Removal and installation of the generator

The car has the generator of three-phase alternating current. Depending on model and the equipment generators of various power can be installed.

If subsequently on the car electric devices with high electricity consumption are installed, it is necessary to check whether the power of the available generator is sufficient. If necessary it is necessary to install the new generator of higher power.


The alternating voltage created by the generator will be transformed by rectifier diodes to the constant tension which makes a charge of the rechargeable battery. The regulator changes charge current so that working tension irrespective of speed remained to constants.

The generator can be replaced. The damaged generator upon purchase of the repaired or new generator is set off. Therefore take away the failed generator with yourself.
