Hi

It's not "also", it's the only function of the ballast resistance.

It might be the only function of it, but it is accomplishing this task by adding a resistor in series with the coil, hence playing with the Voltage over the coil.

School? Hope you didn't pay for that course.

ACME type schools don't exist over here, only real once.

How's that English course working out?

 

Probably, his English is better than your German....

 

Absolutely,
Therefore, I would not argue about German with a German lingiuist, just as I would not CLAIM to know more about function of resistors in a circuit than an EE.
I do, however, tire of the modern day PC trend.

 

Okay, regarding the blue highlighted sentence above, let's do a simple math/ignition circuit quiz. Let's say you have a 2 ohm ballast resistance, and a typical 8 mH coil with a 1 ohm winding resistance. To make the math easy, assume the system voltage and battery is an even 12 volts. The moment the points close (start of dwell), what is the voltage across the ballast resistance, and the voltage across the coil?

Gunther only, please. Others may PM me with their answer.

 

Eh, why is everyone trouble shooting the PI when you describe the distributor as being excessively worn? Could that be the problem? Why not replace the disti and see how that works out? I have a PI in my 69 Mustang that's been there for eleven years, hooked to the hot side of the coil. It runs great. My son's 69 Mustang, with a sloppy, worn disti, has had it's PI for sixteen years hooked directly to the + side of the coil. That car still starts and runs great too. I intend to install a PI in my 427/390 69 Vette. It appears that the PI II is more frequently the culprit in failure scenarios. Which one does your car have?

 

Hello again.

Therefore, I would not argue about German with a German lingiuist, just as I would not CLAIM to know more about function of resistors in a circuit than an EE.

Dear FB007

You must be a big believer if I interpret your sentence correctly. May be that's why your previous President had such a easy game making you believe that the world is safer now .

Also ,am I too stupid to understand what a language has to do with technical matters ?

Dear 69427

I apologize having argued with you. I will not try this again. Your body guard ( see above bolted text ) has made it very clear to me that I should not argue with a EE, sorry.

I would have loved to understand why the Voltage does not drop at individual resistors in a series system , but like I wrote, you must be right .

Hello everybody

OK, I checked the instruction sheet of my Pertronix ignitor 1181 ( is this the ignitor 1 ? ). It specifically states not to remove the resistor .
The red wire of the ignitor is connected to car Voltage before the resistor and the black wire to minus, so the ignitor itself gets unresisted Voltage ( sorry , current ). The coil stays connected to resisted Vo...Current .

In the troubleshooting steps, there is a item called: How can I fix a low voltage problem ? The fix is to assure the red wire of the ignitor is connected prior the ballast resistor.

Wish they wouldn't speak about Voltage, but current.

But it seems to make more sense when explaining it the Voltage way.

Spelling mistakes and grammatical errors can be kept by the finder.

 

I am no ones bodyguard. Merely a seeker of truith. I just don't care for BS in any language. The fact that your long answer circumvents the question presented provides the real answer as to whom KNOWS what they speak of.
I would, however, like to present you with our ex-president as a gift. Every village should have their own idiot.

 

I still invite you to respond to my simple quiz in the earlier post.

 

 

Hello

Dear 69427

I am really sorry that you take my meaning about the previous presidential actions so personal.
Pls don't do this, this is just my point of view of it, probably as wrong as my Voltage story. I do apologize having brought this off topic into this technical thread.

And sorry, but I will not under no circumstances answer any questionary nor ask any more about this, this mainly because I feel offended by 3rd party gentlemen who are pulling my leg.

By the way, I am not German , but speak and write German nearly perfect. ( beside a couple of other languages including my mother language ) & as you know, pretty imperfect English which I am really sorry about.

I would pay you a beer, but the chances that we meet are minor.

Rgds. Günther

 

Unfortunate timing for the beer offer. I've been to Luxembourg several times, doing work at my employer's technical center in Bascharage (I hope I spelled it correctly). But, I don't get over there very often anymore. You have a beautiful country, and as I believe I have said before, I'm extremely grateful for the great care that your countrymen have shown on the upkeep of the US military cemetery there. Those of us who love this country, and respect those who have defended her, appreciate the respect your people have shown our soldiers who are buried there.
Thank you.

 

Hi

I think I know your technical center in Bascharage.
If it has something to do with car industry, then I understand that they have rather big problems as well caused by the recession.
So the chances to meet over here are probably even less now.

You seem to have a very clear political direction. Seems difficult to argue about with you. Let's see what the future brings.

Rgds. Günther

 

Yes...some folks only care about their point of view and never even listen to that of another. They know they're "right" about everything and could care less about how their intolerance impacts others. Sadly, to them everything is an arguement; the idea of a discussion is totally out of the question.

 

Then I solicite your advice. How do you handle the correction of BS that abounds here while not offending anyone involved?
There was a real oppertunity to clarify some myths here, yet it turned into world politics.

 

Could you be a bit more specific to whom you're referring?

 

I'm not arguing. I'm merely expressing my displeasure that you insulted my former president, and also those of us who supported him in his fight against Islamo-fascism. Given your country's experience dealing with the *****, I would have assumed you would have an appreciation for the fight against ideological extremists.

 

First of all, what others have claimed about the GM points-type ignition system is not all BS. If you really want to understand this type of system, you might want to read the content of the following site:

http://autorepair.about.com/cs/gener.../aa052502a.htm

It gives a good overview of this type ignition system. The section titled "Ballast Resistor" may hold some interest for you. It explains its purpose and its operation. Note the part about the voltage with the engine "running"; that may explain the reduced voltage which you so adamantly deny. Perhaps the voltage on a 'running' engine might be different than for a steady-state condition with no current flowing.

I'm pleased that you were willing to ask for additional information. I hope that you find it useful.

 

I didn't get an answer to my earlier question regarding who your earlier comments were directed at.

Regarding your link, it was a very well written article, with the exception of the ballast resistor paragraph. I doubt you'll find any electrical engineers who would agree with several parts of his description there. In his defense, he did have to water it down for the shadetree mechanic crowd. (Ref: auto repair and general info.) An engineering textbook would describe that part of the circuit very differently.
And, for the 14th time, a resistor is not a voltage regulator. It is a current limiter. It limits the maximum coil current, it does not mystically create some voltage realm for the coil to exist in. In a points system, the coil (an inductor) is being fed by a 12 volt source, through a resistance, and all controlled in a PWM mode with a duty cycle of 67% (30*/45*). This is very different than a couple resistors being fed from a mystical 8 volt source, as some persist in claiming.
Just for kicks, as Gunther has declined to answer my earlier quiz, would you like to give it a try? After all, you are claiming expertise on this subject.

 

The BEST part of that article is where the author admits to being a "mechanic". Clearly, the man is NOT qualified to expain the system correctly.
