Analysis of Volvo Generator Set Failure to Start Normally

Sep. 25, 2021

Volvo generator sets may occasionally fail to start during daily use. There are many reasons why the generator cannot start. At this time, the relevant crew operators must not blindly operate, and they should call the professional manufacturer’s repair telephone in time for consultation. If it still fails to start normally under the guidance, it is necessary to arrange relevant personnel for on-site inspection and repair. In this article, Starlight Power Generation Equipment will introduce in detail the main reasons why Volvo generator sets fail to start, for your reference.

(1) Check whether the battery voltage reaches the rated voltage of 24V

Because the Volvo generator set's generator is usually in an automatic state, the electronic control module ECM monitors the whole set status and the communication between the EMCP control panel is maintained by the battery. When the external battery charger fails, the battery power cannot be replenished and the voltage drops. At this time, the battery must be charged. The charging time depends on the discharge of the battery and the rated current of the charger. In an emergency, it is generally recommended to replace the battery.

(2) Check whether the battery terminal and the connecting cable are in poor contact

If the electrolyte of Volvo genset battery is replenished too much during normal maintenance, it is easy to overflow the battery surface and corrode the terminal, which increases the contact resistance and makes the cable connection poor. In this case, sandpaper can be used to polish the corroded layer of the terminal and the cable connector, and then re-tighten the screw to fully contact it.

(3) The positive and negative cables of the starter motor are not connected firmly

Volvo generator set starter motor failure is less likely, but it cannot be ruled out. To judge the action of the starter motor, you can touch the starter motor shell at the moment of starting the engine. Or the starter motor is severely hot and has an irritating burnt smell, and the motor coil has been burned. It takes a long time to repair the motor and it is recommended to replace it directly.


(4) There is air in the fuel system

This is a relatively common failure, usually caused by improper handling when replacing the fuel filter element of the Volvo generator set that caused air to enter. After the air enters the pipeline with the fuel, the fuel content in the pipeline is reduced, and the pressure is reduced, causing the engine to fail to start. Exhaust treatment is required at this time.

The above four points are the analysis of the reasons why the Volvo generator set cannot be started as summarized by Starlight Power Generation Equipment. However, the actual specific situation needs to be analyzed in detail and flexible. No matter how much theoretical knowledge is only for reference, it is not a thorough analysis by our manufacturer. Therefore, when problems are found, you can call Starlight power generation equipment in time, and we will serve you wholeheartedly.
