You're killing me... I appreciate you showing me the colors connected together, BUT what is relevant is where do those wires go?
I think I've found the problem. It worked perfectly by bypassing the harness. Connected everything back together except the black wire that was connected straight to battery +, and it still working. Now the charge is 14.5 at any rmp.
Now I just gonna trace the black wire and find where the issue is..
So in this example, you prove my point exactly. By disconnecting BLACK the R/R is throwing maximum charge at your battery without constraint. Your alternator can produce up to 18v, and this will fry your battery immediately.
Show me pictures, or describe in detail, what wire color coming from the R/R is connected to where. Then I can help if you still need it.
Looking at the first pic, the bottom wires are R/R wires (mostly rectifier). You can also see also see White and Black wires, but not the Green (regulator).
Rectifier:
Yellows -> Yellows (Alternator)
Red -> Red/White (Starter solenoid)
Green ->Ground
Then second pic, regulator wires:
Black -> switched 12 volts
White-> White(alternator)
Green-> Ground.
Now by connecting the black from Regulator to battery +(bypassing the harness), it charges just fine.
The black wire starts from the ignition switch to front brake switch, starter switch, engine stop switch, winker relay, oil pressure light, neutral light, turn signal buzzer, horn, rear brake switch and then to the Regulator.
I am losing 1v from Ignition switch to the Regulator. All connector look good. I am just gonna tear apart all the switches and relays and see I end up.
Thanks again
