Alternator

[HarryW]

The alternator light came on last night on the way back from the Hants meet, so I was forced to drive back on side lights to try and preserve the dieing battery voltage level .
I know some of you would say that there's no difference between side lights on dipped beam on an S, which I won't disagree with , I'd just like to have full volatge available to me so I can use full beam if I want to .
I've read up on griffs and chims and have heard of a fuse link to do with the alternator, but try as I might I can't see it. Anyone know where this would be roughly sited on a V8S .
Just to make sure I'm not barking up the wrong tree I measured the voltage on the stud on the back of the alternator and its battery level at all times, i.e. doesn't go up when engine is running is this indicative of a shagged alternator or is it the mystery fuse link any tips gratefuly recieved.

Shnozz

But do you know if your your ignition is on and engine is actually running? Now that you can't hear it!

You mean he could hear the S? I couldn't..

It sounds like the alternator may well be duff.

Does the ignition light stay on with the ignition switched off ? If so then it points to a blown diode pack. These can be sorted by a auto electrics company.

I would not expect there to be a fuse in the alternator circuit, but I could be wrong, and it is a TVR after all.

[HarryW]

I have a feeling you're right, I've checked it out tonight and there definately is nothing between the alt and the battery in way of fuses. The wires meet at the starter motor. Yet more bl**dy bills..................., need to find a local man that'll re-build it for asmall fee, failing that anyone know the Lucas part number for the diode pack it houses the brushes as well, I think.

OK then, anyone just changed the regulator assembly before on one of these, I assume its a rangie sourced part if so I think its RTC5670 (on rimmer bros) anyone care to add weight to my guess :confusd:.

Harry

Edited to ad I think that its a Lucas A127 alt which I think was standard for pre serp engines without air con, anyone care to .........................

You don`t seem to be having much luck with V8S at the moment H did you get back o.k? were you in convoy with someone? I might have come across the part you were looking for at the Beaulie auto jumble today nearly 2000 stalls 8hours and still didn`t see it all! Give me a shout if i can help TONY

[HarryW]

Cheers for the offer Tony, but I think I'll change the whole lump now, I've been looking into it today. Not sure if its the regulator or the rectifier thats gone, either way the things been in the car for 9 years and it all looks a bit tired now, rotor / stator etc so its just as easy to change it all rather than change another bit of it in 6 months time .
For those remotley interested, it would apear that its a Lucas LRA 463 type, lucas part number 24161, a repacement would be a A127 65A (Right Hand) one which Rimmer Bros seem to do for £96, part number RTC 5680E.
Note if you have left hand fixing there is a different number. I'll double check my local man can't get it cheaper than rimers before ordering. Either way worth adding the number to the S parts guide for future reference.
Obviously AIMHO as per..................

Sorry im a bit late to this thread

Yours look like this (mine), might need one myself but i'm going to check out some carpy wiring first

[HarryW]

Looks the same to me but check the labels on the the actual alternator, see this pic [pic]www.lucaselektrik.com.tr/picture/alternator/24145.jpg|[/pic]
More details to check through if you want to on the Lucas site, worth adding to the favorites for any lucas bits www.lucaselektrik.com.tr/

Ahhhh well fitted it last night, all is now OK in the V8S world, have forgiven the car .
Part number posted below is spot on , the only difficulty is getting the pulley off the old one. By f**k it is on tight, I ended up jamming the spanner into a corner of the garage to brace it whilst turning the pulley allen key with a 3 foot extension, even then nearly had a hernia doing it .
Got the bit from my 'local' garage man via the part co. £86 all in .

Good glad all is wellprobably next on my list

Im expecting a upgraded fan tommorrow i'll let you know how i get on with that

Its same size but much more efficient and powerfull, supposed to be quieter but i doub't i'll notice

Talking about 'upgrades' whilst changing the pulley over between alternators it reminded me when the belt came off recently I promised myself one of those serp type belt conversions that V8Developments do. Where you change all the pulleys and fit a proper V belt to the pre-serp cars. Apparently about £150 for the bits and a bit of your finest labour, a job for later in the year now as I can't face taking three pulleys off after struggling with the one this time , perhaps I get the bits and get it done next service.
BTW the part no was the last one I gave for the Lucas bits, it can be obtained just on the 24161 No,. but make sure that you state RH fitting, not that it shouldn't be though on that part No.

Sorry to hijack your thread Harry.

Pies, what fan are you upgrading to, mine is OK apart from it is sometimes hard to hear the wonderful engine note over the sound of the fan!!!

I've been thinking about an upgrade to a Kenlowe but I'd be intereted to know what you've gone for.

Colin

[pies]

Going to try one of these

www.merlinmotorsport.co.uk/catalogue/fans.htm

If its no good i'll let you know.....come to think of it i'll let you know anyway

[HarryW]

I take it you mean the tripac one and not the davis craig one
Blimey, the blades on it loook very much like the ones off a submarine , very efficient, quiet, no cavitation, shite at going backwards, perhaps they've studied some photographs and copied one .
Let us know, as you said, either way.

harry

[pies]

Yep tripac,well somebody has to try these thigs out

After all our fan design must be at least 10 years old and the fan itself could be 10 years old

[HarryW]

I doubt very much if the design is only ten years old , but then again its probably no different than 90% of cars out there you could buy today.
