from 11,8 to 15 V (TOYOTA)
(Communication) General term for physical interface,
Serial Device), BSS (Bit Synchronized Signal) or LIN (Local
Interconnect Network)
Direct indication on control interface and alternator
diagnostics, conducted under LIN protocol (Local

Output of voltage regulator
Output of one of alternator stator windings. Used for
measuring alternator driving voltage
(Wave) Output of one of alternator stator windings for
connection of tachometers in diesel engine cars
(Null) Output of average stator winding point. Usually used
to regulate alternator operability with mechanically
regulated voltage
by an indicator lamp
(Dummy) Blank, no connection, mostly in Japanese cars
