1990 3.9 RRC

Moved it a moment ago and the rev counter failed to operate.  This
sometimes happens on both of my RR but usually it springs into a life
after a few moments.  Not this time and when I turned the engine off the
battery charge light stayed on.  Also, strangely, so did the ventilation
fan for a short while.

Any thoughts?

If it's the alternator I have what is rapidly beoming a donor 1989 3.5
RRC on the drive!  Would the alternator out of that fit?

TIA

It'll be the alternator. If the 3.9 is an SE and the 3.5 isn't then the
alternator will work but you should really put the more manly one on. If
it's the other way round, no worries :)

Thanks Pete.

Both are SE spec.

Out into the - inevitably in situations such as this - gathering gloom
and falling temperatures I go  ;-)

Check the connections off the back of the alternator. Sounds like a
dirty/loose one.

Hi Dougal

Duly swopped!

No more red lights with engine off. I'm not sure if it was clear from my
orginal post that the warning light only illuminated with the engine off.

And rev counter now works.

But, judging from how tight everything was, it _probably_ wasn't a loose
connector (I hope).

I'll get it checked anyway.

I'm pretty sure you'll have sorted it. I had the exact same thing happen to
me about 10 years ago. On Boxing night, miles from home...

Last time an alternator failed I was on my way to my cousin's funeral  :-(

As it happens, it is the very same one that I have removed from the 3.5
RRC to the 3.9 RRC today.

I had an alternator go short-circuit and start to incinerate the wiring.
Luckily, I had the motor in the yard with the bonnet up at the time and was
thus able to disconnect the battery pronto, but it had the potential to go
on fire.  The output cable of the alternator is usually pretty fat, and
takes a lot of melting.

chances are it'll be a regulator fault.  depending on where you are, you may
find someone who can fix it, e.g. by replacing the regulator.

Dropped it into Curd Brothers, Tunbridge Wells on Tuesday, picked it up
Wednesday lunchtime with new diode pack and pair of bearings.  £47.50.
Load tested as giving 70A @13.5V

Interesting to note that with the alternator from my 1989 3.5 RRC, the
O/S heated door mirror now works.  Neither heated door mirror has worked
on the current (3.9) RR in the year that I have owned it - I swopped
both mirrors from the 3.5 RR because I wanted the convex mirrors.  The
HRW did, and still does, work.
