My batter y keeps draining overnight and once jumped it starts right up. I just replaced the negative cable, the positives cables are fine. I gave it jump and drove it for about a half hour, parked came back and it won't start. At autozone they made me by a digital multimeter and told me to check the fuses to see which one is causing the drain. I've searched the forum and read alot up on this but still kinda confused on how to do this or where to start. Like what should this thing read normally for each fuse or how to set it? If anyone can help thanks in advance.
