My daily’s currently down so I figured I’d fix up my 03 maxima that needed a lower control arm,it’s been sitting for roughly about 6 months and it ran fine prior but now it has no power to anything past the battery,when replacing the lca I had the key turned on acc. And when a sudden blow would hit when replacing the lca I could hear the door dinger go off but it would stop a few seconds later,this happened twice when working on it,I suspected a loose ground somewhere so checked the battery ground on both ends and it seemed fine and tight on both ends but since it’s intermittent my guess is a ground issue and I can’t find any online diagrams for where any other grounds are,I cleaned the battery and terminals up and still no power,I’m currently out of a vehicle and soon to be out of a job so any help is greatly appreciated
