First, take off the negative
Battery Cable to stay safe while working on the regulator. Secure and raise your vehicle, then taking out bolt 2 at the turbocharger brace 1. Unbolt bolt 1 from brace 2 and turn the swivel so it is on the side. Go ahead and take out screws 3 and 4, then remove wires 5 and 6. Lift off the cover over source 1 by undoing screw 2 and nuts 3 and 4. Unscrew parts 1, 3 and 4, then take out the voltage regulator 2 by pulling it out directly from the generator. If the condition of the commutator rings 1 is worn, you should replace the whole generator assembly. If the carbon brushes 1 seem worn, you may likely need to replace the generator assembly too. Before installation, ensure the carbon brushes 1 and commutator rings 1 are not badly worn. Attach voltage regulator 2 at the back of the generator and line it up before installing it slowly into the generator. Once screws 1, 3 and 4 are in, notch fit cover 1 back in place with screw 2 and nuts 3 and 4. Put eyelets 5 and 6 next to the generator studs and tighten on the + terminal screws, BUT, ONLY use the included nut 4, attached to the + terminal and tighten it to 18 N.m (159 in. lbs.) and nut 3 instead. First, place and tighten brace bolt 1 into brace 2 to 20 N.m (15 ft. lbs.), then install bolt 2 into turbocharger brace 1 and tighten it to 30 N.m (22 ft. lbs.). Drop the car, fasten the negative battery cable and make sure the charging system runs as expected.
