    Subject: Re: E-Bus Diode & Fuseable LInk Question
    From: <longg@pjm.com>
    Henry, I too am installing the e-bus diode. B & C directions show a jumper between two of the fast tabs on the diode while Bob indicates one can just cut off two of the tabs and use the +/- connectors (See page 1-9). This comparison gleans one bit of information from the diode and that is the fast tab bi-polar to the others is positive. This definitely connects to the e-bus. Ok, that's easy - Bob shows the tab opposite to the + (presumed the neg side of the internal diode) is negative and presumably connects to the master bus. B & C jumps the two opposing terminals and wires them directly to the master bus. Someone should decide how these things really wire up. Perhaps they work either way? Glenn -----Original Message----- From: owner-aeroelectric-list-server@matronics.com [mailto:owner-aeroelectric-list-server@matronics.com] On Behalf Of Henry Trzeciakowski Sent: Monday, May 26, 2008 7:53 PM Subject: AeroElectric-List: Re: E-Bus Diode & Fuseable LInk Question --> <hammer408@comcast.net> Bob: I purchased from B & C their E-Bus diode with 15 watt heatsink and installed between Main Bus & E-Bus per your Z diagram. What I'm confused about is that their wiring diagram has 1 wire originating from a fast-tab on the diode to the E-Bus - NO PROBLEM SO FAR: then 2 wires from 2 seperate fast-tabs joining together then proceeding to a Circuit Breaker then to the Main Bus....Sooooo I'm a little confused about the Circuit Breaker and why there are 2 attach points on the diode in the first place.!!! None of your Z diagrams show a CB between the Main & E Bus, and why 2 attach points on the diode joining forces? Second questions:: Im installing a Heavy E-Bus architecture, per Z-32. Currently my E-Bus load is around 12 amps...architecture is: 18g F-link at E-Bus---14 awg---S704-1 relay---14 awg---10amp fuse at Battery Bus. According to B & C, fuseable links are for low power, 10 amps or less.....so should I eliminate the fuseable link and directly wire to #10 stud on E-Bus OR wire to a 10 or 15 amp fuse on the E-bus - and increase the Battery Bus from 10 amp to 15 amp? Thanks Henry

The 9011 is designed first to be OV protection for generators but adaptable to alternators. Second, LV warning for the main bus and third, LV warning for an aux battery. All three functions in one box for about $50. One may pick any combination of the three functions to operate independently of each other. I just got home from Medicine Lodge, KS. Had a meeting with my family's banker and CPA about setting up an LLC under which I plan to operate the AeroElectric Connection publications, a line of products for OBAM aircraft (business name to be determined), my son's locksmith activities along with his HVAC services, my consulting services, and a sort of "how can we help you" handy-man service backed up with a great wood working shop. The kids are going down tonight to tour some available house with a real estate agent. We're 99% sure that the whole family will be moved to ML before the end of the year, 95% sure before the end of the summer. Once I have a mechanism in place to hire help and take care of government's penchant for ham-fisted-filching of citizen's property, I'll get the 9011 and a number of new products into production with a goal of turning all but consulting business over to the kids.

    Subject: Corrosion Protection Of Electrical Connections
    I was wondering if there was any sort of recommended corrosion protection application for electrical connections, especially where wires are spliced with solder or d-sub pin connectors and then covered with heat shrink tubing. I found the attached e-mail in the archive, but it refers only to limited use of DC-4 silicone grease for certain situations such as spark plug terminals. Is there any other sort of material that folks are applying to connections as added protection before "covering them up", or is it best just to leave them "dry" and simply use dual-wall heat shrink where there is a concern about corrosion?

Waaaayyyy back when, we commonly filled the mating spaces of coax connectors up on towers with DC-4 before putting the connector together. Use sparingly. You don't want it to ooze out and get the exterior all messy. The stuff is VERY hard to get off and in the case of coax connections, made it difficult to wrap with tape for exterior water-barrier. A coating the top insulator and terminal of a spark plug before installing the spark plug wire would be an assist for keeping moisture out of a potentially vulnerable joint in the system. Same thing would be good for coil end of wire. Silicone greases migrate with time. Put a pea-sized dab on a flat surface and come back a few months later. You'll find a large silicone-grease wetted area around the dab that continues to grow with time. It's a neat stuff but I would use it reservedly with respect to amount and location and only in areas where a connection is likely to be exposed to extra-ordinarily corrosive influences. Bob . . .

