Thanks, will probably arrange to get it moved to inspect properly. Engine good anyway.

The generator is a Mecc Alte ECO28-VL4. It is a 12 wire system. It is a Stephill generator but cannot find their model number on it. I can work on it no problem and have good test gear. UK location so 240v and 50Hz.  I have had a quick look at it and there is 220v between L2-N and L3-N. the 240v output is from L1. The owner only used it for a 3-phase supply but he now has a mains 3-phase supply fitted so the generator is no longer required. I would only be using it for 240 supply. My concern is that if one of the windings for L1 has broken down, will using it and taking the 240v supply off L2 or L3 make it unstable. Also a concern is that the 110v supply for the regulator is from the fields on the L1 supply so that will also have to be moved to the L2 field. For me to investigate it properly I will have to get the unit moved to where I can take it apart under cover to trace the exact location of the problem. There is a voltage selection switch and I suspect that the problem may be in that. Not quite sure of the exact reason for this switch as in other generators with only 3-phase and a single 240v output they have no switch.  There is a considerable cost to get it moved as it is mounted on a skid base so requires a forklift to move it on and off a trailer so to do this I want to be sure I will get some use out of it.

A friend has a generator where one phase has stopped working. The phase not working is the one supplying the 240v output. The 3-phase does not work. If the 240v outlet is switched to one of the working phases to supply 240v, will running the generator like this cause further damage? 3-phase not required
