Going by what you've said , I'd say setting the meter on the 20M scale, then taking the measurements between the terminals you've listed should yield the equivalent of an overlimit or infinity reading each time if the coil packs are good. My meter reads "OL" on the display for an infinity (infinite resistance) reading, but not all meters register the same, so yours may be different.

That's assuming that what the manual means when it's saying "Without 0 ohm or infinity maximum ohm" is that the reading should be infinity.
