1 Starter motor brush renewal is a relatively difficult procedure, requiring skill in the use of a soldering iron. It should also be borne in mind that if the starter motor has been in service long enough to wear the brushes out, the rest of the unit is likely to be well worn also. In such a case the best course is to obtain a new or reconditioned starter motor.
