I recently replaced the alternator on my 69 Fleetwood. When I removed the old alternator I thought I dummy proofed the process by labeling where the wires went. When I installed the new alternator I placed the wires back on the same terminals as they were on the old one (although the new alternator was slightly different than the original one). When I finished the install I attempted to hook the battery terminals back up, when I did this the cables started smoking and melted immediately. Can anyone give me some insight and let me know why this may have happened? Thanks in advance.

Re: 1969 472 alternator issues
What was different about the new alternator? I actually haven't heard of a faulty or shorted alternator causing battery cables to spark or melt. My first response would be to return it for another one. It's pretty hard to screw up that installation. I just hope it isn't a newer style internally regulated alternator; I don't know what that would do.
