I'm sorry, but I must return to a point regarding three coils. If the battery delivery is a constant at 6v, wouldn't simply adding a third coil of equal length and gauge as that of the first two simply disperse that same available 6v of current over three coils instead of two? Or will it rather suck power from the cells at a 3/2 rate as compared to at present? That is what I remain confused about. I know when one coil fails, the other does not get fired twice as intensely to compensate, but what does happen to that 6v of current, when there is only one coil to deliver it to? And what, likewise, would happen to that 6v current with a third coil rated at two ohms added? Will it increase the overall delivery of heat, or just disperse it like I was originally thinking? The reason it seems to stand to reason that the heat would be dispersed and not fire the coils as intensely, is because if I consider what would happen if I were to attach the SV evo to the LV 3.7v battery, I would imagine the result is that the higher resistance of the SV core prevents it from firing to full intensity, no? Wouldn't adding a third 2 ohm coil to a T1 core essentially be adding more resistance to the 6v of current? I suppose this would result in longer warm-up times, akin to the evo, which would in turn drain the batteries.
That aside, new core is in hand, and delivery sweet rips of mellow gold.
OK, where to start.....
Voltage is a
pressure, not a current. What the Europeans call 'tension' (we sometimes refer to 'high tension' lines, meaning high voltage, not that they are tighter than others).
Current is something different than pressure it's a more or less orderly
flow of electrons. Water systems are a good analogy. You have pressure difference (measured in pounds per square inch) and flow rates (in gallons per minute). Entirely different measures, done in different units but related. Higher pressure (voltage) gives us a higher flow rate (current). We could invent a unit to relate these two to each other, something in "gallons per minute divided pounds per square inch". Electricity is like that, that's what Ohm's law is all about.
It relates the pressure in Volts (a fundamental unit of measure actually, electromotive force is like length it's not derived from other units like most are). Current is an actual number of electrons (6 with 18 zeros in fact) past a point in a second, this is the Ampere. One Ohm will cause one Amp to flow when pushed by one Volt. The same load (one Ohm) will pass 2 Amps with two Volts and so on. Power, measured in Watts, is something else, it's Volts times Amps. So in the first case we have one Watt, but doubling the Voltage also doubled the current, now we have (2 X 2) four Watts.
Now to simple circuits. What we have is a parallel circuit. There is more than one possible path (two coils) for any individual electron to take, but it can only go through one or the other. Obvious (to us today) the current from the battery has to split at the junction into two groups of electrons (say left and right?) only to join up again on the other side. Like a river flowing around an island. This is clear to us, but it was profound enough for Norton to get his name in the textbooks for the next 400 years or so....
Your house is a parallel circuit too. Every time you plug something new in it too becomes a possible path for current (and therefore power use). Like everything else in the kitchen it's power use is added to the total. Your bill goes up accordingly. That's what happens if you add a third element to the two already there. Same voltage as before, half again more current now flowing through the new element. 50% increase in power all else being equal. So TV will no doubt cut the wire size in the coils down, increasing the resistance for the same length, decreasing the current therefore keeping the total the same (roughly five Amps for T1).
Or so.

I would be interested in purchasing a flashlight head for my TV if it was ever available.
So where/what then do I connect the probes to to test ohm ratings??