    Subject: Corrosion Protection Of Electrical Connections
    From: <longg@pjm.com>
    Dave, Bob has earlier indicated to me that hanging connections out in the open is the best protection of all. Look over your head at those 500KV lines. If they get wet, they'll dry without inhibitors which cover up moisture etc. If you live in a pathetically damp place like I do, I have another trick to help the moisture/corrosion problem. This works in the cabin or in the engine compartment. Take a 25 watt bulb and hang it inside the engine compartment or the cabin when not in use. This very small amount of heat will thwart normal moisture buildup. There is at least one product out there that connects to the airframe and produces positive ions in and around the airplane which supposedly are offensive to rust. I heard they also attract nice women, but who knows.

    Oh now you've stepped in it Glenn ;) And I'm about to... Every decade or so the ion rust protection scam reappears. Even new car dealers are in on it this time.

Also keeps assorted dust, grit and gunk from sticking to the wax and making it less sticky. And I do wash my hands before using the white.

    Any reason to not put my fuse holders on the engine side of the firewall? Is the heat too much?

    Subject: ANL fuse size
    I read in Aeroelectric Connection that ANL current limiters should be sized larger than alternator output. Then I went to purchase one at B&C and read in their catalog that they should be sized same as alternator output rating. Can anyone tell me which is correct? Roger, Tucson, AZ

    Subject: fuseholder location
    I'm planning to do the same thing, mounting small 6-circuit marine fuse panels for the FADEC circuits relatively low down where the at-rest heat at least will be lower. Given that many modern cars have fuse/relay blocks mounted in the engine compartment where it gets at least as hot as an aircraft I expect them to be reliable but like you I would be interested to know if anyone has knowledge of heat problems with quality components on the engine side.

    Subject: Bob's LLC
    Finally something I might share back from 25 years as business/bankruptcy/attorney. This is not legal advice, just thoughts. LLC is good first step, still some questions as to whether a corporation (C or S) is the best for liability protection. More importantly here, be careful of putting all your eggs in one basket. In general, I recommend keeping separate businesses in separate legal entities. It would be a shame to have the OBAM business hit with a claim that originated against the locksmith, for instance. Or when the big national company wants to buy the hvac company, having to separate out the other businesses. Some tax issues there also. Mainly I worry about the cross liability issue. You don't want a single point failure to ruin your entire economic plan. Regards, and thanks again for this internet resource, Skip (Florida) . **************Get trade secrets for amazing burgers.

Actually, the LLC is primarily a way to get me, my kids and ultimately my wife on a payroll for group health insurance. There will be few "eggs" of net worth. Practically all the value is embodied in skill-sets. It's also a way for my consulting income to be distributed the kids and taxed at their rates instead of mine. ML is a town of 2000 where one cannot make a living by being a specialist . . . so it's exceedingly unlikely that any of the specialty services would become attractive to a buyout candidate. We'll carry liability insurance . . . but only enough to buy us representation and not enough to make us a plum to pick. I'm becoming rather poor in a few weeks. My income is going to be less than what I was making when my boss raised my wages by 50% after one of my designs landed him a $multi-million$ fleet retrofit of the Lears . . . that was 28 years ago.

The data sheets are the better guide. See: http://aeroelectric.com/Mfgr_Data/Fuses_and_Current_Limiters/Bussman/ANL_Specs.pdf Not that a 60A alternator on steroids cannot open an ANL35. These are HARD fault protection stroked by a faulted battery (1000 amps!?).

    Dr. Dee and I are headed for a long weekend along the CA coast south of SF. I'm taking a computer along, to service my MP3 player and let me do a bit of writing. The good Dr. told me to leave that WiFi adapter home . . . Yes ma'am! No problem! Be back next Wednesday.

    Subject: Bridge Diodes use
    Okay, if you use the bride diodes to power a device from two power sources. Which one will carry the load? Or will they both share the load in some way? I thought I read or heard someplace that the power source with the higher voltage takes the load but how much? All of it? I hope this question makes sense..... For example if a device draws 10 amps and is powered by bridge diode with power source 1 at 13.8 volts and power source 2 at 13 volts Will source 1 take the whole load all 10 amps ? Or will they share it in some fashion and how do you calculate that ? I ask since I want to make sure I do not over load my two power source config. Thanks Jeff.
