NOTES

(for Blackout Lighting Control Switch)

Carrier warning/indicator lights are all blackout-safe,

and are therefore not controlled by the Blackout

Lighting Control Switch (16, Figure 5-1). The circuits

identified above are the only other circuits that are

enabled in the specified conditions: All other circuits

are disabled.

With Blackout Lighting Control Switch (16) in the OFF

position (i.e., all carrier lighting circuits disabled), the

backup alarm and the carrier backup/ superstructure

driving light circuits are enabled from the

superstructure cab only.

The carrier backup/

superstructure driving lights can be turned on by

placing the DRIVE/PANEL Light Switch (52, Figure 5-

2) in the on position. The backup alarm will sound

only when the superstructure Transmission Shift

Lever (48) is placed in one of the R (reverse)

positions.

With the blackout lighting control switch in either

Normal mode position, the carrier backup/

superstructure driving lights will be controlled by the

position of the carrier Transmission Shift Lever (6,

Figure 5-1) regardless of what position (on or off) the

superstructure cab DRIVE/PANEL Light Switch (52,

Figure 5-2) is in. For example, these lights will turn

on if the carrier transmission lever is placed in one of

the R (reverse) positions and off when in N (neutral)

or in one of the F (forward) positions.

When the blackout lighting control switch is in either

blackout mode position, all power to the

superstructure functions is disabled including the

control panel illumination and warning/indicator lights.

WATER TEMPerature Gauge (17). The gauge is located on the middle left side of the

front console panel. The gauge receives a signal from a sending unit in the engine coolant

system and indicates the engine temperature on a dual scale calibrated from 100 to 280 F

and 38 to 138 C.

Left Turn Signal Indicator (18). The indicator is located on the upper left of the front

console panel. The indicator lights when the Turn Signal Lever (15, Figure 5-1) is

positioned for a left turn.

Transmission OIL TEMPerature Gauge (19). The gauge is located on the upper left side

of the front console panel. The gauge indicates transmission oil temperature as sensed by

a transducer in the transmission oil lines. Indication is on a dual scale which is graduated

from 160 to 320 F and 60 to 160 C.
