Keeping this in view, what are the 3 wires on an alternator?
The three wire types in a three-wire alternator include the battery positive wire, the voltage sensing wire, and the ignition input wire. The battery positive wire connects to the starter. The voltage sensing wire connects to the battery, and the ignition wire connects from the alternator to the key switch.
Secondly, what are the terminals on an alternator? Alternator Components
- S terminal - Senses battery voltage.
- IG terminal - Ignition switch that turns the voltage regulator on.
- L terminal - Closes the circuit to the warning lamp.
- B terminal - Main alternator output terminal (connected to the battery)
- F terminal - Full-field bypass for regulator.
Herein, where does the alternator wire connect to?
This wire connects to the battery, either directly, or via some connection in the main battery supply circuit. Typically, it connects to the battery side of the fuse block. Its purpose is to monitor the system voltage, and increases or decreases the charging rate, depending on the system load and/or battery condition.
What does R and F mean on an alternator?
The R and F terminals are the 'Reference' or voltage sense terminal and the 'Field' terminal.
