Nissan Repair: 140 Amp Battery Fuse, amp fuse, fuse block

Question
On my 1998 Maxima, I just replaced the battery (car wouldn't stay running when jumped), started fine the first time. But the second time nothing. Looked at fuse block and there was a 140 Amp fuse marked battery that was blown. Id this my problem or is there something else? Where do you find a replacement fuse?

Answer
Eric,

If the master fuse blew due to a low battery no problem.  Replace it and you should be fine.  If it blows again you need to look for something major that is pulling a load like a defective starter or alternator or even a wire shorted to ground.
