Alt Fuse keeps blowing, Alt fuse issues Options

[rl2122]

Hi guys, Im new to this site. Anyways I have a issue with my 95 GT Celica. I parked it about 2 months ago and everything was fine. I drove it into the garage after a long drive but my plates expired so it sat for 2 months. Unfortunately the battery died and now that im trying to get it back on the road im having issues. I'll try to make the story short, I put in a charged battery and nothing. It will turn over but no start and no dash lights or anything electrical. I checked my fuses and the injector fuse was blown and also the 100 amp alt fuse. I replaced both, but once I connect the charged battery they blow again. I went and bought another alt fuse. I pulled all non essential fuses this time before I connected the battery but once I did it blew again. Im just baffled since it was just fine before I parked it. Any suggestions???
