I got the new alternator for the car and should have went in easy. Nope....everything was fine until we went to plug in the wires. Should have slid right in. They wouldn't. Can't get the wires to attatch at all. Also, the fusable link seems to have got hot and has melted together. Any comments or suggestions?? I am at a loss right now

well had to change the connectors and now it's up and running again and battery is all recharged...thank goodness
