I said on an earlier post:
I did notice that there's a fair amount of corrosion on the connections that the wiring fits into on the plastic module which goes onto the positive battery terminal, so I'm thinking it's probably a good idea to clean all those up to make sure the connections are all good before I start buying parts that may not need replacing
Never did do it as I couldn't get it off, just mentioned it to the lads round at the garage before I went away for my holiday
They replaced it with one they picked up at a breakers for a tenner and it seems to have been going fine ever since ... they were good enough to use up half the petrol I'd left in there using the car for trips to the chip shop, picking up parts they needed etc
And they smoked the pack of cigs I'd left in there!
That's surely sorted it though as I've taken it for a forty mile drive myself since and it's now running as well as it was before all this started, maybe even a little better
Thanks to all those who tried helping me and made suggestions
