Attention! When installing additional equipment, check whether the previous generator has sufficient power, and install a more powerful generator and battery if necessary. The generator is driven by the crankshaft via a V-belt. The diesel engine has an additional brake booster vacuum pump installed on the generator shaft. The generator rotor with the excitation winding rotates inside the stationary stator winding at a speed twice that of the crankshaft. The excitation current flows through the excitation winding via the carbon brushes and slip rings. This creates a magnetic field.
The position of the magnetic field relative to the stator winding constantly changes in accordance with the rotation of the rotor. Due to this, alternating current is generated in the stator winding.
Since the battery can only be charged with direct current, the alternating current is converted to direct current in the rectifier on the diode board. The voltage regulator changes the charging current by turning the excitation current on and off, according to the state of charge of the battery. At the same time, the regulator maintains the battery voltage at a constant 14 V, regardless of the number of revolutions.
Please note: Depending on the type, the generator may be a returnable item, which means that the cost of the old generator may be offset against the purchase, and the old generator is returned to the manufacturer.
