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!

How in the heck would we know? You have the car. Have you thought about actually looking at the fuse box? Maybe testing the fuses with a test light? Come on guy, you're gonna have to have some skin in this game.
