Unleashing the Power of Can Meter Shunts for Advanced Parasitic Draw Detection

I'm trying to measure the load on a car battery when shut off. I'm calling this load “parasitic” because it stay on when the key is removed. In response to Donalex's questions: 1. The power to the float switch and pump remains on with the LED on and off. 2. the negative shunt is on ... Shunts are fine and yes they make up to 500 amp shunts and meters, but this seems overly complicated and unneccesary just to check for parasitic ... A voltage drop is measured across the shunt terminals, which is essentially the same as measuring the drop across the fuse. Never thought of using the voltage ... Remove the negative battery cable and connect the meter between the battery and the cable. Read the power consumption. Typically in a car ... This parasitic draw, when it occurs, is so strong, it'll zap the battery overnight and have even seen it suck down to 5-6 volts left on the battery the next ... Either cable. We actually use a shunt at work. A shunt place in series between the battery and cable can show amp draw on a digital volt meter. You have to put a disconnect on the battery itself to completely stop all parasitic draw. Here aer a couple pictures of the AiLi meter I ... ... meters can't reliably read that low (microvolt signal). There are ... The shunt/amp/volt meter is still showing around ~7A so it looks ... ... can experience a parasitic load of 25-35 milliamps.” But does anyone ... What kind of meter did you use to measure the current draw?
