SECTION 7 : TROUBLE SHOOTING 

Fault Description 

Possible Cause 

Inspection (Fault Clearing) Actions 

7.1 Starter 

motor 

engaged 

but 

engine  will  not 
start 

1. No electrical power

1. Confirm  that  Terminals  1  &  2  are  connected  to  the  genset

battery, have normal voltage, and that polarity is correct.

2. MPU  fault  (failed,

disconnected,
installation
incorrect)

2. Disconnect  wires  from  Terminals  10  &  11.  Measure  the

resistance  between  the  two  wires.  It  must  be  between  10  –
1,000 

Ω

. If there is an open or short circuit then check whether

the wiring between MPU and the controller is open or shorted.

Directly  measure  the  resistance  of  the  MPU.  It  must  be
between 10 – 1,000 

Ω

. If there is a short circuit or an open then

change the MPU.

Measure the resistance between each pin of the MPU and its
metal housing. There should be no conductance at all. If there
is any conductance then replace the MPU.

During engine start confirm that the input voltage to Terminals
10 & 11 is greater than 1 Vac. If less than 1 Vac check the gap
between  the  tip  of  the  MPU  and  the  flywheel  teeth.  The
distance should be 0.037 mm to 0.127 mm.

3. Actuator 

fault

(failed,
disconnected, etc.)

3. If  the  two  items  above  are  both  normal  then  check  whether

Terminals 4 & 5 have a voltage output during cranking. If there
is  an  output  but  the  actuator  does  not  activate  then  check
whether the wiring to the actuator is open or not.

4. Actuator defective

4. Disconnect  the  wires  from  the  controller  to  the  actuator.

Confirm  that  the  wiring  is  not  shorted  and  also  has  no
conductivity to the housing of the actuator.

Connect actuator wires directly to the battery and confirm that
the actuator operates through its full range.

5. Other causes

5. With the engine stopped, manually toggle the actuator linkage

to see whether the action is smooth.

If that item is normal then manually toggle the actuator linkage
during  engine  cranking.  If  the  engine  still  does  not  start  then
check  whether  engine  fuel  supply  is  normal  (fuel  level,  fuel
valve closed, stop solenoid linkage, etc.)
