Car has been sitting under a cover. Started right up but the next day the battery was dead. Charged it up but it did it again. I bought a new battery and after sitting a few days dead again. Charged it up. I know very little about cars but looked on Youtube (Thanks EricTheCarGuy) and set up my multimeter to the neg cable and neg battery terminal. It showed 3.5 amps. I only found the one fuse box to the left of the drivers seat and pulled out each of the fuses one by one but nothing changed. No visor, dome or hood light was on. If I let the dome light on it would go to around 4. So compared to that somethings really putting a load on. Is that all the fuses I can check? Any suggestion for what someone with my basic level can try further are appreciated. Thanks
