Connections, Connections, Connections, Connections,
After that solder the crimp (see "crimp fix") run a new ground wire from the r/r mounting bolt straight to the battery, and another new one straight from the battery to the engine, also can cut out the connectors between the stator and r/r, and between the r/r and the battery, and butt splice then solder them........anywhere you land new ground wires make sure the metal is clean and paint free and then use some of that nasty white "heat sink compound paste" it will help stop corrosion, use it on the back side of the r/r when you mount it too....essentially you are improving the existing connections and with the ground wires you are parrallelling the existing grounds with better and more directly routed ones, and eliminating the use of the frame for grounding.....
My bike charges at 13.4 at idle with two 100 watt head lamps (cybermax headlight) turned on, and over 14 with the headlights off...and that is with a stock stator and stock r/r.....it's a '99
Installing a headlight kill switch is good too, no point in loading the system with the heaviest load it has when there's no need for it; like when your just warming it up or working on it.......
