SupporterHi All
I have just ordered a 100amp Marelli alternator for my 300tdi Defender.
Anybody had any problems with these? I have a 12month warranty - but I am hoping it will last more then 12 months!
Cheers

SubscriberMagneto Marelli is the new name for the Prince of Darkness (Lucas) to hide his true identity.
IMHO they are the weakest link in Land Rover products.
If you are talking an old RRC with V belts then a Bosch conversion is the best thing you can do as they are cheap , parts are available anywhere and they are more reliable, except for the regulator which is available anywhere and costs 50 bucks.

Once again I didn't read a post thoroughly enough and see 300Tdi Defender. Sorry but I do not know if a Bosch will fit.

I agree with Phillip A
My Disco is a 94 model. I replaced the Alternator 3 years ago.
The one I have now is heading the same way.
It does not like working in the cold mornings. So when I start up in the mornings there is no charge until the engine gets warm, then it is ok. In the summer time or on a warm day I don't have this problem.
I am told it is a faulty diode in the alternator and as time goes on it will get worse. Just like the last one.

To make up for my carelessness I found the above for you by searching.

Magneti Marelli have never had any connection to Lucas Industries, which In August 1996, merged with the American Varity Corporation to form LucasVarity plc.

Subscriberbefore you contradict someone on a forum you perhaps should do a little research.
It took me all of one minute.

My original Marelli alternator on my 93 RRC wore out the brushes finally last year. Absolutely no issues with it the whole time I had it apart from I cracked one of the legs after failing to put the crush tube back in once when I took it off to do the PS pump, and even then, it stayed there for a good 5 or so years that way.
The only reason i replaced it rather than repair is that i needed a bigger output.

SubscriberWell my 92 RRC 65 amp job died at about 85KK when the diodes died.
I was able to get a new board from UK and fitted myself, but I never trusted it from then on.
It seems the Poms never seemed to think that a Vogue would have aircon as they fitted a 65 amp to it but an 80 amp to the Vogue SE, when even a Magna had an 85 amp .
I fitted an 85 amp Bosch and it has gone well although the regulator died after about 100KK and I got new one at Repco Darwin for $50 and 5 minutes work."Have you got a Magna regulator?" "No but I have a Commodore one." "Let me see. That will do." Exactly the same.
Apparently the bearings last forever on Bosch , but the regulator /brush holder dies in some cases. I tried to get a second hand one but the workshop in Jabiru had 6 alternators in good nick but NO regulator/brush holders.
For me one of the big issues is ability to get parts in the bush and I carry the still working but intermittent regulator as a spare, since it only weighs a few ounces.
