Key Components and Ignition Switch Structure
The ignition switch is more than just a simple on/off switch. It is comprised of several terminals, each serving a specific function. Typical terminals include:
- B (Battery): Connects directly to the battery positive terminal.
- S (Starter): Activates the starter solenoid.
- I (Ignition): Powers the ignition system (coil, spark plug).
- G (Ground): Connects to the grounding system.
- L (Lights): Powers the mower’s lights (if equipped).
A Craftsman riding mower ignition switch diagram illustrates how these terminals are connected within the switch and to other components in the mowers electrical system. Consulting the correct diagram for your specific Craftsman model is crucial.
