Battery + Test
Protected Battery + Test
Ignition Switch Test
BAT + Test
Test Procedure
1: Complete the Battery Voltage and GROUND Tests
; note your results. Disconnect PDM connector
SSCB # 1 and check for DC Volts on the red wire entering pin H at the PDM. The voltage should be at
or near Battery Voltage
.
2: Check the resistance of the red wire between the battery and PDM connector SSCB # 1. There should
be no open leads or shorts to ground.
What does passing
this test indicate?
Wiring harness, connections and fusible link between the PDM and the battery are good.
What does failing
this test indicate?
A: There may be a wire in the main harness that is broken or shorted to ground.
B: There may be a damaged fusible link.
C: There may be a bad wire connection at the starter solenoid.
PROTECTED BAT + Test
Test Procedure
The ignition switch must be turned to the "ON" position before completing this test.
1. Complete the BAT + Test
an d not e your res ults .
2. An Orange wire exits the PDM on pin M in SSCB #2. Check for DC Volts on this Orange wire at the
ignition switch; the voltage should be at or near BAT + voltage
to pass.
What does passing
this test indicate?
1: The PDM is supplying the correct amount of protected battery voltage to the orange wire.
2: The wiring harness and connections are good.
What does failing
this test indicate?
1: The PDM may not be receiving a RUN signal from splice block 1 on Pin B on SSCB #2.
2: If voltage at the orange wire entering the ignition switch differs significantly from BAT +
voltage, there
may be a problem in the wiring harness or PDM.
Ignition Switch Test
Test Procedure
The ignition switch must be turned to the "ON" position before completing this test.
1. Check for DC voltage on the red/white wires leaving the ignition switch; the voltage should be at or
near PROTECTED BAT +
voltage to pass.
What does passing
this test indicate?
The ignition switch is good.
What does failing
this test indicate?
If voltage at the red/white wires is significantly different from the orange wire, the problem is most likely
in the ignition switch.
