this is actually done wrong as far as i know, depending on how you ran the rest of your wires atleast. that little plate you soldered the new wire to is the ground strap, youre supposed to remove the original wire from that plate and solder your new wire only to the original wire. but i believe this works as long as you dont ground your dc system to the frame? but hey, if it works run with it! have you had any problems? ive tried 4 different voltage regulators and still get 20+ volts when i rev. any advice?
