On Sunday, I jumped in the car at about 2pm for the first run of the day, and it tried to start, turned over, then sounded like a flat battery, then nothing. Left it a couple of hours, and it started fine, first tuirn of the key.
I'ts been fine since then, until just now, bearing in mind I've been out in it twice already today, but it had the exact same symptoms as it did at the weekend.
I changed the alternator and replaced the battery about 18 months ago, but will it be the alternator again already?
I havent tested how much power its running because G's testy thing has broken, and haven't got round to taking it round for my dad to do.
