Possible Cause and Solution
• Check solenoid hold relay, please refer to image 69.
Temporarily swap this relay with the pre heat relay, try to
restart the generating set after resetting all shutdowns. If
the generating set now runs, replace the faulty relay with
a new relay. Or
• Measure DC voltage on relay blue/red hold wire. Best
practice is to inhibit the generating set engine from starting
by temporarily removing the red/white connection from
the starter solenoid, then follow the normal start-up
procedure, through engine pre heat, fuel solenoid energise,
to solenoid hold state. At this point there should be 12v
measured on the hold wire for the engine to continue
running after start-up. If the voltage is correct, replace fuel
solenoid with new.
Insulated Return Relay Panels will be mounted
in the following areas:
Insulated Return
• No fuel, check the fuel tank/level and that the fuel cock is
turned to the on position.
• Air in the fuel system, vent air, please refer to 'Bleeding
the Fuel System'.
• Water in the fuel, change the fuel filter and bleed the fuel
system.
• Fuel filter clogged, change the fuel filter and bleed the
fuel system.
• Fuel lift pump (if fitted) blocked, remove, replace and
bleed the fuel system.
• Fuel return not fed back to tank, re-route fuel return pipe.
