Starter Switch Test

[joltesvig]

The starter key switch has armor all the way into the bottom of the distributor. I already replaced the spark coil with a new one. Still have no spark so I think the starter key switch has gone bad. Before going to all the trouble of replacing the key switch, I want to test it but the armor prevents me from doing a continuity test as far as I can tell. Is there an easy way to do a continuity test on the starter key switch?
