Alternator - B + Terminal Repair
89Mitsubishi07SUBJECT: PRECIS MANDO ALTERNATOR B +
TERMINAL REPAIR
NO. TSB-89-16-005
DATE September, 1989
MODEL Precis
PURPOSE
This bulletin describes parts available to be used when repairing certain Precis Mando alternators if the B + terminal is damaged at the alternator.
DESCRIPTION OF CHANGE
The Mando alternator used on Precis vehicles built before February 1989 utilized a 5 mm diameter B + (main output) terminal bolt. Units built after that date use a 6 mm diameter lug. If you are repairing a Precis Mando alternator built before February 1989 because the B + terminal has been damaged from high current flow, a kit of parts is available to replace the 5 mm bolt with a 6 mm lug. A new B + wiring assembly is also available with a 6 mm inside diameter terminal eye.
Do not repair the existing wiring harness by soldering or crimping on a new terminal. Do not ream out the 5 mm eye to fit the new terminal.
REPAIR PARTS
Use the following part numbers to order the 6 mm lug kit or B + wire.

Figure 1:
Figure 1 below shows the repair parts for the alternator and their location.
When replacing the alternator B + plate, be careful not to overheat the diodes in the rectifier assembly, as they can be destroyed by the high temperature used when soldering.
When you install the 6 mm lug kit, you will need to install the new B + wire.
Torque the new retainer nut to 5.9 - 7.8 N-m (4.3 - 5.8 ft.lbs.).
Torque the new terminal nut to 4 - 6 N-m (2.9 - 4.3 ft.lbs.).
Figure 2:
Figure 2 below shows where the new B + lead must be installed.
Disconnect the Negative battery cable at the battery. At the alternator, cut off the end of the old B + lead, cover the end completely and securely with electrical tape. Route the new B + lead along side of the old B + lead using care not to damage the insulation or connector when bringing through body holes. Make sure the new B + lead is not pinched or routed against sharp objects. Strap the new B + lead to the existing B + lead with tie-wraps. Cut off the end old B + lead at the fusible link terminal end and cover the end securely with electrical tape. Connect the new B + lead to both the alternator and the fusible link box, making sure the terminal studs are covered by the insulating cover of the new B + lead. Secure the new B + lead to the old one with tie wraps.
IMPORTANT:
Test the charging system thoroughly after repair.
