When you test the motor have you pressed the start or are you testing it when it supposed to be off, some old machinery only had switching on 2 phase leave one phase energised and also O/L motor protection can be found on 2ph only, it can be a number of reasons why your getting your readings and without knowledge and experience you need to leave well alone, you'll be surprised how fast not knowing what your doing can escalate the costs and most of it probably caused by yourself not following procedure for checking and testing motors and control circuits.
It would probably take me less than 5 minutes to test and identify the issue while not causing any further damage but this is because this is what I do for a living ... sometimes enjoyable and others not (-4 degrees monday morning at stone yard chipping ice out of a pump I dismantled comes to mind)...
I would in your case put it back as found and advise to call in someone experienced in this field because I see the problems caused by curious sparks trying to solve these problems and it usually isn't pretty and can be costly to said sparks after I've done a report.
I would need to be onsite to resolve this for you as its very difficult to advise on the forum only .... what I find will denote the actions and tests I carry out.
PS when you here the motor buzzing you could be causing damage to it which may require a rewind or new motor whichever may be most cost effective.
Edit just noted you said your not getting involved any further ...
