1.2.1.9 ELEC panel
The real electrical system of the F-16 is quite complicated with a main AC power
system distributing current to the non-essential, essential and emergency buses, a
standby AC power system distributing power to the essential and emergency buses,
an emergency AC power supply distributing power to the emergency buses and a DC
power and FLCS power supply.
The main power switch is a three-position switch.
In OFF no electrical system receives power from the main generator, standby generator or battery. All
systems are cold.
In BATT the aircraft battery is connected and the battery bus is powered.
In MAIN the MAIN generator and standby generator provide power to the aircraft systems.
The CAUTION RESET push button is the only way to reset an ELEC fault, displayed as the amber
ELEC SYS caution light. It also resets the main and standby generators.
FLCS PMG indicator light: when it lights up it means that none of the FLCS branches are receiving
power from the FLCS PMG (Permanent Magnet Generator). Basically that means the primary power
source for the FLCS has failed.
When the MAIN GEN indicator comes on it means that the main generator is not connected to the
non-essential AC buses. In all likelihood the main generator has failed.
Likewise, when the STBY GEN indicator light up it means that standby generator power is not
available.
When the EPU GEN indicator light comes on it means the EPU has been commanded ON but the
EPU generator is not providing power to the emergency buses. Be aware that the light does not
function with the EPU in OFF (WOW) and the engine running.
When the EPU PMG indicator light comes on it means that the EPU has been commanded ON but
the EPU is unable to provide power to the FLCS branches (normally through the EPU PMG).
The two lower indicators refer to the aircraft battery.
When the TO FLCS indicator lights up it means that the battery power is going to one or more FLCS
branches. Basically the battery is powering the FLCS and will deplete fast.
When the FLCS RLY indicator light comes on it means that one or more FLCS branches
aren’t
getting adequate voltage from the battery.
When the FAIL indicator light comes up it means that the aircraft battery has failed or is failing to
charge (on the ground).
