In dismantling the alternator, remove the alternator and place it on a clean work bench. The next step is to remove the nut, lock-washer, pulley and the four small bolts situated behind the pulley. Next, take four big bolts which fasten the front cover to the rear housing and loosen them. Then remove the stator, the two bolts that attach the brush holding assembly, and the nut behind the rear housing that has the retainer. In case of replacing the brushes, the length of each brush available is measured and compared with the required minimum length; in case one of the brushes is shorter than the required minimum, change them. Make sure that every brush slides in the brush holder. In case of component check, check the continuity of the two slip rings, where resistance should be 3.5 to 4.5 ohms. Probe between slip rings and the rotor, and ensure that continuity is not present. Should one of the rotor tests fail or should the slip rings be worn out too much, it is flawed. Check also continuity between one end of one stator windings and the same end of the other, when open, stator is faulty. Also, inspect a grounded stator winding between each stator terminal and the frame. Test the rectifier with an ohmmeter to ensure continuity and change it in case it fails any tests. To put back together, assemble the parts in the same order they were removed, but be sure to press down each brush using a small screwdriver, this way the brush holder can be fitted.
