help! chargeing problem since mad bypass!!

I always run a custom ground wire from the VR mount to a more solid ground than the sheet metal screw the factory relied on. Note that newer cars have special grounding studs scattered around the vehicle. Relying on tentative body connections caused many issues in 60-70's cars. Even 70's Darts changed to a dedicated ground return wire for the headlamps. My 65 Dart relied on a sheet-metal screw right behind the headlamp connector (I improved that).
