CONTROL MODULE TROUBLE SHOOTING
{
Problem
Possible Cause and Solution
Control module, DC on and charge fail • Check for battery supply on engine starter B+ (battery
light not lit, generating set will not start: positive) and battery negative using a voltmeter set to
read DC.
• Check for poor ground connections on all engine harness
black wires, switch the starter battery off to check
continuity to engine ground for all of these black wires.
• Check for battery supply on the engine harness 11 way
plug, terminal 4 (brown fused B+) and 6 (black B-).
Note: There are two small brown wires in this plug, check
terminal 4 connection only.
• Check for battery supply on module terminals 4 (B+) and
6 (B-) using a voltmeter set to read DC.
Generating set will not start, pre heat light • Pre Heat timer function is over timed, check the setting
illuminates (PSM720 only) screw on the pre-heat timer at the rear of the module and
adjust to approximately < 6 seconds maximum.
NB: Although the EPM72, RSM72 & LSM72 do not have a
pre heat warning light all modules do have a programmed
pre heat function and all will require the same fault check
process.
Generating set will not start, oil pressure Low oil pressure is not sensed, check oil pressure switch
light not illuminated: connections, refer to the relevant engine / module wiring
diagram/s within Section 5 Diagrams.
Generating Set starter motor turns but the Fuel solenoid not energising:
engine does not start: • Check wiring to fuel solenoid, blue/red to hold coil,
white/red to pull coil, (black to ground if required on
solenoid).
• Remove solenoid and check it is free to return to run
position.
• Faulty fuel solenoid, identify mechanical stop lever first,
this will have to be activated to stop engine. Then remove
the fuel solenoid to see if this allows the engine to run.
Stop engine and replace faulty fuel solenoid.
