you won't lose any power. they add a totally different circuit in. there will be 2 new wires coming out of your ignition cover. wire in a voltage regulator in parallel to keep voltage at 12V. my Electrosport stator came with a very simple schematic. I assume the Moose one will also. It is VERY BASIC wiring setup - very easy, like grade school level. Whatever setup you get I can email you the picture/schematic are you also gonna add battery to it?
