I have replaced the stock battery terminals and run some additional ground cables to the engine and body. I've noticed that a ground wire (maybe 8 - 10 gauge) is connected directly to the battery, which I think comes from the fuse/relay block ground terminal. This wire gets hot when the ac fan is on speed 3 or 4. Why would vw run a separate ground connection instead of grounding to the chassis or ground point next to the fuse block? I am suprised the insulation on this wire is still there - maybe it is because more current is flowing through the system with my upgraded connections at the battery?
