Here's a simplified look at the sequence of events shown in a typical 99 Dodge Ram Ignition Wiring Diagram:
- When the key is turned to the "ON" position, power flows from the battery through fuses to the ignition system.
- This powers the ignition coil, preparing it to generate a spark.
- When the key is turned to the "START" position, power is routed to the starter solenoid, engaging the starter motor.
- Once the engine starts, the key is released back to the "ON" position, and the ignition system continues to provide spark to the spark plugs.
