TB 9-2350-368-25 2-41 SECTION VI. INSTRUMENT PANEL 2-6. INSTRUMENT PANEL. The instrument panel contains the following gages, switches, and indicators: water temp, engine low oil pressure, trans clogged filter, trans high temp, trans low pressure, master power, fuel, battery voltage, fuel pump, glow plug, starter, and preheater. STE-ICE is also contained within the instrument panel with external connectors. The tachometer MS35916-2 (6680-00-825-2076) may or may not be in the instrument panel. It was found that the tachometer, when hand-held and attached directly to the engine, works better for moving around the engine and making adjustments. a.
