has been working, check out, where is the problem, continue to work will have an impact?The current voltage is 24. 5V. 27V is up and down now
I suggest you use the multimeter to test the generator's voltage and see if there is any problem with the generator. If the above inspection does not have the unusual, must ask the specialized maintenance to help you to solve the problem.
As you say, there may be a problem with the silicon rectifier or regulator! You cannot boot if the battery voltage is low.
The battery voltage of the excavator is usually 24V and the generator voltage is 28V.
