Onazn genset suddendly dead

[tudorsailor]

Went to start the Generator which is a MDKBH. I pressed prime first as I always do before starting. It primed but then went dead. Nothing in the remote display.
Battery is 12.8v. Oil is full. Sea cock is open. No change in breakers but flicked them both ways. No flashing lights. No different on genset itself

Could this be a PCB failure?
Can I do anything else to find the problem

Thanks

Did the displays come on after prime and b4 it started in the past ?

Yes, when pressing g prime the hour display works. This time it worked and then went dead

Multimeter on the power input to the gennie
if you’re lucky the supply failed

Check/change all the relays under the cover usually there's two, plus the duetch plugs of which there's loads! Unplug plug in again before you do anything else!

Fuel issue? Change filters?
