Can someone help? my understanding so far: Buy a battery to USB transformer (12v to 5v). Wire it up directly to the battery. Will be live all the time. Potential to fry the battery if the device connected tries to draw too much power I stumbled on this site for my bike: http://faq.ninja250.org/wiki/What_are_these_wires_that_aren't_attached_to_anything? it seems a connection to the battery already exists, so all i have to do is wire up the 12v tro 5v transformer to the leads? is this right? i also read about wiring up my own fuse so the device cant fry the battery. is this hard to do?
