STILL WILL NOT CHARGE

1974 Nissan 260Z

Electrical problem
1974 Nissan 260Z 6 cyl Two Wheel Drive Automatic

To any one I was checking the charging system on my 74 260z and I did noticed that it was very low on the charge at only 12.2v with all the loads and 13.7 with no loads, I decided to adjust the voltage regulator and got it to a steady 14.7. Al fine and cool but also I decided to install a rear defroster kit that I got from Jcwitney and used the original switch to complete the installation, I tested it and in the process did smell something like burning and noticed that my amp gage was not charging any more. Connected my fluk to find that the alt is not charging at all now. Tested all the fuses, fusible links, swapped some relays around but still no charge, was wandering what is the relation between the charging and the rear defroster, is there a component in common, One thing that I also do was to upgrade the charging system with a built in regulator alt did all the connections but still no charge, help!
wiring diagrams available?
