Is it throwing low voltage codes?

Thanks for the reply, Baird. Yep, checked it with voltmeter at the battery. I also have a usb plug in that shows volts and it and my shop voltmeter show the same, but the factory volt gauge in the panel has always read 1.5 volts high, but I live knowing that.
Thanks again!

So it means IF the terminals are damaged.
I am getting only 12 ish volts at the battery until it is revved to 3,500 rpm. Stator does not smell burnt. Battery is one month old, same issue with old battery, terminals are clean. Since I am confident that I can disconnect the stator connector from the regulator, I will check the AC voltage and reply.
Thanks again for your help.

OK, as Max says, that is different...

There is a big difference between;

"THE RUBBER MOLDED VOLTAGE REGULATOR AND STATOR CONNECTORS ARE NOT SERVICEABLE. DAMAGE TO TERMINALS, MOLDING OR LOCKING LATCHES REQUIRES VOLTAGE REGULATOR AND OR STATOR REPLACEMENT",
and,
"my Harley service manual states that the regulator connectors are one time use only and once disconnected the regulator must be replaced."

They are fairly solid and sturdy connectors. Just use caution, and don't force anything. Make sure you can see/understand how the locking latches on the regulator work, so you can disable them properly, and you should be fine...
