Sorry i wasnt clear there. I fitted a 70amp one to it a few months ago but the gti i have has the air con which was fitted with the 90amp as standard. I wasnt sure if this would take its toll on the 70 amp one i fitted?
Engine man light has been on since before fitting but battery light came on 2 months later. I couldnt find out what the engine man light was on for as the diagnostic machine couldnt read it for some reason so there may be another reason for that.
If a 70A alternator was fit onto a Lupo gti instead of a 90A would this cause problems? The battery light on the car has come on could this be the problem? Any help on this would be appreciated. Cheers Gary
