Rrrrrrr, need help on this one.

Welp, I have very good news and a little bad news. I removed bad horn relay, made no difference. To my surprise, a couple of you guys were right. I replaced the inline fuse with a fusible link and the power is holding up. Nothing is burnt, etc. Now, for some unknown reason, I lost spark to the plugs. I tried 2 different coils. Still no spark ?
