Give you some suggestion, hope can be helpful for you.
Here is some basic principles for troubleshooting generator faults:
1. Check outside of generator firstly then inside
In the case of generator failure, the possible fault locations outside the electronic control system should be checked firstly. This can avoid a fault that is not related to the electronic control system, but make complex, time-consuming and laborious checking on the sensors, computers, actuators and circuits of the system. The real fault may be easier to find but can not be found.
2. Code priority
Electronic control system generally has fault self-diagnosis function. When some fault occurs in the electronic control system, the fault self-diagnosis system will immediately monitor the fault, and alarm or prompt the operator through warning lights such as "monitoring engine". At the same time, the fault information is stored in code. For some faults, the fault code should be read according to the method provided by the manufacturer before the fault self-diagnosis system is checked, and the fault location indicated by the code should be checked and eliminated. After the failure code refers to the elimination of the fault, if the engine failure phenomenon has not been eliminated, or no fault code output is started, then the possible fault location of the engine is checked.
