SierraYankee99 Posted April 25, 2009 Share Posted April 25, 2009 Possibly a bad earth from the alternator or could be a faulty alternator you've put on. Other than that, could be the fault codes not been cleared from the ECU and the car still thinks theres a problem. Quote Link to comment Share on other sites More sharing options...

If the lights on the alternator wont be charging the battery. So it will be a bad earth somewhere, the aux drive belts not tensioned properly or a faulty alternator still. If the aux drive belt is the same on the petrol as on the diesel the belt doesnt come into contact with the alternator pulley much at all. I'd prefer to see it going 180 degrees around the pulley but mines 90 at most, I presume the petrols the same so a properly tensioned belt is essential.
