Message: <blockquote data-quote="keep_hope_alive" data-source="post: 8494360" data-attributes="member: 576029">a typical shunt is 200A 75mV.  meaning at 200A of current there is a 0.075V drop across the shunt.  the ammeter measures the voltage drop and calculates the current.  the shunt is matched to the meter.typical to place the shunt in series with the battery ground wire.  if you place the shunt on the amp ground wire, you have an opportunity for noise, but try it first.</blockquote>
