My viper 480xv has decided to play up.

I know its an old system.

I found the battery backup has died on it, and now everytime i power up the car

(i leave it with battery off in garage as not used that often) the siren goes off.

The immobiliser still works ok but the alarm siren part is faulty.

I have tried everything

(im an electrician) and it looks like the main ecu is sending voltage to power the siren when not needed.

Anyway.

.back on topic.

So does anyone have any recommendations on what alarm to get fitted.

Ideally i will get rid of the viper and have the new system installed to replace.

The viper is thatcham approved

(i here there is no such thing now?).

Im not too worried about this now as i could get a seperate immobiliser fitted for next to nothing however it would be nice to have an all singing all dancing.

Im in wiltshire so if im not fitting myself i need someone to be local or mobile to fit.

What suggestions have we got?
