Hello. I'm having an issue. I started my car the other day and was 100% normal. I backed up to turn around and everything died as if no battery. The next day, I jumped it and it ran. The next day zero power in every way again and jumping didn't change a thing. Different battery, same thing. Acts like there's no battery installed. Grounds look good, wires to starter and the little red junction box look good. The fuses looked good. Does anyone have any suggestions on where to continue looking?
