for data about the engine control system.
2. Description and Operation
Figure 1 shows the simplified schematic diagram of the starter system. The system operates off a 12
VDC supply.
The TAE 125 Diesel engine has a small, high-powered electric starter. The starter motor is located on
the left side of the engine near the front. It has an integral solenoid to connect the starter motor to the
relay junction box bus. Either the airplane battery or the external power system can supply the this bus
for the starter.
The ELECTRIC MASTER key switch (marked OFF ON START) is located on the bottom left of the
instrument panel. Turn the key clockwise against the spring to operate the starter. Release the key
when the engine starts. The spring returns the key to the ON position.
A starter relay located on the instrument panel floor controls the current to the starter solenoid. An
ENGINE MASTER switch located on the bottom left of the instrument panel controls the ground
connection for the starter relay. This switch must be set to ON for the starter system to operate.
A START warning light on the annunciator panel comes ON when there is power to the starter. If this
light stays on after the engine has started, set the ELECTRIC MASTER key switch and the ENGINE
MASTER switch to OFF.
If necessary during starting, the engine control unit operates the glow plugs to heat intake air for the
engine.
