I brought it up because I did have a issue a while back with melting the blue wire in my harness on my other car not long after I put on a chrome Tuff stuff alternator. Not sure if that was what caused it to melt or not. I think that was a 75 amp IIRC.
Just read this.
If the blue wire got melted is because the alt was a dual field unit set up for a single field with a grounded brush and you connected a dual field setup on it, with the bad luck you connected the blue wire ( ign signal ) to the grounded brush. If the green wire was connected there nothing was melted but a full voltage output was obtained.
