Were you tying to charge a near-dead or dead battery with the 200A alternator? Of course the fuse will blow...try a circuit breaker instead, it may be more tolerant of the initial surge. Otherwise, trickle charge the battery back to life, and don't let it go dead again. Do not put a larger fuse or breaker in than the wire is rated for at the length of the run.

Otherwise you have a dead short to ground on the fused wire, or are wired wrong.
