andy2986 Posted December 1, 2020 Share Posted December 1, 2020 Hi all. I’m wondering if anyone can help me. I am getting very close to finishing my disco rebuild project. Am having a few ‘mopping up’ problems. The whole alarm/central locking/immobiliser system has had me going for a while now. Ive had the green box and two remotes rebuilt (re-synced?) and is now working as it should but now the sounder isn’t working correctly. If I activate the alarm you can hear the sounder trying to work but very very quietly ! ive bought another from eBay but it is rubbish and makes no sound at all. so, is there a way of fitting a different alarm sounder ? The original is proving tricky to replace now. or if anyone has a working alarm sounder they want to sell ? oh it’s on a 97 300tdi discovery cheers andy Quote Link to comment Share on other sites More sharing options...

All very straight forward Edited December 5, 2020 by teabag Quote Link to comment Share on other sites More sharing options...

teabag Posted December 6, 2020 Share Posted December 6, 2020 When we moved on from burglar alarms with a bell we used this type of sounder, as a money making upgraded.😀 Still available on eBay. Quote Link to comment Share on other sites More sharing options...
