Is the warning light working ? It needs it for the regulator to start charging. What size pulley does it have and does it charge more when revving ? Does it change with the temp sensor wire disconnected ?

According to the words and music the top terminal with the insulator pushed over it is for a tacho, the larger bolt terminal next to the three spades is B+ as are the two larger spades , the smaller spade next to the two large ones is ign light, the small spade inside the case at about five oclock is low voltage computer feed, and the orange is a charge sensing which should go to the battery. If its not charging poke a live onto the small spade next to the two large ones and it should start to charge, if it does not the alt is juckered.

Has your 7600 got an external regulator fitted under the bonnet, behind the battery  in front of the diesel tank, 

As the alternator in the picture has a built in regulator, which was fitted to later models 10 series 

This is the type fitted to my old ford's

Warning light works, pulley is same as old, makes no differences how many rev's, and no change with sensor wire off. 

Which is pointing to duff new alternator.

Looking that way, will the supplier swap it? 

[woody paul]

Thanks to everyone for there help. Turns out that supplier has had problems with them and there supplier has flagged up a recalled on them so may get a exchange or money back.
