ELECTRICAL SYSTEMS - CHASSIS — 9
Inspect the alternator for damage.
Check belt pulley for wear. Replace as
needed.
DO NOT disconnect the battery or
battery wire from the alternator with the
engine running. This can damage the
alternator or regulator.
The pulley for the alternator should be
torqued to 80 ft. lbs.
Chassis battery voltage with the engine
OFF should range from 12.2 to 12.7
Volt DC.
Chassis battery voltage with the engine at
idle should range 13.5 to 14.2 Volts DC.
The output of the alternator range is 13.6
to 15.4 Volts DC. Connect a volt meter
to the (B+) terminal of the alternator and
chassis ground. Idle the engine up to
1200 RPM.
Connect a clamp-on amp-meter, if
available, to the positive battery cable to
verify the battery state/rate of charge.
CAUTION:
The alternator is not a battery charger.
The alternator is designed to maintain
proper electrical system voltage. A
House battery with a low state of
charge, or a dead battery, will overheat
and damage the alternator.

STEERING COLUMN & SMART WHEEL
The steering wheel system consists of
electronic modules enclosed in the steering
wheel and the Master Controller typically
located in the front run box. Four wires utilizing
a "clock-spring" connector in the steering
column accomplish communication between
the steering wheel and the Master Controller.
The Master Controller decodes the signal for the
closed switch and operates the corresponding
outputs for that function. Two additional wires
provide power and ground for the steering wheel
backlighting.
The 3 Amp fuse on the Master Controller is
for backlighting the switch panel. LED draw is
approximately 20 mA.
Another function of the smart wheel is the
"High Idle" feature.

Smart Wheel Operation

HORN:
The horn bar on the steering wheel sends the
appropriate signal to the Master Controller
causing the HORN output to activate while the
switch is pressed.
HEADLAMP FLASH:
The headlights must be on low
beam for this switch to operate.
Press and hold the headlamp
fl ash switch to dim headlights
from low beam to daytime running
light brightness (approximately 80%
of low beam). Daytime running lights are
activated with the ignition and cannot be
turned off. The daytime running light module
is located in the front electrical bay.
Cruise Function:
ON/OFF - Cycles cruise system ON and
OFF.
CANCEL - Signals cruise system to
disengage without losing the current
speed memory setting.
RES (RESUME) - Actuates cruise
resume function of engine controller.
SET - Sets cruise speed.
WARNING:
DO NOT use cruise control in heavy
traffic or on roads that are winding,
slippery or unpaved. DO NOT shift the
transmission into "N" (Neutral) with the
cruise control on. High engine RPM run
up will occur until the cruise control is
080508a
turned off.
