Measuring of plugs was fine. I verified all by measuring multiple times, installing plugs into the caps, installing caps on wires and testing overall. 2 with no resistance, one with over 40K where my meter stopped, one with no continuity. Results were the same.
I don't have my usual multimeter where I am, this one is autoranging. This is why I checked the a set of resistor plugs to see results, which worked at ~4.5k ohms.
Results of primary coils though, 0 ohms, just showing continuity. The plugs I can deal with. My concern is showing 0 resistance (on this multimeter) on the primary coil, on both units.
