Thinking about it - I'm not sure just 'what' the geny was using for
'earth'.... no ground spikes that I could see.... don;t know what's
the usual arrangement in these circumstances

In theory the generator chassis should be connected to one of the
alternator phases and that point also connected to the real earth via a
spike. But there are also arguments for having both phases floating wrt
real earth. What is "best" really depends on the individual circumstances,
how things are switched/protected and the existance or not of an RCD.
