Alarm sounding when I disconnect 12V battery!
2016 Zoe. Have had numerous warning lights come on. Figured it was teh 12V battery which was reading 12.1V. Disconnected the -ve terminal, all good, disconnected the +ve and the loudest alarm ever went off, only way to stop it was to connect both terminals back up. Anyone else had this? Was I doing something unsafe - e.g the main battery was still 'live'.
