The electrical characteristics of the generator should never be tested in a circuit with a voltage greater than 40 V. Diodes should not be tested in circuits with a DC voltage greater than 24 V. It is recommended to clean the generator parts with white spirit or trichloroethylene, and immediately after cleaning, dry with compressed air (especially the windings). When inspecting the parts, check:
- condition of the brushes, degree of their wear, fit to the rings and pressing force;
- appearance of contact rings and inter-contact gaps. Clean only with fine-grained sandpaper;
- condition of the bearings. The grease in them is designed for their entire service life;
- appearance of the rotor and stator. Make sure that their windings have no breaks or signs of burning.
Adjusting the drive belt tension
Loosen the generator mounting bolts to the cylinder block and the tension bar bolt. Move the generator away from the cylinder block so that the longest belt branch deflects by 10 mm when applying force to its middle with your thumb. Tighten the generator and tension bar mounting bolts.
