    First off, the set up as it is. I have over 100,000 miles experience running the otherwise stock set up with a 2.2 ohm coil. No problems. I have read that a lot of people run the 3 ohm HD coil with no problems.

    Now lets dual plug it. Two red 1.5 ohm 6 volt coils adds up to 3 ohms. Some say I need to run a booster and some don't. Some say they run two brown 1.5 ohm 12 volt coils without a booster with no problems.

    I am thinking I would be better off running two .7 ohm 12 volt coils without a booster than two 6 volt 1.5 ohm coils with a booster or without. Any opinions? But then there are those that claim running three ohms with a single HD coil is trouble free so why wouldn't running two coils at three ohms?

    And my still yet unanswered question: What is the difference between a 1.5 ohm 12volt coil and a 1.5 ohm 6 volt coil? Dyna won't answer that question. Any ideas. A friend thinks it is probably the winding's insulation value. Maybe it has something to do with the secondary windings? All my sources don't know. Even my dad! That's rare! I'll ask Dyna one more time.

    Well, I found someone that agrees with what I suspected. Rick says that the only difference that he knows of between a red and brown coil is the color. That make perfect sense to me. I am going to run two blue .7 ohm 12 volt coils wired in series of course without a booster unless someone has a better idea.

    The booster is only relevant to points systems. All it does is reduce consideralby the amount of amps through the points, thereby increasing their life substantially. Has nothing to do with electronic ignition machines.

    You should try really reading your gurus DT.

    A coil is ignorant of the voltage applied. There are a given number of primary windings seperated from a proportional number of secondary windings.

    A coils important spec is reisitance. Measuring the resistance of both types (12V & 6V) will support this. I would imagine there was a diffierence between to two at one time but no longer. Probably the ability to deal with heat.

    Surely someone will come along and dispute this.

    The insulation value as one of my friends suggested. Winding wire comes pre insulated in different amounts/types. Dipping them is just to keep the real insultion that is already on them from rubbing agin one another.

    Well the primary and secondary windings used to be separated by oil. Nowdays it's epoxy. The number of windings and diameter of the wire used determine resistance.

    My point is epoxy and the wire's insulation that is already on it in the spool before it even gets to the winding machine.

    Let's see, friend makes a comment, shortshaft likes it, dang, isn't science fun.

    Hey, limpshaft, when you get things together and ready for testing, get out your drug store peg hook multimeter and set it for volts. Put one probe in the spark plug cap. Hold the other hard to ground on the motor. Hit the starter. How many actual HT volts are you getting??

    Then take the ground probe and stick it up your ass. Now hit the starter. How many volts does the seat of your pants say. Just how accurate is that ass of yours compared to empirical smokethewires testing.

    This is some of the best entertainment I've had in quite a while. Bring it on bugshaft. Keep it going.

    And who might those be? Would you mind listing your references SS?

    Instead of retorts like these, let's be constructive and provide some meaningful advice. Ok?

    It's true that an airhead ICU is actually just an amplifier, so why add a second one?

    I have heard of adding a second BMW ICU when double plugging.

    Read the threads he started recently. He knows Oak and is happy to suggest he knows more and better. He keeps talking about how SnoBums site if full of errors, but refuses to give even one example of a typo.

    Throughout all his dribble, has yet to give a reference. He is too brilliant, beyond reference, a new age Einstein, just ask him.

    He is a self made man and worships his creator. Just a poser, "cause he can".

    Not mine WS, Dr. Taker's. So far he has referenced me to the bum, Oak, and Cutter. The Doc thinks he introduced them to me. :rofl And he sounds like he has never read them!

    Retorts! Have you been reading the CRAP Dr. Taker has been spewing my way!?! I guess all because he doesn't approve of one of my questions. I had the nerve to ask something that Snobum didn't cover! :rofl
    And some of what he did cover I disagree with. Oh the nerve! Me and a lot of other people. The spark plug cross reference charts don't even cover my question. It was as if I had looked at all that stuff before I asked the question. Oh the nerve! A question with an ungoogleable answer for christ sake! That make Mr T mad!

    Boosters? Chris Hodgson does. Rick at Motorrad electrktic does (did). They do (did) it so that the ICU and trigger would last longer for running a much higher primary resistance. Exactly why? I am not sure if they know themselves but it works. I have seen it.

    No, I am just a nobody that had the nerve to disagree with you and yours. I think the hurtful part is that it is for good reason.

    One typo? I gave an article as an example.

    By the way Dr. Touchy, I didn't say I knew Oak. I said I have met him several times and have known of him and been reading his articles since the seventies.

    So, explain what's wrong in the article?? Give us the corrections we need to worship at your temple.

    You've read Oak, congratulations, please give us something he's wrong about and give us your correction so we can worship at your temple.

    Tell us one thing you know about Airheads that the technical director for Butler and Smith doesn't know. Again, just one thing SPECIFIC. Did you send your data to Oak for review? I KNOW he's open to new knowledge and he also knows crap when he sees it, like me and many others.

    Hey, this isn't a good way to preserve interest in airheads. I look to you guys for info and knowledge, but when you start slinging shit like a bunch of monkeys, I loose interest. This thread had a question at the begining...SS did you even get an answer or an opinion? Grow up you guys, and teach us something besides the fact that everyone has an ego. I already knew that.

    You give this thread too much credit. It's just the internet. Airheads are Euro Harleys and aren't going anywhere.

    You guy's? I am not suggesting you stick things up your ass or any number of other rude suggestions from DT. I ignored it long enough and nobody said anything except for fishkens. ag, and WW. After all his name calling to boot I come back with a few myself and now it is "you guys"? I won't be swift boated. That's why I respond to that crap. I have wined numerous times about his behavior with no response so I fight crap with crap. DT has been on my back in a personal matter for a while now. I am not going to set there while he goes on and on and on with rude, personal comments. I have talked bikes with it no problem and have done so in the past but . . . . Here we are.

    Dyna emailed me again and really didn't answer my question specifically but did say that I was right in that there is no difference between the coils and that he wished Dyna would stop selling the coils under two different PN's in order to avoid confusion.

    Talking with a friend about it, he summed up my question in a very specific way. What is the secondary resistance? The primary is the same. The answer is in the secondary? Well, except for the insulation that WOULD answer my question! It seems to me like they are the same coil insulated well enough to handle 6 or 12 volts.

    I'm 3000 miles from home right now and don't have time to babysit the butt hurt. Chill or I'll ban all of you until I get home to sort it all out.

    I get less drama from my teenage niece.

    Thanks.
