Alternator Terminals

Toyota's high-speed alternator has the following terminals: "B", "IG", "S", "U', and "17".

When the ignition switch is "on," battery current is supplied to the regulator through a wire connected between the switch and terminal "IG". When the alternator is charging, the charging current flows through a large wire connected between terminal "B" and the battery. At the same time, battery voltage is monitored for the MIC regulator through terminal "S". The regulator will increase or decrease rotor field strength as needed. The indicator lamp circuit is connected through terminal "U'. If there is no output, the lamp will be lit. The rotor field coil is connected to terminal "P, which is accessible for testing purposes through a hole in the alternator end frame.
