low leg question

[potter]

Hi just found a lister petter dws4a with a marathon gen head at the dump. After getting it home it did not take long to get it up and running but no output from the head.
I found that one of the field windings was burnt so pulled only the one winding out and had to rewind with only 4 in hand 1 size wire up salvaged wire. Now my question
it seems to now put out ok except 1 leg is at 119 v and the second at 120 v will this be a problem for extended runs or load?
thanks for any thoughts.

PS this is at no load

Good find! Now, just where is this "dump"?  

What model Marathon head is it? I would think that running with a small imbalance would be OK as long as you stayed well under the rated capacity and kept a watch on temps in the windings.

Check the imbalance under load.  A few volts is nothing to worry about.  What a great find!

thanks  dieselgman  I don't have the head # in front of me its only one of the cheap 4 wire 30kva heads put together by pivot power.
Its overkill for my needs so will not be overloaded,  will only use it for the convince of the auto start  and running the few 240v tools in my shop.
the 4.5 kva 8/1 meets all my normal needs
finding this kind of thing at the dump is one of the joys of living on a small island in the Bahamas no repair shops, its quite common to find them

Weill I put about 4000 watt load on it the max I could come up with steady and it went rock stedy at 120.4 per leg so I hoping all is good after about 2 hours run the back end of the gen is cold the fan end is only slightly warm.

How sweet.  Nice work restoring the bum field winding!

Yes I have seen so many of these just go to waste over the years thinking it was such a daunting task to rewind.
 With the good results from this first try I think I will not let so many go to waste
It is a lot easier than I ever thought it was.
