V8 Alternator problem

I have the following symptoms on a 1984 3.5 V8 90:

Charge light comes on as normal before starting engine, When I start the
engine it goes dim but as you rev the engine it gets brighter. According to
the bible it is the main output diode that has gone open circuit. Is this
something that

1. I can do anything about (without complete new Alternator)
2. My normal landrover garage can deal with

or do i need a specialist auto-electrician to refurb the alternator.

also why does my alternator not look like any of the ones in the manual

Any advice is appreciated

Rob

What does the alternator look like? Is it not a Lucas one? Any numbers etc
on it?

Quite likely, assuming parts are available.

Yes, if they are competent and not just "change the broken bit monkeys".

Might be best solution, at least they know what they are doing and generally
give some sort of warranty on their work.

'Cos it's been replaced at some time??

If the Alternator is getting a bit old, a complete recon is probably worth
it for piece of mind. i had a large diesel alternator completely reconned
about six months ago (cost a little over $200 AUS) and it came back looking
brand new. i reckon you'll probably save in the long run if you get the
whole thing done at once. Just my thoughts anyway, and i dont know what your
alternator wil cost but i can't imagine it will be all that much more.

Cheers.
