Hi guys recently bought a fabia vrs after a while the batter stopped charging tested it and was only showing 9v and decreasing while engine was on first instinct was to replace alternator which has been done but did not fix the problem ? Also along with this I've replace the entire loom but still nothing dunno what else to try ??? Please help

Are you sure this is a Fabia 2?

If not more than likely the DFM wife had broken in front of the gearbox. Pretty well covered if you search.
