TROUBLESHOOTING
If you have used your generator for some time and find you cannot start it or it
shuts off automatically, it is usually caused by failure fuel system such as
running out of fuel, non-energized solenoid, and burned solenoid or by failed
remote control unit. If there is no 12VDC power to solenoid, please
troubleshoot as follows:
1. Check whether solenoid fuse blows out or not. If it blows out, replace it.
2. If solenoid fuse is fine, please directly use a copper wire to feed 12V to
solenoid (when disconnect blue wire to solenoid, make sure electrically insulate
it for avoiding short circuit) and crank engine, see whether you can start it or
not. If it works, solenoid control board or remote control unit fails.
CAUTION: there is a blue wire connected to the top of solenoid, NEVER touch
the blue wire to engine case while with battery hooked up! Otherwise, a fuse or a
control board for solenoid behind control panel will be burned!
Table 5- Causes and troubleshooting for the engine not being started
Air exists in fuel system
Release trapped air in the fuel hose.
Preheat cold air using glow plug first,
then crank engine.
Fill machine oil into crankcase after warming up.
Fill machine oil into inlet pipe.
Remove the connection belt from the
machine(tapered shaft only), start the
engine and then stop it. When it is
warmed up, assemble the belt and
then restart the engine.
Check solenoid and see whether it is
energized. Check fuel injection pump.
Clean fuel tank, fuel filter and fuel pipe
and change the fuel.
The fuel get thickening and can't flow
easily
Use prescribed brand fuel
Injection fuel is little or the spray is not
excellent
Check the position of governing handle or
check and clean the fuel nozzle, change fuel injector
if necessary.
Mainly by ill spray
Incorrect delivery angle
Leakage in gasket of cylinder head
Deficiency in pressure of compression
Interrupted of diesel fuel
Run out of fuel and get air in the fuel hose, should
refill fuel into the fuel tank and drain fuel hose freely.
Fuel pipe leaks or fuel filter is obstructed.
