15 K Centurian Generator- started during a power failure and shut down after 20 seconds or so. On restarting manually, saw sparks coming out of flywheel area just before it shut off. Local dealed replaced sth starter which had after repeated start attemps been damaged. It seems that the sames problem still exist . The engine starts fine but shuts down after a few seconds and we did see sparks again from the fly wheel area. The starter solenoid is staying engaged while the engine is running . Is this a n electrical relay problem or something worse?15 K Centurian Generator- started during a power failure and shut down after 20 seconds or so.

Check fuse and connections between start switch, control board, and starter solenoid.
ENGINE CONTROLLER CIRCUIT BOARD GENERAL: The engine controller board is responsible for crank- ing, startup, running and shutdown operations. The board interconnects with other components of the DC control system to turn them on and off at the proper times. It is powered by fused 12 VDC power from the
It is common to cut off the fuel supply by stopping the diesel engine to shut off the transmission of fuel or air. The method is to install the solenoid valve on the pipeline of oil or gas supply, and control the opening and closing of the solenoid valve by pressing the electric button. So the solenoid valve is out of control. It can't cut off the fuel and air.
More technology supports, suggest you to contact the Starlight manufacturer( diesel generator set), they supply Cummins, Volvo, Perkins generator and provide services supports, the email address: [email protected].
The buzzing sound is most likely the started solenoid chattering due to low battery voltage, change the battery and try again. If it still does it make make sure the engine is not seized and can turn over. Then measure voltage going from the solenoid to the starter, if it is very low change the solenoid
si tiene transfer automatico solo poner un swicht en hilo 1N para cortar senal de entrada al generador del utility power que sensa la presencia de voltage en caso de falta arranca el generador en forma de prueba
sound like a dead battery, or dirty / bad connection from battery- try jumping it with a car battery-- if that doesn't work, check battery connection, loose or corroded leads.. otherwise it is solenoid or starter or starter switch
throttle motor or governer board. or control board. your gas line could be to small. check the pressure while its cranking to see if it drops. watch the throttle to see if its moving while trying to crank the generator
Have you checked the fuse? Mine keeps blowing the fuse (located on the back of the control panel) with each startup and shutdown or use of idle control.
Typically caused by the fuel line (LP or Natural Gas) having a lot of air in it. Was your generator just installed, or was there any work done to the gas line of the building / generator? Consult local gas contractor / propane dealer / gas company for assistance in purging the fuel line.
A low battery can also cause this as well as the generator is not able to come up to starting speed quick enough. Try placing a stand alone battery charger on the generator and charge the battery. Also check the air filter as well.
OverCrank condition occurs when generator tries to start itself, or be manually started, and the starter spends too much time turning.
This can also indicate failure of the control board. This will need the expertise of generac technician. Call 1-888-GENERAC (1-888-436-3722)

Is the oil sump full? Has it been run with out oil? You can do an amp draw test on the starter. Should be 60 amps or so. Can you roll the engine by hand? If engine turns free pull the starter out and bench test it with jumper cables. Positive cable to cable lug and negative cable on the starter case. Hang on to it, lots of torque. If the stater turns slow or gets hot it is probably bad.
