Matt. I should have posted this some time ago. A good friend had a V tail with very similar issues. He went through the wringer with the issue and $$$$. He actually sold the airplane. The new owner located the issue. In the V tail there are two major holes in the firewall for wiring and cables. In the penetration for most of the wiring to the front end, they found fatigue in several of the cables. The cables were either stretched or in some cases, casing rubbed through. The fix was to re-wire the entire front end back through the firewall. The exact culprit was never located but the plane flys well today without issue. Something to consider.
This is AWESOME! 1. I was at that Broncos game 2. You flew right over my house on approach to KAPA (live near the reservoir on your right shown at 9:08) 3. Eaten at The Perfect Landing several times. A schoolmate of my wife's family owns the restaurant. Thanks for showing my hood!
Intermittent problems are an absolute nightmare no matter how good someone is. They are very difficult to replicate. I hope it's figured out and taken care of finally. Thanks for bringing me along with ya Matt!
That really sounds like a bad ground. Especially since you have replaced the parts already. I would clean the spot where the ground goes to the frame, or maybe even replace wire. I think its intermittent because of aircraft vibration. i bet it always reads good while the plane is on the ground.
@@slaznum1 That's exactly what I posted on one of Matt's previous videos! I had a similar intermittent issue on a car, replaced lots of things, then after a strip down I discovered that the only engine earth strap was a ratty piece of wire! Replaced with a proper braided strap and it's been fine since.
Yeah, the plane is never actually on the ground as far as electrical grounds are concerned with those rubber tires ??, it sounds more like something is overheating, or overloading, a temp gun would be my suggestion or an infrared camera if you have access., just look for hot spots., even if it’s a poor ground connection it will create heat..
I'm a aircraft engineer and going by your maintenance history, wiring checks are the obvious thing to follow up, not throw parts at it. Every wire, every crimp and connector on the alternator circuit. I work on 787s plastic bastard and this is one of the first things that is required!
The flight legs were wonderfully familiar. A momentary loss of situational awareness occured when it appeared like Matt was suddenly alone in 7P. The journey became an exhilarating pondering environment between beating responses to atc and gazing out at many of the most scenic areas in this part of the USA. My mind swiftly analyzed and formed a diagnostic of the missing electrons. It was easy because I know that all of the charging system appliances function perfectly and that the electrical system components are functioning properly. EZPZ enjoyable ride along for me. Thanks. Also enjoyed reading comments about ground fault and or open connections. Which led me to my final conclusions. Yes! And beyond simple opens at ground paths I followed Inductive heating and high resistance in the components connectors wiring, switches, breakers or power relay switches at the accessories power circuit from switch to source. Kinda like a fully loaded bus bar extravaganza I thought. As the resistance slowly increases due to inductive heat two faults occur simultaneously. The secondary or conditional fault is because the voltage regulator senses voltage out of limit but the primary fault is high resistance at the weakest point in the circuit. It is not like water pressure and damns at all, no, it is akin to a good conductor who quits when under to much load. The liberal pertinent utilization of the Ohm meter and dc amp probe can quickly pinpoint diagnose the entire circuit and then divide it further until the point of failure is isolated. The electrical system schematic is as enjoyable to me as a VFR chart but clear and concisely configured like the IFR chart. Anyway, I wish all the rewards of experiencing at least one wiggle test. Cheers.
It always rains in the afternoon around Montrose. Doesn't last long but you can almost set your watch by it. And I agree on the ground being the problem
I can hear the song "Shaft" playing when I watch your tubes. Truly the coolest cat in the skies. You're also the king of snacks. Snacks and airplanes go together like magic.
Every time you bring up your alternator issues all I think of is that you have a ground problem in the system. Even if they use a normal multimeter and get conductivity, you may still not have a good ground. That is only detected by the use of a milliohm meter. We normally don't consider something properly grounded if it's over 2.5 mohms.
We camp there almost every spring. Years when the snow pack is good, there is a river running through the base of the dunes for a week or two. (Medano Creek) Also, an awesome short hike where you can stand inside a frozen or partially frozen waterfall (Zapata Falls) Hot springs nearby as well. And, to top it off, an alligator farm you can tour!
Hi Matt, it’s good to see you flying your plane again. I have an old 6 V car that is prone to corrosion in the ground to the engine. When the ground cable has internal corrosion that you can not see, the resistance will test good with the ohmmeter when not running. As soon as the engine is running you can get an intermittent open in the circuit. 24 V electrical systems are less prone to this type of problem than 6 V. I suspect this may be what is causing your problem. It is cheaper to replace ground wires than alternators. Do you have a backup alternator? Keep up the good work on producing your great videos. I especially enjoy the mountain flying ones. Have you considered getting a portable oxygen system? I find that it gives me much more flexibility flying in the mountains. Once again I love your videos. Keep them coming.
If theres a dead spot on the alternator it can act like your describing, intermittent but operable. I've also had an alternator snap off their positive connection and vibrate loose from the negative internal mount as well. Both conditions while not the same will exhibit intermittent failure. I've found heat shrinking both sides of contacts effective assurance of continuous service assuming normal conditions.
