The failures of contactors that I've seen are failures to activate not failures during flight. I do agree that any truly essential system such as engine power should not be tied to a single contactor but the battery buss and/or essential buss concept seem like a better solution where applicable. Don't forget that a backup has little value unless tested regularly. For example, I test my backup EFI during taxi on every flight and it has always worked perfectly. I happened to test it in flight yesterday and discovered that it has started to miss at high power which pretty much means it has been useless dead weight for some undetermined length of time as I do not often test it at high power settings.

There is no electrical reason why your idea won't work but why do it? Master solenoids don't typically fail in-flight. They typically don't fail at all if installed as Bob suggests, unless the posts are tightened incorrectly and twist the internal contacts. If one does fail, you can find a replacement at a FLAPS. If your engine has magnetos, an inflight failure won't matter. If you are using EIs, you'll probably have ignition power straight off the battery so it still won't matter. Put the cost and the weight-cost of an additional heavy solenoid, additional foot or so of heavy AWG 2-4 wire, additional panel switch and wiring against the low chance you'll ever need it. -Kent Cozy IV ________________________________ Message 4 _____________________________________ Time: 08:00:51 AM PST US From: "Robert L.

Draw wiring diagrams to figure out what needs to go where and then talk to your local technical counsellor to understand how it all wires together. Reading Bob's book (the Aeroelectric Connection) is also one of the best ways to better understand the 'Greek'. Start radios, leave the Dynon till later, and begin with the power and grounds. Figure out the current draw and the size of the fuses. Ask yourself the following questions, and keep asking until you have figured out what is required to provide all the functions you plan to use. Identify the pin number on the connector of the source device and where that signal will go to on the receiving box (connector and pin number). How will you provide the altitude information to the KT76A? Do you have an encoder or do you plan to use the Dynon? Do you plan to use the VOR in the KX155? Besides the KX155 what audio inputs do you plan to the intercom? What are you doing for a GPS? Does the EFIS need a GPS input? We were all a beginner at one point, this stuff is not intuitive to most, you haven't bitten off more than you can chew - just take it one bite at a time.

PSE once had a .ppt on their website depicting how to build that harness. I notice they took it down and I know they won't warrant their panels unless a harness is purchased from a dealer. I have a copy of that ppt if needed. Bob's cartoons showing how to treat the shields and daisy chain them is good info for you, and you need to understand shields are not used for anything but shields, so no audio on them and they ground at one end only to prevent ground loops. The other thing you'll run into is differing terminology between the various brands, especially "audio low" . The Dynon is pretty much self contained with no remote magnetometers or AHRS units, so that simplifies things also. You'll have to plow through each install manual several times and make some inquiries when you can't figure it out, but it's all there. I have my schematic for a 5000EX to Garmin stack, if you would like a copy it may get you started in designing yours. Or maybe someone has the same equipment as you and can supply a drawing. One tip on the audio harness, since all the shields terminate at the audio panel, you'll have to terminate those to wire and then D-sub pins per Bob's pics or the .ppt. There may be too many to get them into the connector shells so you may want to make those terminations a bit longer so all the splices can be just outside the shell. Pm if interested in the drawings or ppt. Tim > On Jul 13, 2014, at 2:36 PM, Peter Pengilly wrote: > > > Jim, > > To connect your equipment just take it one step at a time.

I bought a plane with an EPI-800 installed, but most of the installation manual was lost. I'm particularly interested in the wiring associated with the backlighting system. At present, the backlighting doesn't work at all. It's supposed to sense the voltage on the lighting bus. My plane has no lighting bus, and the builder disconnected the lighting wiring for the VOR head and the transpondes, so I assume he disconnected wiring for the EPI-800 as well. ________________________________ Message 15 ____________________________________ Time: 07:11:16 PM PST US Subject: AeroElectric-List: Re: Dual master solenoids From: "user9253" > I'm not excited about the use of his "always hot" main bus because of the additional wire runs it would create from the buss mounted close to the rear mounted battery and difficulty accessing fuses for those wires. > I'd like to run all electrical busses from the always hot side of the starter solenoid (always hot when master solenoid is hot). Schematics do not indicate how wires are routed in an aircraft. They show the logic of a circuit, not necessarily the physical layout. The heavy wire that supplies power to the main power distribution bus can be connected to either end of the wire between the two contactors (main battery and start). Your idea of connecting to the always hot side of the starter contactor is identical (electrically speaking) to Bob's schematic. > I was thinking that a second master solenoid, with a separate wire and switch, wired in parallel at the battery, would address this issue. Like Bob said, the E-bus circuit addresses this issue. If you would rather backup the main battery contactor, it can be done with an automotive 30 or 40 amp relay at a fraction of the weight. The relay must be disabled during engine cranking, maybe like the attached circuit. But keep in mind that the more complicated and the more components , the more to go wrong.

I'm surprised about 'heat issues' . . . these things draw about 3-5 watts in operation, the vast majority of which gets turned into heat. Unless there are items with localized heat-dissipation issues (doubtful for a hand-held device), I would not expect there to be any problems for operational heating. My experience with the Ipad is similar to Tim Andres'. I set it in my lap (out of its case) and unless I have a fresh air vent directly blowing on the device it will shut down with an over temp announcement within 30 minutes of operation. My IT friend believes the Blue Tooth communication with the Stratus ADS-B receiver creates a larger drain than the Ipad would normally produce. I fly with another older handheld moving map as backup. The Foreflght + Stratus has tremendous capability when it's working but I don't trust it as a sole nav source. Reliability needs improvement.
