If the generating set doesn’t put up the demanded performance after having been started as prescribed and having reached the right engine speed, you will have to check the following points:

1.  check if the engine speed is high enough and if it remains stable
2. disconnect all the loads, so that the generating set can work without any load
3. check if the cables and plugs are damaged
4. check if the connections are correct and if the capacitors have enough power
5. check if the sockets and the fuses are damaged
6. check if the stator’s windings are connected properly
7. check if there is a short circuit in the stator windings
8. carry out the maintenance of the engine
