I tried jumping my 91 civic lx and when I attached the jumper cables there was a loud pop and sparks. I had no power to either my headlamps or door locks I'm thinking it's the fuses but I don't know which one/s!! Id be most appreciative for the help thanks!

Here's how to properly test all under-hood and under-dash fuses:
