Sound dyinosis

[Helirich]

So I'm barely hearing a sound that I courious about. The sound is kind of like a faint tambourine every two seconds. I might say it was a speedometer cable, but it appears to go down with engine speed rather than car speed. If I was to guess, I would say it was coming from the fuse/relay area or the electrical box behind the driver's seat.

It is so faint that I can't say if I'm imagining it. Anybody else had this issue?

Have you tried adding more cowbell?

You can do better than that. Micheal is going to rock on this. Maybe "turn down the Fleetwood Mac" or some such.

Instead of posting another useless thread, why not take a video while the sound is occurring is upload it? This will actually allow folks to help you identify the issue

With his threads the word "useless" is a given.

[Ron]

My guess is a loose screw.

Because he doesn't actually want advice or help with anything. He just wants to hear his own voice. Wasn't there a thread titled something like "Would you risk it?" or some such, about ridiculous problems (a/c pressure switch or something)?

There are much larger issues here than mechanical/car issues.

So I guess your going to be one of these people that harasses others.

It might be useless to you, but I would like to know if it's an issue to worry about. Video of what? It's a sound. Could I record the sound? Maybe, but I seriously doubt it would be heard over background noise.

These cars have been around for long enough that everything has happened before. I was hoping that someone allready has heard it and might say "that's the frequency valve, I know it's hard to believe you can hear it inside the car". Or maybe they will say "it's just relays clicking".

WTF are you talking about? If someone said "your lambda unit is about to go, you need to check this", how is that not wanting advice or help? Hear my voice? This is print. How would I hear my voice?

On my trip, I consider AC very important in the dead of summer. Especially in a car that doesn't really have windows.

In closing, why don't you just not read my posts? It's really simple, read what you want and help if you want. But there's no need for negative comments. That just drives people to Fascist Book.

Michael, I will say that your posts are often funny. I don't mind that, but some are useless like this one. Pot calling the kettle black?

Nah man. Just an observation.

Yes, video a sound. If you can provide a video (obviously with audio) of the sound occurring, maybe it will pick up on the microphone? Maybe someone WILL say "oh its this or that". Going off a half-assed description that makes no sense is not enough to point to anything specific.

At least Michael has contributed to the community.

So you were basing your trip on the response of strangers telling you if you could hack it without A/C or not? And you were going to take that advice?

How come you claim you were willing to listen to that advice?

Ok. :rolleyes:

A negative observation. Have you never heard the saying "if you don't have something good to say, don't say it". I'll say this again, I don't really care if you want to harass me, I'm an adult and I have thick skin. But how about doing it via PM. When you harass anyone publicly, there are other people lurking that will not ask a question for fear of being ridiculed. That is not good for the forum/community.

As far as the sound, I don't think I can pick it up over background and besides, I'm not a computer wizard. The only video I've ever posted was many years ago. I used Utube. I won't use them again because they are part of a conspiracy to distroy our country. But, I will try to get a recording with my iPad and see if I can put it on here like a pic.

Indeed, Michael has contributed, not only to the community, but he has helped me in perticular. He does have a pointed sense of humor that sometimes doesn't come across well. I except that. Maybe I don't come across well. I can except that also, but you will never find me harassing someone "out of the gate". I might give a stinging reply, but I'm not first.

I take offense to the insinuation that I haven't contributed to this community. I have written several "how to's" been thanked many times. I've also had people tell me in a PM that I shouldn't get disgusted with this forum because of a few bad apples. That tells me there are people afraid to post for fear of "the mob". Do you want this forum to be a dozen people? Do you want this forum to close and move to Fascist Book?

Actually, that was not the question. I knew I was not going without AC. I believe I was asking about running the AC without a low pressure switch. (Bypassed) I believe someone suggested I gut the shrader and install an elbow shrader. I took that advice and it worked. In fact, it is still working.

As I recall, I was also questioning driving long distance with a broken manifold stud. (Not leaking yet) I think the consensus was go for it. I would have, except I was able to remove that one stud and replace it without removing the manifold because it was in an easy location.

I think Helirich is a good guy. He seems fairly competent in the wrench turning department, wants to be a positive part of the community, and tries(keyword tries) to be helpful and from what I can tell, has been nothing but respectful to everyone here even when we are less than. I have a neighbor that he reminds me of, very outspoken, loud, abrasive, thinks he is always right and freaking thinks he knows everything about everything...he was one step away from being homeless till he hooked up with the widow that lives near me. Thing is he is a really nice guy, and very personable most times...and I think he is a very honorable man. I'm not his biggest fan though.

Personalities don't always sync up, especially on the internets when inflection and tone are missing from posts. I know people take me too seriously. To paraphrase Eugene levy, "You think you hate me now, but wait till you meet me."

I try to overlook such things because I just bet if we were all in the same room together, we would be all friendly and cutting up with each other.

As far as the problem, I think Ron was close. It's a loose nut in the car...probably operator problems though.

Seriously though, make sure the sound is not coming through your speakers. Sometimes alternators can give feedback through the stereo.

[Bitsyncmaster]

Electronics that use a switching circuit can cause an audio noise if driving a magnetic load (transformer, etc). The Lambda drives the FV and the idle ECU drives the idle motor which we know make noise. My fuel gauge ECU can make a little noise but you won't hear it with the engine running.

If you have an amplifier for your audio system it could use a switching power supply. High power LED headlights are another system using switching regulators.

On the first note, I hope it's true because we need each other. There are political types that would be just as happy to make a law that only cars newer than 20 years be aloud on the road. Of course, the vast majority of people don't drive old cars and would stand idly by while they take our freedom.

On the second point, would the speakers make noise when the stereo is off? I've had a strobe light on a aircraft make noise in my headsets, but only when the avionics was on.

I will show my ignorance here. Where is the idle motor? I just went through the DMC parts pages and can't find any reference to it. When you say it makes noise, where and what kind? I know I read that your idle controller shuts down the idle motor at high rpms. I wonder if that's my fix. Actually, is there anything wrong with an idle motor that is making noise?

My stereo is stock, but I suppose there is an amplifier inside the Craig. Again, it was off.

[Bitsyncmaster]

Idle motor is an electrical valve that is driven by the idle ECU which opens and closes to maintain a fixed idle RPM. It's mounted on the drivers side valve cover and has a 3 pin electrical connector on top. It will always produce a buzzing sound when the ignition key is on with the stock idle ECU. That is a 100 Hz frequency.

Ok, that seems to be an unlikely source for this sound. It sounds like a slow beat. Maybe every second or two. It got slower when I shifted from fourth to fifth.

Since it is RPM related, you might try switching the engine off and and see what you hear while it is coasting.

Also, you've made at least two OT political comments in this thread so far -- Three strikes (anywhere) and you are out. Same if you start an argument/discussion about it. Just stop now.
