Re: Selespeed sticking me in Neutral at roundabouts!
35 sure aint large these days. There are dangers in buying a much higher capacity batteries 1) to your WALLET and 2) it'll be physically bigger and probably won't fit! Obviously I appreciate you wouldn't buy a battery if it didn't fit. If the battery on the car is not the one specified, by a fair margin, then get one that is. After that I'd be sitting on the edge of my drivers seat waiting for my instincts to be proved right and the problem to return! If you have the right battery and it's in good condition, it is not the problem. A battery 'drop-test' costs little or nothing. Just a question of finding a man who can. Tyre/Exh/Batt shops will be able to (but have something of a vested interest in the result).
By the way, what you need on your battery terminals/clamps is cleanliness, apply nothing except possibly a wipe withclean rag and wire-wool untill the thing is done up, and don't overtighten. As has been mentioned, it's worth making sure that connections that come off the battery clamp or nearby - and especially earth points on body and engine are all properly clean and tight. Once they are, a bit of vaseline does no harm, but only after all else is cleaned and back together.
Sorry, this has turned into a bit of a preach.
Doesn't say that in the manual
