I have a 2000 civic si, and everytime I go to crank the car the alternator fuse blows. I have not had the alternator tested but would a bad alt make the fuse blow before the car was running. I turn the key and when I get to the last acc before the start the fuse blows. No work has been done to the cars electrical system. I am stumped. Does anyone have any ideas. Again this is the stock alt. So could a bad alt make a fuse blow, please I need some help. Thanks. By the way the battery is fine and the grounds are good.
