for small resistances, I have much better test/measurement results by applying a measured current (1 amp is good) and then using a different than ammeter (leaving ammeter in circuit so as not to disturb measured current) to measure coil primary voltage and calculate resistance with V/I.
Imgur is not permitting uploads, so I will send you a buzzer/relay circuit that can be used to make the coil spark at relatively high rate, via e-mail.
