8 Connect the positive lead of a multimeter set to measure voltage to the battery negative post.
9 Connect the negative lead of the multimeter to the generator housing.
9 Increase the engine speed to approximately 2500 r.p.m.
10 Record the voltage reading.
11 Reduce the engine speed to idle.
12 Check the two readings. If the readings exceed 0.3 V, there is a high resistance in the charging circuit.
13 Trace the cause and correct the problem, refer to 8A Electrical Body and Chassis.

4 Major Service Operations
4.1 Generator
Remove
Refer to 1.2 WARNING, CAUTION and NOTES
before disconnecting the battery.
1 Disconnect the battery ground lead P-5. Refer to 8A Electrical Body and Chassis.
2 Insert a ½ inch drive socket bar into the tensioner arm and rotate the tensioner arm clockwise.
3 Remove the drive belt from the generator pulley and release the tensioner. Refer to 6A1 Engine Mechanical – V6 for further details as required.
4 Pull the battery harness cap back from generator terminal P-9 (3), remove the nut (4) and remove the
positive lead (2) from the generator (5).
5 Disengage the connector retaining clip and remove the connector E-4, (1) from the generator.
Figure 6D1-1 4
6 Remove the three bolts (1, 2, 4) retaining the generator (3) to the generator bracket.
