Fusable link questions

sorry i was out sweating it out in miami i checked out bulkhead connector cleaned connetions replaced fuseable link replaced blue field wire at the split conn. back to the plug on right side alt. harness fuseable link still gets hot [real hot] i traced harness back from inside bulk head in through the dash to fuse box nothing seems to be broken cracked or worn. could the ign.key switch have something to do with this? the key works sometimes but most of the time it just studders like a dead battery batt. is strong, when i jump start relay it starts this is the 2 new relay any thoughts before i set this thing on fire!! [beside a fire extinguisher]this car has that stupid seatbelt interlock system i replaced the seats in this car from bench to buckets [not stock] light comes on in dash i placed a jump wire in the center seat belt connection but light still stay on does this help
