Engine Will Not Crank - Perkins 1106D Troubleshooting Manual

58
Troubleshooting Section
Electronic Unit Injectors
1. With the engine speed at a fast idle, use the
electronic service tool to isolate one cylinder at
a time. Note if there is any reduction in engine
speed. If a reduction in engine speed is not noted,
the isolated electronic unit injector is not operating
under normal conditions. If the isolation of a
particular cylinder results in a reduction of engine
speed that is less than normal, this may indicate
that the electronic unit injector is operating below
normal performance.
2. Remove the electronic unit injector from the
suspect cylinder. Refer to Disassembly and
Assembly, "Electronic Unit Injector - Remove".
3. Install a new electronic unit injector. Refer to
Disassembly and Assembly, "Electronic Unit
Injector - Install".
4. Repeat the test in 1. If the fault is still apparent,
remove the replacement electronic unit injector
and install the original electronic unit injector.
Refer to Disassembly and Assembly, "Electronic
Unit Injector - Remove" and Disassembly and
Assembly, "Electronic Unit Injector - Install".

Recommended Repairs
Machine Security System
1. Verify that the correct keyswitch is being used.
Turn the keyswitch to the ON position.
2. Use the electronic service tool in order to check if
the 1639-09 Machine Security System is active.
Verify that the lamp for the machine security
system is on.
3. If the 1639-09 diagnostic code is active the
machine security system is armed. Deactivate
the machine security system and try to start the
engine.
4. If the engine will not start use the electronic
service tool to check for logged diagnostic codes.
5. Make repairs for all diagnostic codes. Ensure that
the repair has eliminated the problem.
6. If there are no active diagnostic codes refer to
the Troubleshooting Manual for your machine
application.
Battery Cables and/or Batteries
1. Inspect the main power switch, battery posts,
and battery cables for loose connections and
corrosion. If the battery cables are corroded,
remove the battery cables and clean the battery
cables. Clean the battery posts. Replace the
cables. Tighten any loose connections.
2. Inspect the batteries.
a. Charge the batteries.
b. Load test the batteries. Refer to Testing and
i02414534
Adjusting, "Battery - Test".
Starting Motor Solenoid or Starting
Circuit
1. Test the operation of the starting motor solenoid.
Refer to Testing and Adjusting, "Electric Starting
System - Test".
2. Check the wiring to the starting motor solenoid.
Starting Motor and/or Flywheel Ring Gear
1. Test the operation of the starting motor. Check the
wiring for the starting motor. Refer to Testing and
Adjusting, "Electric Starting System - Test".
2. Inspect the pinion on the starting motor and the
flywheel ring gear for damage.
Electrical Power Supply
Check the electrical power supply. Refer to
Troubleshooting, "Electrical Power Supply Circuit -
Test".
Internal Engine Fault
1. Remove the glow plugs. Refer to Disassembly
and Assembly, "Glow Plugs - Remove and Install".
