1970 Chevelle 396 HEI Ignition No Spark

Another quick question. I pulled this picture from another forum post online, it is not mine. Ignore the red circle. Is there a possibility that this is a fuse issue? If it is a possibility, which fuse should I look to change? Is there a way to test if the fuse is bad? I am familiar with fuses for newer cars and how to see if they've gone bad but I've never dealt with fuses like these. Thanks guys!
