Tim, to clarify… to test the secondary winding with an ohm meter, connect the meter leads to the ends of the spark plug wires. You should read somewhere like 4 to 7 K ohms.
If you get an infinite ( open) reading the secondary winding has a open, broken wire and is most likely bad…. however, I have seen coils that test open produce a spark. The question is for just how long they will continue to run. There should be no connection between either spark plug leads and any ground.
