Problem in DG Set

Could be your voltage regulator.

Could be a blown fuse.

Could be there's no D in the G's FT.

Could be a loose wire somewhere.

Could be you haven't got anyone skilled enough to maintain it and diagnose the fault. After all, instead of getting someone to fix it, your breakdown plan is to ask a bunch of unknown strangers on the internet to make wild guesses without being able to see it. Totally bizarre. I don't even know what make it is! Tell me, have you spoken to the manufacturer yet, and talked it through?

The electron fairies have got lost in the system.
They could have been kidnapped by the overload ogre. There's so many gremlins out there it's hard to say which to lay the blame with.

and people wonder why I detest ANONS
