simultaneously. However, if a situation so demands, it is possible to
switchtoeitherbatteryONoralternator OFF only.
The AVIONIC 1 and AVIONIC 2 (IFR) switches are located on the
left part of the instrument panel, right to the ALT / BAT switch.
They control the flow of to the avionic bus 1 and the
avionic bus 2 (IFR).
For IFR equipped aircraft the bus 1 and bus 2 switches provide the
option to remove power supply from the avionic buses separately.
This provides the capability to disconnect nonessential electrical
accessories in the event of an alternator failure.
To avoid damage to the avionics equipment the AVIONIC power
switches should be placed in the OFF position prior to turning the
ALT / BAT switch ON or OFF, starting the engine, or applying an
external power source.

Ammeter
The ammeter is integrated in the VM 1000 Engine Management
System. The amperage is displayed on the VM 1000 indicator in the
lowerrightareabothgraphicallyanddigitally(SeeFig. 7-6).
The ammeter system functions as an “alternator load meter”
displaying current flow from the alternator to aircraft electrical
system.
Additionally the system has a built-in warning that is coupled with
the EC 100. When the alternator does not produce enough power for
the electrical system, the EC 100 will automatically begin to flash the
warning “AMPS TO LOW” and a pulsing audio tone will be present.
