If I decipher your message correctly (and I'm not sure I do) you are getting
a lower reading with the engine running although the difference of 20mV is
negligible. Looks like your alternator is not charging. Could be brushes,
rectifier, broken fan belt, faulty feed to the field coil.

Of course knowing the car may help a bit too.

If you are the Chris in Addlestone, you could get Roy Auto Electrics in
Hetherington Road, Shepperton (01932 770136) to look at it. I have found
them very good in the past.

 

I have spoke to then today. and they have told me to bring it over to
them and they can rebuild it for me, but in the meantime i went out last
night and sprayed it all with WD40 started it ok first thing and have
got volt meter on it and it has been 13.5 volts all the time i am
driving,drops to 13.0 volts when sitting at lights etc.like they said
keep a eye on it ..
once again thanks for the replys..chris.
