How to repair the self diagnostic fault indicator light of the generator set's electronic control device? When using the generator set for seasonal changes, the main spindle box and various lubrication surfaces should also be cleaned. The method is to use a mixture of engine oil, kerosene, and diesel as washing oil. After the engine oil is drained, add washing oil for cleaning. Wait for the generator set to run at low speed for 3-5 minutes, then drain the washing oil and add new engine oil.

The various fuel compartments in the fuel supply device should be checked for debris every 100-200 hours of operation, and the fuel tank and various oil pipelines should be thoroughly cleaned. When cleaning filters and seals, special care should be taken and any damage found should be replaced promptly. When changing oil during seasonal transitions, all spare parts of the entire fuel supply device should be cleaned. The diesel used should meet seasonal requirements and undergo 48 hours of precipitation purification to remove it.

When there is a fault in the electronic control diesel generator, the first thing to observe is the self diagnosis damage indicator light of the diesel generator's electronic control device. If this light is on during the operation process of the diesel generator, it indicates that the electronic injection diesel generator has a fault that the self diagnosis device can detect. The damage is generally related to the electronic injection mechanism. At this time, certain measures can be taken to retrieve the damage code stored in the computer and search for the cause of the fault based on the damage code.

If there is indeed a fault in the generator set, and the diesel generator damage indicator light on the dashboard does not light up when the diesel generator is running, it indicates that the diesel generator fault is a fault that the electronic control unit's self diagnostic mechanism cannot recognize. At this time, according to the traditional diesel generator, preliminary diagnostic results should be made based on the fault phenomenon, and possible causes of damage should be explained. In depth diagnosis should be carried out according to the principle of from outside to inside and from simple to complex. Remember that in this situation, the electronic fuel injection system cannot be dismantled or unloaded randomly. Only when the faulty electronic control device is determined, should the electronic control device be checked first. Otherwise, other parts should be checked first.
