Instrument Panel - Elect. Cont. 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 (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). RG11169 –UN–01NOV00 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.
