That is about the worst wiring diagram I've ever seen, I'm not prepared to try and decode it. However... what is the circle with power and ground wired to it?
Note that any jumper that bypasses the ignition switch will be powering the regulator and possibly the ignition all the time. Either one, or both, will quickly drain the battery.
The battery "+" should connect to only three things - unfused to the rectifier output and the solenoid switch stud, and through a fuse to the ignition switch input. All loads (lighting, ignition, starter button) connect to switched power from the ignition switch. Generally with simplified custom wiring a simple SPST ignition keyswitch is used with only 2 connections - yours shows 3, I won't guess why.
