Topic has been done to death, but it gives me something to post...

A job I intended to do last year whilst I was replacing all my fuel lines, but couldn't because most places closed as we went into Lockdown 1.0.

No alternator issues noted, but it is 33 years old this year.

Start point:

Some heat damage to the positive cable.

Alternator and fan/housing out of the car:

Alternator removed from housing and using puller to remove the fan:

33 years of use...

Alternator shipped off to Electrostart in Daventry and returned a week later....

Really pleased with the service. Apparently the alternator fell apart when it was removed from the casing. So perhaps a 'stitch in time'.

Shiny!

I am awaiting the return of the fan and housing from Greatworth Classics.

£189.71 - includes the return postage to me but not the postage cost to get it to them.

Sounds about right. If you look closely at the pics I don't think that is your original unit refurbed, just a straight exchange. Doesn't matter though as long as it works.

Phil I don't believe so.

They sent back the bag of 'knackered' bits.

Get some heat shrink on that red wire!

Indeed - have ordered some very high temp tape.

My first thought was to replace it all but I'll go with some temp resistant tape.

Hi Chris,

What are the plans for the fan and housing, original, or adding a splash of colour?

Hi Kevin

Fan & housing are at Greatworth Classics being refurbed so the finish will be largely 'original'.

Should look very similar, accepting of course the superior 3.2 engine it will be fitted to....

Bit of time on the car this afternoon, not all good news...

It was clear when I removed the alternator that the main live cable was not in good shape - there was clear heat damage to the insulation. So, rather like pulling at a thread I started stripping it back. I was hoping to get to point where I could see that the insulation was good but...

Wiring-1.jpg.71e81d38a50f797229ef4da8d035d775.jpg Wiring-2.jpg.e200d1107e95766844cd44adc8b92a3e.jpg

Wiring-3.jpg.0504fefaab58ac4aadd0c6d52179c76e.jpg

Wiring-4.jpg.38cd5852171c91bf819f2921eae65da6.jpg

Short story is that the insulation at the point I've got to still isn't good.

So I really need to replace the wiring.

Does anyone know if a replacement wiring loom is available, and from whom?

Doesn't that main feed only go to the starter so should be relatively easy to replace that cable only?

I believe so Roy. I think the smaller red wires go to the engine fuse panel.

Was hoping to maintain an OE look but I guess I should take a simpler option now and when (if!) I ever drop the engine look at replacing more of the engine loom.

I've made a couple of looms parts myself, get decent quality high spec flex off t'tinterweb same colour, etc then sit down with your soldering iron, connectors, heat shrink and match what you've just remove from the car.  You'll save £100s than buying the OEM part.

Yeah - I know you're right Nige.

Feeling lazy...

Think the part you need is 91160701602 main engine loom, I could be wrong.  Assuming its not NLA I think the price will soon make you feel rather less lazy!

Indeed!

I think I'll replace the live cable for now and think about a more involved loom replacement when (if!!) I drop the engine.

Euro420 here:

Just rebuild it yourself and wrap with loom tape.

 

If you don’t want to make the replacement main cable, I have an original thick red wire, removed when I fitted a Classic Retrofit hi-power alternator.

If you want to go this way, just cover the postage, Chris.
