I'm going out on a limb here and hoping some Legacy owners read this...
I need to know where is the most ideal place to ground on a 98 Subaru Legacy.
I currently have the grounds bolted to the only real solid bolt in the area, the bolts holding the seats in place (rear support). I took a drill and threw on a wire brush bit, and got rid of most of the paint/primer down to bare metal, and rebolted. I am still running into alternator whine issues coming through, and very loudly might I add. I am going to upgrade the Ground wires from 8 AWG to 4 AWG, clean up the spots more, and hope this works.
Anyone else have any ideas?
