  • B+ Terminal: This is the main output terminal, directly connected to the battery's positive terminal. It carries the full charging current to the battery.
  • IG (Ignition) Terminal: This terminal receives a signal from the ignition switch. When the ignition is turned on, it powers the alternator's regulator.
  • L (Lamp) Terminal: Also known as the warning light terminal, this connects to the battery warning light on your dashboard. It allows the light to illuminate when the engine is off or if there's a charging issue.
  • S (Sense) Terminal: This terminal is connected directly to the battery or a main power distribution point. It allows the alternator to sense the battery's voltage and adjust its output accordingly.

A typical setup might look like this:

Alternator Terminal Connection To
B+ Battery Positive (+)
IG Ignition Switch/Accessory Power
L Dashboard Warning Lamp
S Battery Positive (+) or Main Power Point
