Heading down to troubleshoot the generator on my uncles RV. Was running poorly and he had a guy come to the house on put on a new carb. After replacing the carb generator gets no power, stone dead. Guy looked for blown fuses and bad relays and came up with bubkis. Uncle got his money back and a new carb but has a stone dead generator.
Me and a buddy will try and trace it down. Obviously sounds electrical. Anybody out there familiar with these Cummings generators. Any advice will be appreciated.

Does it run without generating electricity or does it just not run at all?

Ya, everything was pretty general and the RV forums lead to dead ends.

Is it locked up? Can you turn it over at all?

Sounds like a dead start battery for Generator or start solenoid.

Had to knock a wire loose I would think. Changing a carb won't stop it from turning over.

I’m concerned that it locked up on you. Try to find a way to turn it over two complete revolutions, even if you can do it by hand
If it turns over then the next thing I would check is the starter.

If you can get it turning over with the starter and it doesn’t fire give it a LITTLE squirt of starting fluid and see if it pops or runs on the fluid. If it doesn’t then you could have a fuel or electric ignition problem.

Put another spark plug on a plug wire and see if you have spark
