Instrument Panel For Earlier Engines
Engine Preheater Indicator (Optional)
The engine preheater indicator (K) lights up while the
engine is being preheated for cold weather starting. When
the engine is warmed up, the light goes off, indicating the
engine can now be started.
Key Start Switch
The three-position key start switch (L) controls the engine
electrical system. When the key switch is turned clockwise
to “START”, the engine will crank. When the engine starts,
the key is released and returns to the “ON” (RUN)
position.
Override Shutdown Rocker Switch
Switch will be present, but may not be active, depending
on engine controller (ECU) options originally selected. If
switch is active, pressing the upper half of the override
shutdown switch (M) will override an engine shutdown
signal. The switch must be pressed within 30 seconds to
prevent undesired shutdown of engine. Pressing this
switch will override the engine shutdown for 30 seconds at
a time to move vehicle to a safe location.
High-Low Speed Select Rocker Switch
This instrument panel has two versions, one with a two
position switch as shown, and one with a three position
switch. The two position switch has high/low and is used
to set the engine operating speeds at slow (turtle) or fast
(rabbit). Factory preset idle speeds can also be adjusted
using bump speed enable switch (O) with speed select
switch (P).
The three position switch has Slow (turtle), Middle (Adj)
and Fast (rabbit) settings. Slow (turtle) position is factory
preset at low engine idle, while middle (ADJ) position is
factory set at high engine idle. To adjust engine speeds,
See Changing Engine Speeds in Section 18.
