Grounding the triple tree
How is the best way to go about grounding the triple tree? I have a 12 Ultra Limited and my friend has a 14 Street Glide. I know I saw it in here somewhere but I cannot find it. Thanks!

Hmm I've been told to ground to the triple tree...
If it is true to the OP there is a screw and ground already there...just kinda got to look for it.

Provide a good amplifier ground. Ground cable should run directly to battery. Grounding an amp to motorcycle fairings or forks is insufficient due to higher current requirements of amplifier.

The longer the ground wire the greater risk you have of creating a ground loop which essentially an antenna for unwanted frequencies your electronics can pick up and give you a hiss or other unwanted sounds in your speakers. At least in amateur radio that's the rule. 3' of ground wore is all it takes sometimes. Probably not a factor with our bikes but just throwing it out there.

I agree go direct to battery but what your looking for on the neck is a tapped hole from the factory at the top. My bike never had a screw in it so you wouldn't see a screw. But if you use a mirror and look at the top neck you should see a factory tapped hole. I grounded my head unit to it but my amp goes all the way back to the battery.

You have to pull the ignition and small inner fairing trim panel to see/access it. Mine had a couple stock things grounded there. Pretty wimpy connection so I made sure it was grounded to the main frame by adding a heavy flexible cable to a screw I drilled and tapped a hole for behind the gooseneck. The main reason is because the triple tree isn't really connected to the frame if you think about the bearings and grease between them. I'm just picky too. Oh one more thing, IF you replace that screw in the triple tree with a new one thats longer to add a couple more grounds be sure there are NO threads coming through the bottom, maybe about an 1/8" will clear but NO more. I found out the hard way, i.e. turning the bars to full left it WILL bind inside the asssembly. I wasn't riding, Bike still on lift but could feel it very clearly. Could be bad news while making a U turn.
edit; My amp is grounded to the stud in front of the battery right on top of the battery ground cable, First one of many with all the lighting stuff,horns and fans
