Damn Fuses

[Yamahauler]

i just resoldered my ignition. i put it back on, (there was no headlight installed). the electric start and neutral indicater both worked fine. then as soon as i plugged my headlight in, i switched the key on and nothing worked, starter, neutral idicater, or the headlight. I blew the fuse.
i didnt have a spare fuse there, so i pulled it to start it and the headlight and neutral indicater both worked. i drove it home.
today, i put a new fuse in, and as soon as i turned the key. damn fuse blew again.

please help me, what could this be?

sounds like your headlight is shorting out, Which is causing the fuse to blow
