The shunt circuit is a different thing from the "power on" light circuit. It is used to measure the + or - amps in or out of the battery on the older Airstreams. It is an ammeter circuit, using a shunt built into the old Univolts so only a small amount of current needs to be run to the actual meter in the control center.
So, actually there are two small wire circuits that feed information to the display/control center. One is the power on light, the other is the one for the ammeter fed from the shunt.
