Smoke!
I went to madelectrical not to long ago and did the wiring as it shows bypassing the amp meter. I also upgraded form pre 70 to 76 alternator and voltage regulator. The head lights stay bright all of the time now. I tell you after looking at the bulk head connector and seeing those small wires I'm glad I did what madelectrical showed. I can tell the difference in a healthy electrical system compared to what I used to have.
