Thanks for the replies. im definitely going to repair it though. (agricultural engineer by trade) i dont think ive ever had to buy an aletrnator. you can get regulator, rectifier, brushes and bearings for £20 and with all that and cleaned up slip rings theres not much else to go wrong  8) I was really wanting to see if people were certain on an alternator fault rather than wiring. Loving the scrap it comment  ;D Cheers, James

Thanks both for your replies. Ill go up this weekend  then and do some more testing  :) Thanks again, James

Ill probably get slated for this post, but ill give it a go. I have a mate with a MG BGT ??) And the ignition warning light stays o. while running. Although it does get dimmer when running/revved up. The bulb is the same bulb as before the problem occurred. The battery seems charging fine. 14v + at battery when running. I do need to do a test with all the lights etc on. With the ignition on there is 12v coming down the small brown wire from the light. The connections are all clean, emeryed them up WD40 and reassembled. I have a feeling that the alternator could do with a rectifier/diode pack putting in it but could anyone give any suggestions. Cheers, James
