Installation
We install the voltage regulator in the reverse order of removal. Before installing a voltage regulator that is in operation, inspect the brushes and make sure they are mobile. If the brushes are broken or badly worn (protrude from the brush holder by no more than 5 mm), or they get stuck in the brush holder, the regulator must be replaced.
