Unleashing Energy Efficiency Harnessing Can Meter Shunts to Identify Parasitic Draw

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 ... If I want to use a shunt resistor in series with battery cable on negative side can I simply use one channel and measure vdrop across the resistor and set ... Meter connection to observe parasitic current drain is correct. You can leave the bulb in place. If the meter displays more than ~160 Ma (milli- ... The primary tool used is a voltmeter. However, they do start by measuring the "sleep mode" current draw at the battery. This can often be done using the ammeter ... 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 ... I've installed a current meter and shunt in my golf cart. And I've ... When the cart is stopped and key in off position, there is a current draw ... Lisle sells an inexpensive parasitic draw adapter, with fuses, to use with a meter; it's not a rocket science design, but for the $, it's ...
