strangely enough i was looking at the alternator on mine yesterday,as i only ever get 13.9 volts charging,wondered if it needed replacing, on inspection mine is fitted with a Valeo alternator?,in a sudden eureka moment i realised i had one in the shed that i bought brand new 3 years ago,on ebay,as it was cheap for an omega 2.5td,never fitted it, so i compare it to the rr one and its exactly the same as the one fitted to my rangey, same fixings same connections etc etc, so now im wondering should i just fit it and see what happens?
