Hi,I had a new alternator fitted a couple of weeks ago.Since then the fuel ignition warning light is on all the time,and she is using a lot of petrol.The mechanic who fitted the alternator has looked but can't find out why,he took it too a diagnostic centre but they can't find the plug/socket thing to connect to.Apparantely it should be down by the hand brake but mine is blanked off.Does anyone know where it is on the cabriolet,please?
