Short and simple. I have 1 batt. If I add another batt. JUST for electronics, how do I run #2 battery to my fuse panel? Remember, batt, 1 is already hooked up to fuse panel now. I have a hot lead and the ground going to the fuse panel. Should I get another fuse panel and run the #2 battey to it and disconnect the electronics from the original and put them on the new panel? Simple answers please.
