Question about Pramac Electrical Supplies
The air duct is blocked by dust and the ventilation is poor, which makes the heat dissipation of the generator difficult. The dust and oil dirt in the air duct shall be removed to make the air duct unobstructed.

Start looking at your safety circuits.
1. High water temp
2. Low Oil
3. Low water etc...
From the manual these are the protection circuits.
• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.
Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)
Once you isolate which circuit it is in then you can chase wires or change the bad switch.
Thanks for choosing FixYa.
