Where do the 2 wires on alternator go?

Wiring Connections Exciter wire is connected to the L terminal of an alternator and is used to turn on the voltage regulator. Excitor wire is needed to generate the voltage required for the alternator to start running. The positive and negative cables are small and connected to the respective terminals of the battery.


How does a Denso alternator work?

Driven by the engine, the alternator (along with the belt and the regulator) converts mechanical power into electrical energy that supplies various loads in the vehicle system. During normal driving conditions, this electrical energy will be used to recharge the car battery.


How do you fix a Denso alternator?


What controls an alternator?

The current flowing through the rotating solenoid (rotor) is the decisive factor for regulating the output generated by the alternator. This current is used to alter the magnetic field. It is controlled by the alternator regulator based on the battery voltage, which has been measured in advance.


What is W terminal on alternator?

The W terminal generally outputs an unrectified AC voltage, the frequency of which is proportional to the engine speed.


How do you connect an alternator directly to a battery?

Make sure that it is bolted securely to the alternator mount. Attach a cable directly from the alternator output post to the positive side of the battery. This allows for full output from the alternator to the battery when heavy electrical demands are placed on the alternator. Wire the alternator controls.
