10.7.2 Starter device
The starter arrangement is shown in Figure 10.10.
Figure 10.10 Starter arrangement.
Once you inserted the key into the ignition lock and turned it, the retraction relay starts, the core moves inside the winding and, drags the lever. This moves the starter gear together with the overrunning clutch in order to engage with the flywheel ring gear. When the ignition key is subsequently turned in the lock, the retraction relay core will continue to move until the contacts are connected. As soon as the contacts are connected, an electric current will flow through them from the battery pack to the brushes and the slip ring. The starter armature will start rotating, transmitting its rotation through the gear to the flywheel and crankshaft, respectively. Once the engine is started, you will release the key and it will return from the unfastened start ignition position. At this point, the power supply will be disconnected from the retraction relay winding, and the core will return to its original position under the action of the return spring. The starter gear will also return to its original position.
