[KO 23] SILAKAN SUBSCRIBE: Charging System: Rangkaian Sistem Pengisian Konvensional

Summary

The video explains the wiring relationships in a conventional automotive charging system. Building on earlier lessons about alternators and charging-system components, the instructor focuses on which terminals connect to one another. Although the complete circuit may look complicated, tracing it component by component makes it easier to understand.

Main Components and Terminals

• Battery: Positive and negative terminals.
• Ignition switch: Terminals B (battery), IG (ignition), ST (starter), and ACC (accessories).
• Regulator: Terminals IG, N, F, E, B, and L.
• Alternator: Socket terminals F, E, and N, plus output terminal B.
• Charging indicator lamp: Connected between the ignition-switch side of the circuit and the regulator’s L terminal.

Terminal Connections

• Battery positive connects to B on the ignition switch.
• Ignition-switch IG connects to regulator IG.
• Regulator and alternator terminals connect one-to-one:
  • F to F
  • E to E — the ground connection
  • N to N
  • B to B
• Alternator B connects to battery positive, providing the route for charging the battery.
• The charging indicator lamp connects to ignition-switch IG and regulator L.

Basic Operating Conditions

Ignition on, engine not running: Current from the battery passes through the ignition switch. The indicator lamp lights, and current also reaches the regulator and alternator field circuit. Field current flows through the rotor and returns to ground, creating a magnetic field.

Engine running: The alternator generates electrical current. Its B terminal supplies charging current to the battery, while the N connection links the alternator and regulator. The video describes the alternator as supplying the system while the battery is being charged.

The instructor also briefly identifies internal parts shown in the circuit diagram: the alternator’s rotor, slip rings, star-connected stator, and diodes; and the regulator’s voltage-regulator and voltage-relay coils with contact points. A fuller explanation of circuit operation and charging voltage is deferred to later lessons.
