Hello My wife has a 55 plate C3 sensomatic that has had some bad running and occasional stalling, the previous owner took it to a Citroen garage that said the stop start auto alternator connections were corroded and may need a new one, a year or so later i decided to clean the terminals on the alternator and now it will not do anything!! I didn't know about the battery disconnect procedure and also lost windows radio etc! I have rebooted the BSI and have everything back but will still not spin over the alternator to start, fault code reader says P1390 auto reverse alternator position sensor. Have I buggered the alternator by just disconnecting the terminals and cleaning them? Regards Colin
