Just don't... the basic stuff is the hardest because there's no proper logs or diagnostics,
Something like a euro mini would say something like
Fuse Failure 100 31/05/24 11:30,
Silenced by user 1 31/05/24 11:33
You then replace the fuse, note the landing sensor does not light up, look in the loft to find a rat has chewed the wire or whatever
Alarms are a massive pain the balls, don't get involved.... I regret getting involved
In the words of Zammo Maguire - Just say no...
