3. Move the drive lead from pin A (F-) to pin F (F+)
in the harness plug. The DMM must show a
very high resistance. If the ohmmeter shows
less than 100K ohms, the field coil is grounded.
Replace the field coil.

STATOR TESTS
These alternators have delta-wound stators. Test 1
will show the condition of the phase lead from the
ring terminal at the diode end of the lead to the sol-
dered connection at the phase winding. Test the
phase coil windings on a bench stator tester, follow-
ing the tester's instructions.
Before performing tests:
1. Check the stator for signs of damage, such as
burnt insulation or a loose coil.
2. Disconnect the phase lead wire from the mount-
ing terminals.

Stator Test 1: Check For Stator-To-Stator Conti-
nuity
1. Set the DMM to the ohms scale and zero the
meter.
2. Connect one meter lead to phase lead P1 (Fig-
ure 10-15), connect other meter lead (one at a
time) to each phase lead P4, P5, and P6.
Repeat for P2 and P3.
3. The DMM must show OL (out of limits) each
time. If the DMM shows a value, replace the
stator.
