Glad you are not stressing over it life goes on. I think if it were me I would have an electrician see what he or she could find. Problem with having a generator person or well person is they are experts in those specific areas. It sounds like an electrical problem somewhere so I would hope an electrician could find it.

 

Disconnect the feed to the pump and start the generator. If it keeps running and no fuse blows you'll know it's on the pump side. It it does it's the generator.
From the pic that's a deep well submersible pump. It could be your water table is down and the pump overheated. Every pump company I know does both the electrical and the mechanical. Your person should have diagnosed it the first time. How do you keep your cistern from freezing in the Winter? Do you drain the system?

 

That's a great idea. I need to talk to my generator guy and the well guy. For all I know the well guy did test the amps. The well guy probably knows how to do that, too.

The biggest obstacle is finding qualified tradespeople. The closest town is Ridgecrest and it survives mainly due to being the home of the Naval Air Weapons Station China Lake.

 

Yes, we did disconnect the feed to the pump and the generator won't stay running. I do drain the line in the winter. It is deep. I'm not sure but I think it's 200 to 300 feet. The water table is not low.

 

Did you stick the tank? It may be sludge in the tank that is causing the unit to shut off. Next check the fuel filter and the injectors. There is an auto shut off if the oil is low but that should show on the idiot lites.

The Kubota is in great running condition as per the man (Jim ) who worked on it. I don't know jack shit about it but he does.

Jim wrote: "My thoughts are that the regulator failed and the voltage dropped. That would cause the amps to go up and blow the fuse. The well guy (Phil) ran the well and it was fine, so probably not the well. Hard to know what really happened."

I texted back to Jim, to go ahead and order the Kubota brand voltage regulator and not a much less expensive Chinese knock-off.
