Right you are. And I'm mistaken, I was measuring ohms when ignition off and volts when ignition was on.
That's fine :D

I shoudn't bother trying to measure milliohms - I think you've done enough to ensure there are good earth connections.

Personally I wouldn't bother trying to fix the alternator when...

is available for a few quid more and means less work for you.

Demonstrated to me by 2CV specialist Nick Cordiner a while back. Just shakes loose some of the crud and allows the brush and slip ring to make contact again for a little while. Put off the evil day of changing the alt on the grey one by about six months!

I got slip rings and brushes for my original fitment Valeo alternators from:

An update.

Was a few issues. But quite straight forward in the end.

- I never really questioned the integrity of the 2 year old Bosch battery. However, it was a goner, only holding 30% capacity. Of course having trouble getting it replaced on Bosch's 3 year warranty. Bought another one and will try to swindle something in the future ;)
- The valeo alternator I'd got on ebay, just my luck, was working fine when I fitted it, and continued for the 1st year or so. But clearly it's brushes/regulator are gubbed. I bought a replacement regulator housing and slip ring yesterday from a nice autoelectric shop here in Glasgow. Prolek is the place, I recommend them for friendly advice and good prices.

Will get the Alt reconditioned and new battery in and fingers crossed, all will be well :)

I hope all the other fiddling about, cleaning wiring connections and earth contact will reduce the chance of something else going wrong in the future.

Thanks for all advice. ;)

Glad you're getting there! I've had problems with Bosch batteries in the past, failing well before they should. Might just have been unlucky, but I prefer to avoid them now. Had good experience of Varta batteries from www.tayna.co.uk
