get a 9 volt battery, 2 long pieces of wire, a clamp meter, and a volt meter.
connect one wire to the neg of the coil and the neg of the battery, connect the positive to the pos of the coil and pos of the battery, set the clamp meter to dc current, and the volt meter to dc volts. get the current off the clamp meter, we'll call it "I" and the volts from the volt meter, we'll call it "V". now divide V by I and youll get R or your resistance of the coils
or a quicker way would be get a dmm and set it to measure ohm and itll pop right up on the screen,
and there is no "typical" box rise
