Q: How do you replace the Voltage Regulator of lAR-type alternator on Lincoln Mark VII?
A: To remove the alternator, set it on a clean workbench. Then, remove the four voltage regulator mounting screws to detach the voltage regulator/brush holder assembly. Lift the assembly from the alternator and detach the rubber plugs. Remove the brush lead retaining screws and nuts to separate the brush leads from the holder. Note that the screws have Torx heads and require a special screwdriver. After noting the relationship of the brushes to the brush holder assembly, remove both brushes, being careful not to lose the springs. If installing a new voltage regulator, insert the old brushes into the brush holder of the new regulator. If installing new brushes, insert them into the brush holder of the old regulator, ensuring the springs are properly compressed and the brushes are properly inserted into the recesses in the brush holder. Install the brush lead retaining screws and nuts. Insert a short section of wire, like a paper clip, through the hole in the voltage regulator to hold the brushes in the retracted position during regulator installation. Carefully install the regulator, making sure the brushes don't hang up on the rotor. Install the voltage regulator screws and tighten them securely. Finally, remove the wire or paper clip and install the alternator.
