SV-EMS-220 Installation and ConfigurationAmmeter ShuntThe ammeter shunt should be mounted so that themetal part of the shunt cannot touch any part of theaircraft. The ammeter shunt can be installed in yourelectrical system in one of three locations as shown inFigure 35.If you have a Vertical Power VP-X system in youraircraft, use either position A or position B. Position C is not useful in a VP-X installationbecause the VP-X measures aircraft loads directly. Position A–Ammeter indicates current flow intoor out of your battery. In this position, it willshow both positive and negative currents(i.e., -60 amps to +60 amps). Position B–Ammeter indicates only the positivecurrents flowing from the alternator to boththe battery and aircraft loads.

(0A-60A)Note that the ammeter shunt is not designed for the high current required by thestarter and must not be installed in the electrical path between the battery andstarter.The Ammeter Shunt packaging may be marked 40mV/40A. However, Dynon ratesthe shunt for up to 60A loads.Figure 35–Recommended Amps Shunt Locations (simplified electrical diagram)Use two ¼” ring terminals sized appropriately for the high-current wire gauge you will berouting to and from the ammeter shunt. Cut the wire where you would like to install theSkyView System Installation Guide - Revision J 7-35
