    It is charging now but it’s low voltage. Lingering around 12.5 volts. Should be around 14 I believe?

    14 is where it should be, but it might be 12.5 at idle. If you give it some throttle does it go up?

    And Just to confirm because obviously there's been missing info, this 12.5 you are measuring directly at the battery?

    1) What is battery voltage when bike is not running?
    2) what is battery voltage when bike is running at 2k RPM?

    After stopping and starting it several times it’s now charging st 12.3ish but when I shut it off the battery goes up to 12.5.

    12.3v is if you have it at 2k RPM?

    If that's the case then it's not charging at all, and it goes back up to 12.5 because you removed the load when it's running from lights, speedo, ignition, etc it's not much but would fit the bill.

    In that case you need to work your way back and find the VR wire to the battery and make sure your VR wire is hooked up Correctly to a breaker or a fuse (pics will help) and check that breaker or fuse isn't faulty then proceed back to your crimp job or could be rubbed elsewhere along the frame rail. The problem most likely lies in that line (and the wire from VR should be black with a fairly thick rubber coating)

    You appear to be receiving AC voltage out of the stator? If measured correctly based on above and chances are the VR wasn't faulty out of the box. So problem is in that line somewhere.

    Both have similar charging system don’t beat a good horse. Even in worst case it’s just faulty $80 VR since it seems the stator pushes good voltage 20+ in idle and 40-60 in higher voltage. What happens, or is it even possible to connect wires from stator to VR wrong way? Would it fuck all the electronics on the bike?

    All good advise^^

    Assuming you are getting ~20VAC out of stator

    Then there is an issue with one or more of the following
    1) There is an issue with VR
    2) The CB/fuse in the charge circuit
    3) Its wired incorrectly

    All relatively easy fixes. you should be on the road within an hour

    If you cut the wire between the reg and the battery, you have no choice but to replace the reg. If you splice that wire, you will have nothing but trouble.

    I’ve read it all several times.... just didn’t put 2 and 2 together. No one ever accused me of being smart

    New voltage regulator is on the way... now it’s giving me a hard time going into neutral...

    Still tough getting it in to neutral but the new voltage regulator brings the charging up to around 14.2... thanks guys!!!

    Haha, well you'll know for next time not to splice that wire!

    However, really splicing any wire on a motorcycle is just opening up a potential issue down the road. It's worth the time and money to just replace it entirely rather than dealing with it later when your probably on the road!
