Figure 42–Recommended Amps Shunt Locations (simplified electrical diagram)
Use two ¼” ring terminals sized appropriately for the high-current wire gauge you will be
routing to and from the ammeter shunt. Cut the wire where you would like to install the
ammeter shunt. Strip the wire and crimp on the ring terminals. Using a Phillips screwdriver,
remove the two large screws (one on either end of the shunt), slip the ring terminals on, and
screw them back into the base.
We highly recommend that you fuse both the connections between the shunt and the SkyView
as shown in Figure 43 below. There are two methods for accomplishing this. You may simply
connect two 1 amp fuses in-line between the shunt and the SkyView. Or, you may use butt
splices to connect 1” to 2” (25mm to 50mm) sections of 26 AWG wire between the shunt and
each of the Amps leads connecting to the SkyView. These fusible links are a simple and cost-
effective way to protect against short-circuits (fusible links in LSA installations may not be
ASTM-compliant).

Next, crimp the two supplied #8 ring terminals onto the wires using the fusing method chosen
above. Connect the other ends of the fuses to the Amps High and Amps Low leads (pins 24 and
25) on the EMS 37-pin Main Sensor Harness. Unscrew the two smaller screws on the ammeter
