The Datsun Truck 320 generator is mounted on the front left side of the engine and is driven by a fan belt at 1.34 times the speed of crankshaft. As shown in below diagram of the generating system. The generator (-) terminal is grounded to the car body and the (+) circuit lines goes through the voltage regulator and ammeter to charge the battery. The generator is a constant – voltage type equipped with a carbon pile type.

The constant-voltage type generator, when charging, maintains a fixed voltage at the generator terminals regardless of the vehicle speed, that is, over a wide range of engine speeds and also produces an output conforming to the load. In other words, conforming to the state of battery charge, the charging current is automatically regulated, preventing excessive charging or discharging. When the load is increased suddenly, the output will increase correspondingly so that the life of the battery will be prolonged.
