[QUOTE="wew lad, post: 8646593, member: 665412"] You are running 1/0 power to the alt right? It may be rated 320a but you'll mostly get ~200a and 280a in short bursts when it's stone cold. 1/0 ground to the alternator, and 1/0 ground to the battery is what you need. An extra 1/0 from the battery to the frame isn't a bad idea. I just used 2-4 awg from the batt ground block to the engine block, and one to the front frame ground. power/ground battery block terminals are necessary You have a GM. Should be easy, it's easier for me because the second alt has a bare bolt i just add a ground lug to. You can either a) get a longer oem stud or b) drill out the back threaded portion of the alt mount and use an aftermarket bolt and then bolt the ground onto the back of the alt case. Your 320 doesn't have a ground stud on the case? [/QUOTE]
