Thanks for quick reply garage has had it for 2 days and fault not showing now. Got to drive it 100 miles next week and don’t want it breaking down. Was hoping just an alternator change but garage said it tested ok. Don’t know what the reading was. Hope it’s not one of those intermittent faults that are hard to diagnose.
