I am trying to find the cause of a battery drain on my 2003 TD5 defender.
I have read a lot about a diode failure in the alternator as being a possible cause, but I am not sure how to test this?
I have removed the main cable from the alternator and this made no difference to the battery drain, however there is a small multiplug that plugs into the back of the alternator and I am having difficulty in getting to it to remove it to see if this could be causing the battery drain.
So what I need to know is if the alternator has a faulty diode, would the current drain back via the cables on the multiplug or the main alternator cable??
If it could be via the multiplug, any suggestions as to how to easily access it?
The size of the current drain is about 350mA if that makes any difference?
