STEP 5.
Check for 24 Vdc at each terminal of R4 Shunt and ground.
STEP 6.
If voltages are not present, replace R4 Shunt.
STEP 7.
Check for 24 Vdc at each terminal of diode D1 and ground.
STEP 8.
If voltages are not present, replace diode D1.
STEP 9.
With DEAD CRANK SWITCH in CRANK position, check for 24 Vdc at terminal 3
of the starter motor magnetic switch (SMMS) relay and ground.
STEP 10.
If voltage present, check for ground at terminal 4 of the SMMS relay.
STEP 11.
If voltage is not present, check for 24 Vdc at TB5-5 and ground.
STEP 12.
If voltage present, check wiring or replace Battery Disconnect Switch (WP 0049).
STEP 13.
If voltage is not present, check wiring or replace DEAD CRANK SWITCH
STEP 14.
Check for 24 Vdc at pinion solenoid terminals 23A10 (+) wire and black jumper
wire (-).
NOTE
It may be necessary to remove cover from pinion solenoid to access solenoid terminals.
STEP 15.
If voltage is not present, check wiring or replace SMMS relay (WP 0055).
STEP 16.
If voltage is present, check cable at starter or replace starter (WP 0076).
NOTE
When completing CID 444 FMI 12 (WP 0009) do not reinstall fuse A1F4.
STEP 17.
On EMCP set ENGINE CONTROL Switch to MANUAL START. If engine does
not crank, go to Generator Set Control (GSC) fault isolation for CID 444 FMI 12
STEP 18.
Set ENGINE CONTROL Switch to MANUAL START observing the following
conditions:
a.
Engine crank indicator K4 will appear on lower display of GSC for the
time duration (in seconds) described by setpoint P017.
b.
Engine crank indicator K4 will extinguish for the same duration.
c.
Engine crank indicator K4 will appear again for the P017 duration.
d.
Cycle will cease when time exceeds P018 duration (in seconds).
STEP 19.
If engine crank indicator K4 does not appear and extinguish properly, replace
STEP 20.
Verify the problem has been resolved.
