CONTROLS/INSTRUMENTS
2 - 6
L.H. Lower Control Panel
18175
1. Ignition
This switch has three positions:
OFF
: Ignition is off and key can be removed.
ON
: Ignition is on and key cannot be removed.
START
: Starting position; spring-loaded ignition
switch returns to
ON
position after starting. Igni-
tion key must be returned to
OFF
position before
trying to restart.
Caution:
Do not engage starter for more than
15 seconds. Allow starter time to cool before en-
gaging again. This will prevent starter from over-
heating and will allow the time relay delay to
cool.
2. Battery Master Switch
Both the 12-volt and 24-volt systems are acti-
vated by the master switch located on the L.H.
lower control panel. An indicator light on the L.H.
dashboard will illuminate when the ignition key is
in the
OFF
position and the 12-volts and 24-volts
systems are activated.
Caution:
When parking the coach for an ex-
tended period of time, place the battery master
switch to the
OFF
position.
Note:
When the battery master switch is set to
the
OFF
position, all electrical supply from the
batteries is cut off, with the exception of battery
equalizer check module, ECM ignition and power
supply, ECU power (World transmission), pre-
heater electronic timer, preheater and water re-
circulating pump, prodriver and powerverter.
3. Fast Idle
Push down rocker switch to engage fast idle,
thus increasing engine speed to approximately
1100 rpm. Use this switch for extended stops.
Note:
If parking brake is released and/or trans-
mission is shifted with engine running at fast idle,
engine will reduce its speed to idle and maintain
this rpm as long as parking brake is not applied
and/or transmission is in the neutral position. If
engine is stopped with the fast idle switch in the
ON
position, this control will automatically be
canceled when restarting the engine; the driver
must then shut off, and reset rocker switch to re-
actuate fast idle. Generally, fast idle should be
reduced to low idle before shutting off engine.
4. Cold Starting Aid

Activates the cold starting device in engine com-
partment (see page 4-7).
5. Transmission Retarder

half engine brake and press to the second posi-
tion for a full application of engine brake (see
page 4-3).
6. Stop Engine Override
Push down rocker switch to reset the 30 second
delay period and the shutdown procedure. This
switch can be repeatedly depressed,
i.e. one
pulse is sufficient for each 30 second period
,
for engine power in an emergency situation.
Note:
The
Stop Engine Override
switch will be
operative only if it has been depressed before
the end of the 30 second delay period.
Caution:
The
Stop Engine Override
must be
used only in emergency situations to bring vehi-
cle to a safe stop. Excessive use of this switch
could cause serious damage to the engine.
