I replaced my inner fairing and my handlebars and now nothing powers up only the lights turn on and nothing else. All buttons gauge lights horn etc don't work. Ive checked plugs and fuses good all grounds still connected. Any help thanks

 

Your post has very little detail so here are some general troubleshooting steps:

If your new handlebars rise 2+ inches higher then you should be using wire extensions. If this is the case and you did not use extensions the wires may now be too tight and have pulled apart. If you did use wire extensions then maybe the wires are out of sequence or if you did not use solder and shrink sleeves they may have also pulled apart or have a poor connection.

The wire harnesses from both sides of the handlebars have similar connectors. Make sure they are not swapped.

Double check all your connections. Connectors may look as if they're plugged in all the way but you have to make sure they clicked into place or they will pull out.
