Just a wee query to those in the group who know more about these things than I do. I've been fitting a 12V winch to my Discovery. It was causing me problems which I've traced to a dodgy relay. However, my question concerns the reading of 15.6 volts I was getting with the engine running. This seems a bit high to me. I thought it should have been nearer 14 volts. Any advice on whether this is normal or a problem would be appreciated.
Thanks Davy M.
