Fig. 7.22. Check of the relay regulator of tension

Using an ohmmeter, check conductivity between F and B diodes (fig. 7.22).

ATTENTION When positive and negative poles between clips of F and V are connected in a uniform chain, conductivity has to be only in one direction. If the continuity is in both directions, perhaps one of diodes is punched. In this case replace tension regulator.

Using an ohmmeter, check conductivity between diodes F and E.
