Make sure your battery light comes on when ignition is switched on I am guessing it won't and this is why the there is no charge, and it's not uncommon for the blue wire to break.
W is not used this is for rev counters on diesels and for electric chokes.

As suggested I took the push on connector off and it appears to have corroded slightly - i have cleared the wire back to a good bit and reconnected using an "o" ring terminal and wired and refitted and all appears to be good.
Battery reads 12.96v when engine off and 14.22v when engine running and does not drop when engine revved so fingers cross problem appears to have been solved.
Thanks Martin and everyone else for their advice - saved me £70 for a new alternator that in the end was not the problem.
thanks again
