Ensure the mounting bolts are tight — to preserve the connection between the motor and the flywheel. Both parts are under a lot of pressure, and a bad connection can cause them to wear out quickly. Inspect the flywheel — over time the flywheel can become cracked, worn or even lose its teeth, impacting efficient engagement with the pinion gear on the starter motor.

Carbon brushes and collectors are subjected to high loads and are more susceptible to faults than the alternator. While, for example, clamping carbon brushes in the alternator do not cause voltage to arise and thus relieve the alternator, clamping carbon brushes in the starter leads to the formation of significant arcs due to the high currents.
These arcs often destroy the collector. A multimeter and a clip-on ammeter are required for troubleshooting. Fault sources such as the pinion can, however, also be located through acoustic perception.
