  Q: How to repalce the Voltage Regulator on Ford Focus?

  A: The following procedure is for the Magneti Marelli unit installed on the project vehicles - the procedure is essentially the same for any other Alternators that may be installed on other models. The manufacturer does not recommend rebuilding the alternator yourself. Make sure that new brushes and regulator are available before dismantling the alternator. Remove the alternator from the vehicle and place it on a clean workbench. Remove the four securing nuts, and withdraw the plastic end cover from the alternator. Unclip the plastic cover at the center from the brushes. Remove the voltage regulator/brush holder mounting screws and nuts. Remove the regulator/brush holder from the rear of the alternator housing. Measure the exposed length of each brush. if less than 3/16-inch(5 mm), replace the assembly. Make sure that each brush moves smoothly in the brush holder. Check that the slip rings - the ring of copper on which each brush bears - are clean. Wipe them with a solvent-moistened cloth; if either appears scored or blackened, take the alternator to a repair specialist for advice. Installation is the reverse of the removal procedure. Install the voltage regulator/brush holder, ensuring that the brushes bear correctly on the slip rings, and that they compress into their holders. Tighten the screws securely. Install the rear cover, and tighten the screws securely. Install the alternator.
