- Battery Positive (B+): This is the main power output from the alternator, directly connecting to the battery's positive terminal.
- Ignition/Sense (L or I): This wire typically receives power from the ignition switch and signals the alternator to begin charging. It also monitors the battery voltage.
- Field (F): This wire controls the alternator's output voltage by regulating the magnetic field strength.
- Ground (G or sometimes integrated into the housing): A proper ground connection is essential for the alternator to function correctly.
To get a better understanding, let's consider a simplified representation of the connections you might see on a typical 2004 Chevy Silverado alternator wiring diagram:
| Alternator Terminal | Function | Typical Wire Color |
|---|---|---|
| B+ | Battery Output | Red |
| L/I | Ignition Sense | Yellow/Black |
