Prop RZpm

[Robert]

When I pull at least 3g’s, the prop RPM displays jumps erratically turning red. As much as 11000 rpm.
Then as soon as normal 1g, everything thing normal.
Where is the wire lead or whatever that’s causing the behavior?

What’s R, T

Read...the....

Last letter is M, sometimes preceded by an F. They aren't trying to be difficult, but a whole lot of people come here asking about stuff that's already in the manual. It can tend to get a bit frustrating after a while.

Specifically in the Skyview Installation manual available free from this very website - section 7, pages 7-47 and going forward.

There are some people who must've been hall monitors during high school, and all these years later they can still *taste* the adrenaline rush that that gave them. You can spot 'em a mile away.

My goodness: @Rhino ! @airguy! @Marc_J._Zeitlin ! @swatson999 ! It's the Hall Monitors' Hall of Fame!

On one hand, y'all have a lot of knowledge, and it would be a shame to lose that. On the other hand, you're poisonous. On balance, this place would be better without you.

@Robert I see you joined years ago but haven't been posting that much. I'm new, bought a plane with a Skyview Classic system and I've been burning the candle on both ends ripping out the electrical system to redo it from scratch and to get the Dynon stuff repaired, rewired and updated to have it ready for when the engine gets back and we start the FWF stuff. The people at Dynon have been super helpful.

The mood here unfortunately isn't super helpful, as easy as Dynon says things are to install and configure, it isn't always the case and asking questions seems natural but there's a resident clique that doesn't understand the helpful nature of social media and they think this forum is their hang out. So, I apologize for them, they haven't been taught any different so it's the best they can do.

I'm guessing you didn't build the plane so the wiring is a mystery? Like Airguy said, there's an installation manual available here and the pages you'll want to start on are section 7 page 47. You'll want to read through that section and take a look at the wires that are designated for the tach signal. There will be two and, depending on the ignition system you've got, they'll either come from an electronic ignition module of some sort or from the magnetos. If I had to guess, those wires have poor connections and when you're pulling G's you're causing the connections to glitch.

Keep in mind, I'm not an expert, I'm spitballing a little bit in order to give you something to work with before someone else maybe kicks in another suggestion. Here's a link to where they keep the documentation

Dynon Avionics | SkyView Documentation

Dynon Avionics' User Guide and Installation Manuals.

dynonavionics.com

but this is the one you want

https://dynonavionics.com/includes/guides/skyview/SkyView_System_Installation_Guide-Rev_AT.pdf

If you haven't seen it before your head will spin the first few times you go looking stuff up but it's all in there and there are people here that will try to answer questions as the info in the manual doesn't always jump out and make itself clear to you even after giving it a few reads.

When you're ready to go look for stuff in the plane, if you haven't found it already, there will be a black rectangular box that says EMS-220 on it, it is the engine monitor module that collects info from the engine and sends it to your displays. There are three connectors going into it, the big one is the one with the tach sensor wires in it. GIve the manual a look, find the box in your plane, and see what you can figure out. I'll be curious to hear what you find.

This was helpful.

Ok - so just to be clear - first you take me (and others) to task for telling the OP to RTFM - and then you tell the OP to RTFM - but somehow we are the problem?

Got it...

if all you got was RTFM from my post then I understand better how social media might not be for you.

you guys create an environment where new people don't want to waste their time here then bitch how you have to answer the same questions over and over again. do you see the problem you've created there?

Fine. You're elected to solve all the problems, go be the hero. Enjoy.

I ended up here because the atmosphere in the Facebook group is toxic but I found the same thing here! If you're tired of answering the same questions over and over, stop being a d!ck to new people. @Robert came here to ask about his tachometer, if he didn't build his plane then it's months of reading trying to understand the network cables, the components, the pin-out for the 37 pin EMS connector, etc. He asked a simple question and over the course of five posts you did nothing but harrass the guy. Your post about the manual was minimally helpful but you knew that and left it at that anyway.

Healthy forums sites have a constant inflow of new people and those new people ask dumb questions but learn and eventually go on to answer dumb questions that the next wave of new people will ask. It happens, it's how the community stays healthy but along the way there will be a lot of valuable posts and helpful information. Dynon will benefit from a better vibe here and that's better for everyone in the long run.

Not trying to be a hero, just a forum owner who has seen this before.

Alright, I'll give you that - but a person who buys an aircraft and doesn't understand the way it operates, NEEDS to understand the way it operates. The only way to do that is to read the manuals for the installed equipment, and keep those manuals on hand for reference when a question comes up. An airplane is a piece of equipment that, quite literally, has the ability to kill you every single time you operate it. Not knowing is not acceptable.

So yes, I'll stand by my RTFM comment. It may just save somebodies life one day, and I'm good with that.

Maybe the problem isn't the fora. Maybe it's a "you" problem.

You joined 2 months ago, have less than 2 dozen posts (half of which are being antagonistic to other people here), and yet you seem to want to set yourself up as the forum police, and rudely at that, calling people "dicks". Again, I think I see the issue here.

To the real issue...it's not "months of reading trying to understand blah blah blah" to solve a problem such as the OP asked about. It might be a few hours to dive into the sections of the manuals related to RPM sense. Yes, over time, it will be many an evening reading through the manuals (you don't have to be an expert on every system to start flying, of course).

What do you want? People to give the same answer the manual has? Maybe we should just copy and paste the relevant sections in their entirety as the answer. He gave him the primary source related to the question. What more do you want?

There's dumb, and then there's just wanting to copy someone else's homework (to extend your metaphor).

My hero!

So -- do you guys have matching t-shirts and your own clubhouse 'n' stuff?

My impression is that this thread is not conducive to people wanting to buy Dynon equipment. It's Dynon's forum and if I were Dynon, I'd be having some offline conversations with some of the posters and I'd reach out to the OP in a more friendly manner.
Yes, I ran a very popular national forum for 25 years and have some experience in addressing threads that are not supportive of the company objectives. Private discussions were one of my tools. Getting the OP question addressed in a supportive manner was another tool. Explaining to people that a private (company) forum is not a "free speech" venue was a point that was not always easy to get across and was seldom appreciated, though true. Suggesting that people take a few days off could be helpful. Of course, none of this kind of advice is very often appreciated by people who have gotten their ego involved.
Yes, I reported it to Dynon for their attention.
I have gotten a lot of support from this forum and expect that it will continue to be useful.

it's come up in the forum I currently host; do we try to get official factory support or keep ourselves at arm's distance? I generally keep us at a slight distance so our membership knows we're not an official line of communication with the factory. If I were discussing this with Dynon I'd probably discourage them from even having this forum as their email support is really good and people coming here will think the replies will be as good and/or as fast which they haven't been. On the other hand, if the user base were as welcoming as Dynon would want them to be, it would have its place in the big scheme of things. Unfortunately, this thread shows how users won't always do what is best by Dynon.

nobody's arguing that but this thread was a question about a loose wire from an owner that seems to not have been the builder. in six type ratings I've never had to read avionics installation manuals so I don't hold the OP responsible for not knowing where the tach wires originate or terminate. more helpful replies could have pointed him in the right direction but your approach didn't do that.
