Battery in the Astra died. I took it out and charged it, however when I reconnect it both the alarm and the power sounder go off. I cannot seem to stop them - even when I turn the engine on they still sound.
Have tried searching, but can't find how to fix it. Does anyone know how to reconnect the battery, without alarms going off?! (MK 4 2.2 SRi Hatch, if it matters!)
