WebJun 2, 2014 · Go to your service information and find out how much current draw the vehicle manufacturer allows. For most vehicles with a single battery, this current draw will be somewhere between 20 mA (0.02 amps) to 40 mA (0.04 amps). Once you know how much current is allowed, you will have a target for which to shoot. WebA normal parasitic draw is about 50mA or 0.05 amps, but the range can be anywhere from about 0.03 to 0.085 amps (30-85mA). If your car gets above 50mA, then it might be completely normal for your vehicle — especially if it’s new — but you might want to look into it further by running a parasitic draw test or having a mechanic do it for ...