Make sure goofy things like "digital ground" and "analog ground" are separate and each connected solidly to chassis ground. Could be something goofy like vibration shorting out a loose connection. Good luck.
KAPA is probably one of the best spots to watch military aircraft in Colorado. I think KAPA has a refueling contract with the military so we get a lot of fighter jets flying in. Mostly F-18s but sometimes we get some A-10s, F-16s, and F-15s.
My money is on a grounding issue. Intermittent issues are almost always a bad ground. I don't have an airplane but I have a race car. Had intermittent electrical issues. Kept replacing things. Checked ground connections. Nothing. Then a guy on my crew physical grabbed all the grounding straps and gave them a tug. One broke off in his hand. But it looked perfectly fine when checked. Replaced it, it was good as new and then went on to win a 25 hour race.
FYI, the Red Arrows are the British version of the Blue Angels. They have the best smoke show. Said by an American whose house the Blue Angels overflow ever year in the 1960s, and I love them, too.
FYI the Red Arrows are the UK version of the Thunderbirds, since they are RAF. The Royal Navy display team, actually the Fleet Air Arm, uses helicopters, Gazelles I think.
@@cageordie Right you are. I stand corrected on the letter of the thing. However, since the Blue Angels were the first and remain the premier team, as an American, I look at the Blue Angels as the apropos comparison to the Red Arrows. I don't know whether Matt was thinking of the Red Arrows when he misspoke "Red..." when he meant to say Blue Angels, and then corrected himself, but I would think that is highly likely. Which once again speaks to my point of the appropriateness of the comparison. Anyway, thanks for the reply. There's a great Red Arrows video from the 1980s which introduced me to them back then. I remember being taken by the deadpan British version of the Chuck Yeager voice saying "Smoke on... Smoke!" and the amazing flying and smoke choreography. They were doing the Blue Angels one better back then as far as showmanship was concerned, to my eye. All the best.
@@aviation3530 You provided no actual facts in your video that Matt is involved, just assumptions. You also posted under my reply that has nothing to do with the ditching. Stick to flying not computers.
@Aviation +penguinatorfps : You are repeating and believing(?) the unproven accusations of an old grumpy man, trying to increase his popularity and youtube numbers by uttering pure, unproven assumptions ! You should stop doing that and simply shut up, because this legally is calumny !
We all anxiously await the fix. A question. Are you allowed to fly into San Diego International airport? That airport has the most incredible approaches, almost always via a different route, sometimes seemingly wheels touching rooftops, that I have experienced on commercial passenger flights. I would love to see a video of you navigating in and out of SAN.
As I wrote before I think you should write a book about the airport restaurants you visit. You could give them some kind of rating on the decor and the food and service plus anything else. You might sell a few and make a little $. One more thing , I wish you could turn down your cockpit speakers a little so we could hear you better. Love your vidios by the way especilly the scenery shots.
Mosca pass and the Great Sand Dunes is my back yard. Based a few miles north of there. Plus you are going to see my buddies at HP. I am flying a tail wheel with Bill O this Wed-Fri
Lets hope you can get that charging problem fixed. As an automotive tech I can say it's not easy troubleshooting intermittent faults, especially electrical.
My 2001 dodge ram 1500 5.2 is having on occasion a high voltage situation but goes normal on idle and then just goes away completely for a few months or three?
Welcome to Colorado. Taaa-oos, NM (not Tah-os). KAPA is my home airport. You can also land at KFTG, closer for you GF to get to DEN, it’s towered and not busy, but very close to DEN Bravo.
Did I read that correctly at the beginning of this vLog it was filmed in 2018???? Loved the landing track......I've used that tune on my channel ;-).......It's just not nearly as popular as yours though bro!!........Question, what are your night settings on your GoPro's that footage was really nice!
Amazing ATC got on that guy's case at 23:25 for just asking Matt a question. The ATC was dead silent with nobody else on there yet he did that and his constant insistence to avoid the restricted areas.
Dumb question - does your plane have a second alternator? If not, what do you use to back up your panel displays? Also, did you have to get a ferry permit for your flight? Assuming alternator is on MEL.
There is a wire or connection that is compromised. Such as a wire with damage insulation, because it’s rubbing on a metal edge. Or a connection at a connector or terminal lug that has corroded.
MATT I'M CURIOUS WHAT YOUR ALTERNATOR CHARGING ISSUE IS, PLEASE LET US KNOW, I'M AN A& P MECHANIC, QUESTION HAVE YOU HAD A CHECK FOR VIBRATION OF YOUR PROPELLER, THAT ALTERNATOR IS RIGHT UP FRONT, IF VIBRATIONAL FREQUENCY ENERGY CAN DESTROY THE BRUSHES IN THE ALTERNATOR, LOVE YOUR CHANNEL,
Hello Matt and Rachel from Sydney Australia. I wonder why the alternator in the Bonanza is sporadic in function? I am diagnosing; when you reduce Electrical draw from flowing current it resets something? JET TIME Did you log any hours flying in that citation? Peace be with you, happy easter 🥚🐣🐥
