E5. Battery Charging System
Failure
The red battery charging system
light indicates a problem has
been detected in the charging
system, and system voltage is at
or below 24.0 volts. If this light
illuminates, the operator should safely stop the truck,
move the directional control lever to PARK, shut the
engine off, and notify maintenance personnel imme-
diately. If truck operation continues, and the battery
voltage drops below 20.0 volts, the propulsion sys-
tem will not operate, but retarding will still be avail-
able.
A6. No Propel
The red "no propel" light indi-
cates a fault has occurred which
has eliminated the propulsion
capability. If this condition
occurs, the operator
safely stop the truck, move the
directional control lever to PARK, shut down the
engine, and notify maintenance personnel, immedi-
ately.
B6. Propel System @ Rest
The amber "propel system @
rest" light is used to indicate that
the AC drive system is de-ener-
gized and propulsion is not avail-
able. This light is activated when
the instrument panel rest switch
is turned ON and the AC drive system is de-ener-
gized. The three link energized lights (one on rear of
the center console inside the operator cab, and two
on the deck-mounted control cabinets) should NOT
be illuminated at this time.

C6. Propel System Not Ready
The amber indicator light func-
tions during start-up much like
the hour glass icon on a com-
puter screen. This light indicates
the computer is in the process
of performing the self-diagnos-
tics and set-up functions at start-up. Propulsion will
not be available at this time.
D6. Reduced Propulsion
The amber "reduced propulsion"
light is used to indicate that the
full AC drive system performance
in propulsion is not available. At
this time, the only event that
should activate this light is the
use of "limp home mode". This mode of operation
requires a technician to enable.
E6. Retard At Continuous
Level
The amber retard at continuous
level light indicates that the
retarding effort is at the continu-
ous level. The operator should
control the speed of the truck in
accordance to the "continuous" speeds on the
GRADE/SPEED RETARD CHART on page 32-7.
