Alternator and Voltage Regulator Questions

I do have a manual... very helpful for sure. Thanks for that in depth explanation! That’s the sort of thing I need.

I’m planning on doing a mad-esque type upgrade. I see that the electrical experts here, you, crackedback, and slantsixdan, don’t entirely approve of it, but I haven’t been able to find out exactly why. I am going to run a new fused wire straight from the alternator to battery, but I still need to keep power to the welded splice. I don’t exactly like the idea of just looping it back to the starter switch, but I don’t know why that would be a bad idea. The main thing I guess is to keep the main charging circuit out of the dash.
