Connecting Amp Meters to Shunt Bars
Basic Analog Meter Wiring Diagram
Simply hook up the two terminals from the meter to each side of the shunt (one wire per side). Then place your shunt in series with the load or energy source you wish to monitor.
For instance, if you will be measuring the current from a solar panel, then terminate the positive wire from the solar panel to one side of the shunt. From the other side of the shunt, simply continue on to your charge controller (or disconnect, etc.).
If your meter reads backwards, then simply switch the wires on the shunt going to the meter.
