A small parasitic draw under 1 Amp will take a few days to drain a battery; over 1 Amp could drain a battery overnight. Armed with this information, we can test for a voltage drop across fuses to identify those circuits that are live and causing your vehicle’s battery to drain. Before you start testing, there are a few things you need to know. Just: - Remove the ground terminal from one battery. Connect the ammeter between the battery terminal and the cable clamp. - Remove the ground terminal from the other battery. When battery drain drops below 50 mA, it has passed the test.
