I have had issues on a few vans were after fitting after- market alternators for customersthey have caused issues. I now only fit Ford ones.If the alternator is installed and rated correctly for that van then it maybe the part itself. Do know why the original alternator was replaced.

It stopped charging van Regards Anne do you know why it would affect Abs? as soon as you try to put your foot down it flashes up on dash service now goes into limp mode then acts normal and then you read codes and the dam code will not erase

Is the abs light on ? The code will most likely be set due to improper shut down due to low or incorrect voltage. Am i right in saying that you had no issues other than a charging concern before the alternator was replaced?

Are any other codes present, have you checked all related abs fuses.

Hi no other codes and yes the van died due to no power from alternator everything else touch wood is working as normal, i used forscan to try and clear codes but it either doesnt do it or fault recurs, and there are no lights on just when you accelerate Regards Anne
