CHAPTER 80
STARTING

% Section 80-00 % Starting - Lycoming Engine
1. General
% This Section tells you about the system that cranks the Lycoming engine for starting.
Note:  Equipment which is certified for installation in the DA 40 is listed in Section 6.5 of the Airplane Flight Manual. Such equipment may be installed in accordance with the Airplane Maintenance Manual.
Any equipment which is not listed in Section 6.5 of the Airplane Flight Manual is called "Additional Equipment". The installation of Additional Equipment is a modification which must be handled in accordance with national regulations or a Service Bulletin.
2. Description
Figure 1 shows a schematic diagram for the engine starter system. The system has these components:
A. Ignition Switch
The DA 40 has the usual ignition switch. The ignition switch is in the lower instrument panel, on the left. You operate the ignition switch with a key. You can set the ignition switch to any one of five positions. To set the START position you must hold the ignition key against a spring. If you release the key in the START position, the spring will turn the key counter-clockwise to the BOTH position. The switch has these positions:
) OFF: Both the magnetos are grounded. The starter is off.
) R: The right magneto is live, the left magneto is grounded. The starter is off.
) L: The left magneto is live, the right magneto is grounded. The starter is off.
) BOTH: Both the magnetos are live. The starter is off.
) START: Both magnetos are live. The starter is on.
You cannot repair the ignition switch. Refer to Section 74-00 for the procedure to replace the ignition switch.

B. Starter Relay
The DA 40 has a heavy-duty starter relay. The starter relay attaches to a mounting on the engine firewall in the relay mounting box. The relay has two small connectors for the control cables and two large connectors for the power cables. A cable for the starter-power-on-light also attaches to the starter relay. It connects to the same terminal as the power lead to the starter.
C. Starter Motor
The DA 40 has a lightweight starter motor. The motor attaches to the bottom of the engine crankcase at the front.
The starter has a pre-engage solenoid. The pre-engage solenoid moves the starter-pinion to engage with the engine-starter-gear. It also makes the electrical contacts for the starter motor. When the starter pinion is fully engaged with the engine-starter-gear, the electrical circuit for the starter motor is made and the starter turns.
