    check your earths

    a multimeter will show a bad alternator, measure voltage before starting and then start car, the voltage at the batt should go up to around 14 ish volts. If it does the alternator is 99% working fine.

    Check volts at the batt, however IMHO there is no way for alt output to have a bearing on this at all. It will more likely be an earth in the car, probably under the knee bolster or similar

    Agree with you chief! The dodgy earth could be under the steering wheel trim

    It's a process of elimination with electrics, when you put any heating device on your asking for alot of voltage, is the car actually going off when you put the heating on full?

    well the first time it done this was when i was driving along the motorway and i pulled over and turnded the engine of and it wouldnt start again it was like a had a flat battery. but to answer your question whilst just the engine is running and the heating fully up the engine is not cutting out now just the dash goin and also the interior light flickering.

    I'm not sure which earth it'll be you need to check, just to be on the safe side, just check if your earth on the battery is secure and not loose, could be an easy fix

    FFS just get it tested, KWik fit will do it for free, it could be the voltage regulator within the alternator. There's no point in hunting for a bad earth that might not even be there, it could even be a dry cell in the battery
