I keep seeing 2 different ways people ground their high output alternator. Some ground to frame, some ground to negative battery terminal. Nissan says not to ground to battery but I'm assuming most vehicles say that. I have the big 3 done all 0 gauge. I'm going to run dual 0 gauge grounds and positive post wires. Not sure if Im gonna ground to frame or body. Nissan is gonna install the alternator for me. Any input is appreciated. What's up User1 , if u see this. Lol
