There are three option for placing the AMPS shunt with the VP-X installed shown on page 7-52 of the latest Skyview Install guide.
Position A only shows flows from and to the battery (Cessna style)
Position B shows the output from the alternator to both battery and the aircraft
Position C show only aircraft load
If you have all your aircraft loads through VP-X then position B or C will display what is going through VP-X. In position C it's shown directly while position B is shown with the VP-X display. I have my shunt in position B. The VP-X display shows 0.8 AMPS going to the battery and 16.5 AMPS going through VP-X for a total of 17.3 which is shown on my AMPS gauge on the engine page.
