Only really been using the car properly in the last few days. Yesterday I found the new battery was dead.

I took it off the car and charged it up to about 12v. I then jump started the car, and checked the charge which was still showing 12v - so I presume the alternator is not working (and it does seem suspiciously noisy).

I checked the slam panel earth and battery leads to the alternator etc, and all looking in good order.

No battery light on the dash, but would my alternator diagnosis seem to be correct?

I would agree with you on that one, Paul.

It is probably leaking through the rectifier when the engine is not running.

To confirm diagnosis if you want to, unplug the alternator, reconnect the battery and leave it for a few days.

You could compare the battery drain (ignition off) with the alternator both in circuit and unplugged, to get a pointer towards an internal short.
Additionally if there was a 'hot electrics' aroma when the engine was driving the alternator, that also would suggest an internal fault such as a shorted diode in the rectifier.
Spare rectifiers are easily come by.

I think I am just going to swap the alternator and have a go at doing it myself. Never swapped one before. Anything to look out for?

Plenty of releasing agent on the adjuster bolt below the alternator!

Not required, we greased it when we had it :cool

10mm spanner is all you’ll require but to make life easier take off the stone guard which you’ll need a 10mm socket and a 6” extension bar.

I took the alternator off today. Never done this job before. Hardest bit was getting the undertray off as the bolts were threaded.

Alternator taken to the local engineers for a refurb as they had none in stock. 1 day turnaround, and it will cost £65.

Fitting on Friday all being well. Hope it goes well :bored
