Weak charging, a flickering charging control lamp or a generator that won't hold its voltage after the anchorage screws have worked loose – on the 122 with B18B the DC generator and its voltage regulator sit right in the vibration-prone part of the 12-volt system, and worn mounts affect both belt tension and charging.

This group includes the voltage regulator and generator together with the complete mounting kit: screw, nut plus wave washer and spring washer that lock the anchorage against the engine block's vibrations. When going through the charging system, the typical checks are the regulator's function, the generator's carbon brushes and that the anchorage screws haven't started to wander. Since corroded contacts and loose connections are a known weak point in the 122's electrical system, clean, firm mountings are a simple but important checkpoint during a restoration.
