INSUFFICIENT RATE OF CHARGE
When the overvoltage circuit, or other fault, opens the alternator
(START/ALT) circuit breaker and de-energizes the alternator, a
discharge (-) current will be shown on the main battery ammeter
(AMPS) and the red LOW VOLTS annunciator will be displayed on the
PFD. The Alternator Internal Control Unit (AICU) can de-energize the
alternator due to minor disturbances in the electrical system, resulting
in a nuisance opening of the START/ALT circuit breaker. If this
happens, an attempt should be made to energize the alternator system.
To energize the alternator system
1.
MASTER Switch (ALT Only) - OFF
2.
START/ALT Circuit Breaker - CHECK IN
3.
MASTER Switch (ALT Only) - ON
If the problem was a minor AICU disturbance in the electrical system,
normal main battery charging will start. A charge (+) current will be
shown on the main battery ammeter (AMPS) and the LOW VOLTS
annunciator will go off.
If the red LOW VOLTS annunciator is displayed and a discharge (-)
current is still shown on the AMPS Indicator, there is an alternator
system problem. Do not repeat steps to energize the alternator system.
Decrease the electrical load on the battery by de-energizing
nonessential electrical equipment and avionics (consider exterior lights
and radio equipment) because the battery can supply the electrical
system for only a short time. Reduce electrical load as soon as possible
to extend the life of the battery for landing. Land as soon as practical.
