tinue. If you have a problem with any of the following steps, see the Troubleshooting section of this manual.

A. Check the N1 and N2 for a reading of 000.
B. Check Fuel Flow for a reading of 00.0.
C. Check Oil Pressure for a reading of 00.
D. Check Oil Temp to read ambient temperature.
E. Check Volts for proper reading.
F. Check Amps for proper reading (000 when monitoring the Gen. Out).
G. Check OAT to read ambient temperature outside the aircraft.
H. Check all Annunciators for proper operation.
I. Check gear indications on the System screen to operate properly.
J. Check all other functions on the Main and System screen to operate properly.

does not appear proper during any phase of the start, abort the start. Electronics International
produces Field Test Devices that output signals to emulate ITT, N1, N2, Oil Pressure, Fuel Pressure, Oil
Temperature, Fuel Flow, shunts and Resistive and Capacitive Fuel Sensors. These devices can be used to test
the wiring, connections, functionality and accuracy of the MVP system installed in the aircraft. See E.I.'s
pricelist for more information. Consider testing the installation with Field Test Devices before starting the
aircraft.

Start the aircraft engine. Follow all the airframe and engine manufactures procedures. Check that the values
for each function displayed on the MVP are proper for "engine on" operation. Any problem with a specific
function will be associated with a probe, cable or interconnect between the probe and the EDC for that func-
tion. If you have a problem with any function, see the Troubleshooting section of this manual.

Turn the engine off. Inspect the entire system for interference with controls, loose fittings, connections, clamps,
probes, and inspect for leaks, chafing, obstructions, heat damage and any thing that may cause unsafe flight. Check
that all fittings are tight.
