How about 6 volts? How about 3 volts? How about 1 volt? Sorry - but, for a given coil, the energy that the ignition system can deliver (to the spar) is directly related to the voltage switched across the coil. At some point (as you drop the switched voltage applied to the coil), a threshold is reached below which no spark occurs (ionization potential across the spark plug gap is not reached), so reliability of firing under worst-case conditions is effected. You stated; " putting the ballast resistor in series with the coil primary is precisely intended to reduce the voltage." Arguing the other way serves what purpose? |
non-sequitur that you were talking about earlier (as in: has nothing to
do with my side of this conversation), so not sure why you bring it up.
I have been consistent. Your dishonesty (or mental state - like I said,
sometimes the two are intertwined as to be inseparable) is showing
again.

See, this is where I take issue with the terminology you and the rest of the gaggle insist on using. To quote you "it is an unavoidable result," [it] being the reduced voltage. What else could a ballast resistor connected in series with the ignition coil reduce? Yes - and perform the function of a voltage divider. You're catching on, even though you won't agree. Why would it "function" as a voltage divider when the intent and purpose of the ballast resistor is to limit current? |
"hidden" in his post (hint: it has something to do with Ohm's law and
some silly little mathematical relationship among current, voltage, and
resistance (or impedance)).

...None of you got it, and it's one of the oldest test procedures that has ever been applied to using a voltmeter to test a BATTERY. I see - so instead of making clear what you meant, you inentionally speak in ambiguities where the context of the discussion clearly means something else than that more obscure meaning that you had. Funny that you NOW claim context as your excuse. You care not when it serves your purpose that even though a voltage dividing circuit is not used contextually as a voltage dividing circuit but for the purpose of limiting current. |
weasel wording - seems to be your forte.
See again Ohm's law, resistance, voltage, current and the links that you
yourself posted about voltage dividers that explain things very well.
Since resistance is difficult to change on the fly with a coil, the
design exploits Ohm's law by adding a resistance to control applied
voltage, with the result that current is controlled. There's the
all-truth of the situation.

Each battery is a series circuit. Do you know the difference between a cell and a battery? Guess not. Some instructor you must have made. |
go from either post to anything other than the end cell you are
testing a battery of cells.

However, as Bill has stated so clearly, you are a dishonest character, and are changing the question and the rules in mid-stroke. Nope, I clearly laid out the conditions to which you claimed I was wrong about. The whole thing proved that you can't make up your mind which raises serious doubt about -your- ability to apply reason and logic. Second - MOST batteries today do NOT have removeable caps. Hogwash. Exide batteries have removable caps, Interstate batteries have removable caps. About the only batteries out there that don't have removable caps are Delco/Delphi "Freedom" type batteries and Optima batteries. Thirdly, the ONLY definitive test for batteries today is a transconductance tester, such as a Midtronics. Red Herring, and besides, you don't even own a Midtronics tester. I have access to the shop Midtronics any time I want. Most Canadians |
results of the Midtronics tester are accepted to declare one of their
batteries good or bad.

It will NEVER steer you wrong and can test a battery with as little as roughly 10% charge ACCURATELY and RELIABLY. The voltmeter test is neither accurate nor reliable, You used a Midtronics conductance battery tester back in the 60s and 70s did ya? Aren't those decades the premise for all the "I've got 40 years of experience" chest thumping that you did a few posts back? Secondly, how do you suppose battery re-manufacturers identify individual dead cells prior to their remanufacturing process? |
battery, mechanically checks it, and repairs as required.

although it is better than nothing, and properly used can sometimes determine where an open circuit or short exists in a battery. It can also very often show a battery to be in excellent condition when it is incabable of lighting an 1157 bulb. More weasel words. Now, If you connect a LOAD to the battery, and THEn do the test, you MAY get more meaningful results - but then again, that was NOT the situation you described (or didn't describe. Well, you guys are so smart, I shouldn't have had to spell it out totally for you. Fact is, all I said was "connect a voltmeter to a battery." Your eagerness to jump to conclusions is what tripped you up. |
difference between a battery a cell.

| Admit it young feller - you are out of your depth, and as Bill has alluded, you'd swim better with both hands. "Young feller" Gee Clare, that sounds like it comes from someone who would have intimate familiarity with the type of battery testers used 30-40 years ago, you know, the big clunky hand held voltmeter with a ground lead and the test probe sticking out the bottom. Congratulations, you now know what that mysterious thing-a-ma- bob was used for. How about the cell load tester that dug through the tar-top battery |
the "definitive" battery tested before the Midtronics came along - and
before the hard-top batttery.

Right... I've stood outside in 28* below zero weather with a windchill colder than minus 100* watching Milwaukee firemen try to put out a fire where the water froze as it came out of the fire hose nozzle. I've been in ice storms that killed the power for over two weeks. I've walked out on the ice when Lake Michigan froze solid. I've jumped the ice heaves on Lake Winnebago many times in an automobile. |
And you even....walked out on the ice!
