[QUOTE="Ruggie74, post: 8704746, member: 679656"] So after some more research today, I was able to find this guy who upgraded some of the wiring in a 2012 Sonata: [MEDIA=youtube]XbFBV9OfdPQ[/MEDIA] Watching part 5 and 6 of that video, and also asking him in the comments for clarification (since I admittedly don't have a CLUE what I am doing), [U][B]as far as I can tell[/B][/U], he ended up [B]replacing[/B] only the alternator negative wire to chassis ground. It looks like he grounded the wire to the same place as the battery negative wire is grounded to (and cleaned both mounting points up a bit with sanding/paint covering). He [U]did not[/U] do an alternator positive wire to battery positive terminal and he did not do a battery negative wire to chassis ground. He mentioned the battery negative wire's ECM in the comments for his reasoning to not touch anything there -- so thank you for that information Diego. Now I'm wondering if this would be enough to solve the dimming problem in this vehicle (and Diego's KIA). I guess there is only one way to find out; so, I'm going to do a bit more research and probably end up trying to tackle this sometime soon and will report back. Any input or suggestions would be unbelievably appreciated, since I am, after all, a complete noob! [/QUOTE]
