Earth per Jay Hyde's earlier posting/weblink, which I'm including below. Thanks, Jay! http://www.airplanefactory.co.za/world/default.asp Simon Ramirez Copyright 2009

    Launched I watched them as they crossed the Atlantic..21 hours! I think they are nuts! They needed 440 liters of gas to make the crossing. They were carrying 450 liters!
