The Reason Why The Diesel Generator Starter Does Not Rotate

Mar. 25, 2022

Why does the diesel generator have the problem that the starter does not rotate? This kind of fault is generally caused by insufficient battery power or poor circuit contact. The internal open circuit of the engine and the poor internal contact of the electromagnetic switch can also be the reasons.

When checking such faults, the components that are easy to find in the diesel generator should be checked first. The specific methods are as follows: Check whether the power of the battery is sufficient. Note: The fusing current of the starting fuse is generally 30A or 60A. Use the multimeter DC voltage to measure the no-load voltage of the battery and the voltage at startup. If the difference between the no-load voltage and the voltage at startup is large, it means that the battery has insufficient power or there is an internal fault; if the difference is small or basically the same, it means that the battery has sufficient power. The next step should be to check the electromagnetic switch and DC motor.


Use a medium screwdriver to short the battery terminal of the solenoid switch to the switch terminal. If the electromagnetic switch is closed after the short circuit and the DC motor is running normally, it means that the fault is in the starting circuit other than the electromagnetic switch. If the electromagnetic switch does not pull in after the short circuit, it means that there may be an open circuit inside the electromagnetic switch or the DC motor.


Then use a screwdriver to short the battery terminal bar and the field terminal. If the DC motor can run normally, it means that there is a fault inside the electromagnetic switch. If the DC motor still does not run and no sparks appear during the short circuit, it means that there is an open circuit fault inside the DC motor; if there is sparks, it means that there is a short circuit inside the DC motor, and the current motor should be removed and repaired.
