I have a 2000 Civic LX. I have been replacing the bumper cover, bumper reinforcement and headlights from a previous owner.

I removed the battery to let it charge. When I went to place the battery back in the car, it blew the 80A fuse under the hood. It happens each time I try to connect the negative cable to battery. I have checked the ground from the trans to the body and from the battery to the body. I have cleaned both, but I'm at a loss as to what to do now.

Any ideas?

Could a bad battery but the problem? I've never had this issue before on any vehicle.

 

Are you installing the battery backwards --> + to -?

 

no...not according to the terminal posts on the battery and the clamps on the cables. I may go buy a new battery to see if that was the issue. I know some people state it's the alternator, but that shouldn't be it, since I don't even get to make it that far in the ignition process.

I can't even hook it up w/o blowing the fuse. It's weird that it just started happening. I've replaced the battery before and never had this issue.
