You probably noticed that the Trace Legend Series II inverter/chargers have a third battery terminal
labeled Vehicle Chassis Ground (the green terminal on the left side of the unit). The purpose of this
third terminal is be sure that all DC load current into or out of the battery bank will flow through the
internal shunt of the inverter. The internal shunt is connected between the black battery negative
terminal and the green chassis ground terminal of the inverter (See Figure 3, DC Wiring Diagram on
Page 30.)
Because all DC loads in a vehicle are generally connected to a common chassis ground and not
directly to the battery negative (in a negative ground system), all DC current in the system will at
some point pass through the chassis and then into the battery bank. If the inverter is in this loop the
net current flow is easily monitored. Thus, the RC7 remote controls battery fuel gauge feature is
