Help, keep blowing fusible link

[siceng]

What will cause the fusible link 100a to blow all the time? I am doing a sr20 swap into my 95 240. What happeded was my brother blew the fusilble link by switching the + and - on the battery. I replaced it and The wierd part is that I can crank the motor and the fusible link won't blow up until when the motor is about to turn over then it blows. I know that there is a constant short to ground. At first I thought it would be the starter or the alternator wire but I totally isolated the short to chassis harness. I can't seem to figure it out after 3 weekends on it. If anybody has any suggestion please, please, please..... let me know.

Thanks,

disconnect your alt replace the fuse and start the car. if the fuse dont blow its your alternator feild windings probably melted and caused a short when the battery was connected improperly. you could have done damage to some other electronic parts by connecting the battery back wards.
