Alarm constantly on after new battery.

The vectra 150 sri is now finally back on the road, after all alarm and wiring issues. Mot passed on 30th March, drove 100 miles over Easter, running smoothly. Alarm is disconnected and no power sounder. Rewired some of car, so airbags and central locking works, all electrical issues solved. Cheers to KevinH for assistance last summer.
