Thanks all. There was a nice post of someone grounding the triple tree to the frame thereby making a nice ground that could be used for the amp avoiding the long ground cable and solving the problem of the poor triple tree ground that RF was trying to solve by suggesting the ground wire be run all the way to the battery. This solution provides proper ground and no ground loops.

I wouldn't splice the ground unless absolutely necessary. Run a solid wire from amp to ground.

Yes it does and the pre-rushmores to the Triple trees. It also come with 14g and 12g ground and power where as most other amps require no less than 8g. It goes back to current and resistance. That amp has a minimal power draw. There are quite a few post here from guys that have had popping issues, or some type of gremlin in their system and the recommendation from BT has been to try grounding to the battery.

Wouldn't be splicing the ground. The Amp would be grounded to the triple tree. The triple tree would have its own ground wire grounding it to the frame - essentially making it a proper ground. Stock the triple tree is not a proper ground - even though the stereo etc. is grounded there. Just fixing the real problem which is that the triple tree is not a proper ground.

Got ya, I grounded it as instructed and will keep that in mind if strange things start happening. Only have about 150 miles on the new amp, luckily no problems heard yet. I was out on the bike yesterday running errands all day, 71 degrees and lots of sun. Woke up to a blizzard, 8-12 inches of snow expected and more predicted for the end of the week and more next week. Gotta love the first week of spring👎

This is the way I ended up doing it. I grounded to the point on the triple tree and then ran a short ground jumper to the frame.
Bates - I realized the wires from the amp could be removed so yes I agree one single strand if running to the battery.





Triple tree grounding point. Existing were the radio ground and jumper to the area behind where the bars are mounted The items I installed were the amp ground and 14 gauge jumper to frame,





Pre-existing hole I taped for a 5/16x18 screw.





Ground secured.

I had to edit my post because I didn't realize Harley batteries are grounded to frame. A quick Google search told me different.
