It should beep, or give a really low reading as its as close to a short circuit as your likley to get.

Failing that, measure the potential difference between the cars body and the output of the alternator. Also, not sure on a DET engine, but I would imagine it will have a second smaller wire which controlls the regulator, check that is firmly connected, or else it wont charge the battery.

Sounds to me like your alternator is dead to be honest.

Edit- Apparantly I should read the whole post before replying, sounds like youve got it all in hand.

lol! - No, it's all good - I appreciate the help, and between what you and Pukka are saying, I think I'll re-check my wires *just in case* I've missed anything, before I decide to shell out £88 for another!...

The tip about the wire to the regulator sounds promising - I 'll check if I have one, and if so, if it's connected!

Cheers guys,


Den.
