Looking though old posts Ive managed to locate, remove and dismantle my alarm siren which is not working. Just wanted to ask before I start trying to repair it wether it is worth the hassle. Aparently these alarms are about as much use as a chocolate ashtray even when fully functional. Is that true, and if so is there a replacement uprated alarm avaliabe that plugs straight in (or near enough) or do I have to get an aftermarket one? Thanks in advance.
