Thanks for the add. Trying to add a USB charging accessory to our 2008 Electric Yamaha cart. Thought I would splice headlights line and prevent trying to add a reducer. After splicing and reconnecting, headlights nor USB worked. Thought maybe there wasn't enough power, so took off the usb device and was left back with just the headlights (but now spliced). Headlights still don't work. I had checked USB device worked before splicing by taking headlight wires into USB, so know that isn't the issue. Could I have cut power by attempting the slice, so now not enough juice to run headlights? Do I just need to rewire and start over or am I missing something? Thanks for help!!
