Alternator Replacement
NOTE: Remove the alternator from below the vehicle.
'1. Make sure you have the anti-theft code for theradio, then write down the frequencies for theradio's preset buttons ('99 - 00 models).
2. Remove the battery negative cable, then disconnectthe positive cable.
3. Disconnect the 4P (or 3P) connector from the alter-naIor.

Rectifier Removal (cont'd)
Separate the rear housing from the stator/rectifier
assembly by removing the four screws and the ter-minal nut.
TERMINAL NUT
Unsolder the rectifier from the stator leads,. To avoid damaging the diodes with heat, pinch
the stator leads between pliers to carry heat off,and apply the soldering iron only long enough toseparate the leads from the rectifier.. Use a 100 W soldering iron.
STATOR SOLDERING
7. Install the new rectifier in the reverse order of removal.. Apply the soldering iron only long enough toensure a good connection so the heat will notdamage the diodes.
a Use only a rosin core type solder or solder joints
will corrode.

Rectifier Test
NOTE: The diodes are designed to allow current to pass
in one direction while blocking it in the opposite direc-tion. Since the alternator rectifier is made up of ninediodes, each diode must be tested for continuity in bothdirections with an ohmmeter that has diode checkinocapability; a total of 18 checks.
1. Check for continuity in each direction between- the B and P terminals.- the B'and P terminals.- E {ground) and the P terminals.
All diodes should have continuity in only one direc-UOn.
lf any of the diodes fails, replace the rectifier assem-bly, (Diodes are not available separately.)
