Harbor Freights. I hid a wire under the tank and ran it directly to the positive Bat. terminal. The Negative wire on VM was connected to a bolt at the front of the bike. It only is on if you push the button. Not a problem for me, just every 30-45 min. I can check that charging system working ok. If voltage drops, hightail it home! 2nd pic not very clear, and you'd think I would have cleaned up the bike a little.
