Please check the diesel and lubricating oil. When the generator is static for a long time, the various materials of the unit itself will have complex chemical and physical changes with the oil, cooling water, diesel oil, air,which will cause hidden but continuous damage to the genset.
Please check the solenoid valve. When the unit is running, you can check by watching, listening, touching, and sniffing. When starting by listening, press the start button for three seconds to start. During three seconds of startup, two clicks can normally be heard. If you only hear the first click but not the second, you need to check whether the start solenoid valve is working properly.
Please check the battery .Battery maintenance is a key determinant of the normal start-up process of the generator. When there is a problem with the battery , there will be a "voltage without current" . In this case, you can hear the sound of the solenoid valve in the starter motor, but the coupling is not driven. The battery fails to stop due to the battery charge is stopped when the test machine is tested, which leads to the battery power shortage. There is also a situation that may be ignored is that domestic batteries have a short life, about two years or so. This situation may also occur if you forget to replace them regularly.
