to me thats a pretty normal alternator whine , yes depends on the generation but the diodes or whatever can give  a quite intense howl, whine  just like yours  ,,  

vee belts can give a squealing and sometimes a tin tappng squeaky racket but thats not what you have

there are aerosols of stuff like belt ease to dress the belt whithout loosing grip,  keep an eye out for its useful at odd times

talc powder will also quieten a noisy belt which is more suited to your cuboard.

great stuff to trace oil leaks  ,, dust the pwder and the leak will trace through and show its source...can smell nice too !!!

Quoted from JohnD
A dry bearing?  Do Rimmers expect it to wet itself?

Seems an unsatisfactory answer (I presume they supplied the alternator?) instead of an offer to replace.
Send it back?

John


I'll see how it goes and if it doesn't improve i'll get them to send another one.

Quoted from CyTry
My Spitfire (1980) whistles when I have the headlights on. Frequency varies with engine speed.  All belts etc. are tight, it's the alternator itself.  It's not annoying, sometimes I pretend it's a turbocharger...


Exactly like mine!

The alternator shouldn't whine, or screech. The noise you hear on modern cars is either the power steering pump (Mini's) or cam belt. The one in my Herald makes it sound like a mini-supercharger. Honest.

Look down the line of all the pulleys. Are they perfectly aligned? A possibility for noise is that the alternator pulley isn't perfectly in line with the other two and you're hearing it run on the outside edge of the belt which will slip compared to running on both of its outer sides. Feel free to hold a straight edge up against the pulleys to assist your eyes. My money is on this being the issue.

If all is fine then stick a long screwdriver on your water pump and the other end on your ear when running and see if it sounds like it's coming from there. Drop the belt off and spin the pulleys on both the water pump and alternator and do so again whilst putting load on them. You're looking for anything which doesn't feel constantly smooth. I'm saying this as before everything may have been "loose" and if you've now got everything correct it may be showing up weaknesses on things like the water pump.


Release agents on the belt should have been worn off by now si if it's none of the above... your alternator is buggered. Possibly.


Acclaim - fully working and on the road
13/60 Herald - mx5 powered and other such fun things, legal enough...
Mk1 2000 - it's still alive, just sleeping
Expert 815d - the slug

If in doubt, do up until you hear the crack and then go another 1/4 turn to ensure tightness.

The kit has a lucas 17ACR unit  it will whine and sing  they all do and always did in their heyday
its a normal characteristics of the vintage

from your video I would be more interested in the tappet noise  you can improve that

gaps are 0.010" cold engine   how to details in your manual

Had an interesting one today.
I drove to my Dads in Hertfordshire about 80 miles. When i got there i turned the engine off for about 5 mins and it refused to start again. Turning over and not firing at all.
We went for lunch and i tried again over an hour later and still no joy. I left it another 5 mins and tried again and it eventually started.
I drove it to the petrol station and filled it up . It only took 16 litres.
It was then fine.
I drove it all the way home, which was probably less miles but more time in traffic.
When i got home i tried turning it off and on again after various gaps and it's fine.
I did stop and Mooredale Motors and spoke to Dale. Who said he'd have to book it in.
Bloody thing.
I meant to show him the Alternator but i forgot.

Might be fuel vaporisation.   Heat radiated or conducted from exhaust manifold cause fuel I supply lines and or float chambers to boil.   Doesn't happen on the move as airflow helps cooling.

A heat barrier between them can help, a sheet of alloy between the carbs and manifold, wide enough to screen the floats.  And make sure the supply inevruns around thgthge front of the engine, preferably not touching the block.

That's interesting. Like a bit of aluminium?
