Alternator options

I've not seen any mention of the alternator warning light in the dash, does this come on with the ignition and extinguish when the engine has started?

Nothing coming up no. I'm having to charge the battery to start the car and it's getting worse. It could go 3 weeks now ill be lucky to get a week

If you've any doubts about the performance of the alternator, it sounds like you need the alternator equivalent of Darwen Diesels for injectors - does anyone have any recommendations of a place to get an alt refurbed properly at a good price? @depronman ?

And a good suggestion for a tool for the tensioner :)

A three leg oil filter wrench can be used to manouver the tensioner, but even better if the legs are shortened a bit (not done in the picture)

Dead cell in the battery will bring down the voltage and ability to charge.

Is the battery sealed? If not check to see if a cell is bubbling gas or if dry.

Trickle charge/ slow charge is working fine so if I'm honest I'm thinking the battery seems to be ok from what I can see. Battery is getting to 13v when the charger shuts down and it taking a number of hours to get to the point.

Ribbledale auto electrics I. Preston are very good, not local to you but a very long established co who always do a cracking job

It must be alternator failing time on the A2 tdi’s as I had to replace mine on Saturday
Luckily A2steve had one for me as I only needed the 120amp alternator
I had been having starting issues for a few months but as the A2 is not used as much as when I wasn’t working from home and still on its original battery (21 years surely can’t be the end for the battery ) but battery took a charge off the car and held the charge perfectly over a week plus I had it drop tested and it was perfectly good
Finally the battery light lite up and would not go out, multi meter confirmed no charge
Changed alternator and 14.7v at the battery on tickover. Does not increase when rev’d up but it may drop back a bit once the alternator as fully charged the battery’s
I will be investigating the failure on the old alternator but it really wasn’t worth me b****ring about with it when Steve sent me a replacement for £27 delivered

I’m sure ribbledale auto electrics will post your one out if you ask but there may well be a more local co to you that does an equally good job

New regulator/brush unit? You can easily fit it yourself. Make sure that it matches the original output (found from the codes in the service book).

Ok so I don't have the time at the moment to invest in fixing so purchased another refurbished unit from a long standing company for under £100

I don't though have you send back the old unit so I do have the opportunity to fix and keep in reserve.

What parts do I need for 140a brush and regulator replacement anyone know?

I do get this but I'm not clear on differentiation between any of the regulators that autodoc sell aside from brand names. What is a known good name for car auto electrics?
 
I'm struggling with a 3/8 torque wrench and socket to get enough space to pull into the correct position to put in the pin. I'm likely about < 1cm short.

I'm attempting from the top rather than the bottom.

I know I've asked above but could do with off the shelf cheap solution to allow me to pull the tension back enough to put the pin in to keep in place. I removed the water drain but I'm now hitting the plastic intake just in front of the metal frame and this cant be removed as one of the screwheads has rusted to oblivion. Thanks!

Any chance of a photo to show us exactly what you're up against?
 
Yup here you go. I'm pulling the bar towards me but I'm only just running out of room to align the holes to push the pin in.
