My brother-in-law owns a '99 legacy wagon with just over 100k. Car ran like a top until a couple of days ago when the car itself started to turn over really slow when being started. His conclusion, the battery could use replacing, logical. So he purchased a new battery, problem solved?........NO!!!! Now he is having an issue with blowing the fusible link. Initially when he put the battery in all the dashboard lights, radio, etc worked, then he goes to turn the fan on and wham he blew the fuse. Any ideas? What size amp is the fusible link? I am assuming the link itself is the fuse, I have never had to deal with anything like this. Could the alternator be sending a bad current or something? Any thoughts or ideas would be appreciated.

 

Thanks

This may sound kind of stupid but are the cables connected to the right post on the battery?

The alternator may have a short inside it and the link does tie directly to it along with some other fused circuits. You could isolate the alternator leads and then see if the short is still present.

 

The link may be made for about 80 amps.
