ELECTRICAL

Ground Test

The PDM uses pin N for a ground wire; it connects to the PDM through connector SSCB # 1. Check for
Test Procedure continuity between the brown wire at SSCB # 1 and the terminal block ground post. There should be
continuity to ground on the wire to pass.
What does passing
Wire harness and connections are acceptable.
this test indicate?
What does failing
Wire harness and/or connections are suspect.
this test indicate?

Static Stator Test

Disconnect the stator wire harness connector from the PDM. Measure resistance (Ω) between each of the
three yellow leads, for example: Y1 to Y2, Y1 to Y3, Y2 to Y3. Resistances should be 0.43 Ω ± 20%
Test Procedure
with no continuity to ground to pass this test.
What does passing
Passing these tests indicates the stator is operating normally.
this test indicate?
What does failing
If resistance values are not near equal on all three legs, there is likely a broken or shorted leg in the stator.
this test indicate?

Run Signal Test

The ignition switch must be turned to "ON" before completing this test. Disconnect PDM connector SSCB
# 2. Using a multimeter, check for continuity between the orange wire leaving this connector and the red/
Test Procedure
white wire returning to this PDM connector; there should be continuity to pass this test. There should be
no continuity to ground to pass this test.
What does passing The RUN Signal wires, harness and connections are functioning normally. Problem likely exists in PDM
this test indicate? or Main PDM connection.
What does failing
There may be a problem with the wire harness, switches, connections or splice block.
this test indicate?

Dynamic Stator Test

Place the unit in Park and start the unit. Disconnect the stator connection and measure the AC Voltage
from each stator leg. Separately test each leg of the stator by connection the meter leads to the wires
Test Procedure
leading from the stator (Y to Y/R, Y to Y/B, Y/R to Y/B). AC voltage output should be 17 VAC ± 25%
@ 1300 RPM, 40 VAC ± 25% @ 3000 RPM, and 65 VAC ± 25% @ 5000 RPM.
What does passing Passing this test indicates the stator is sufficiently supplying AC voltage to the PDM. If a charging system
this test indicate? problem exists, the cause may be the PDM, wire harness, battery, or fusible link.
What does failing Failing this test indicates there is a problem with one or more of the stator legs not providing sufficient
this test indicate? AC Voltage to the PDM. If a charging system problem exists, the stator or flywheel is likely the cause.
