Hi people

Could do with some help and advice on alarm fault.
When the alarm is set off the indicators flash but no sound from siren, have tried checking all visible fuses with no bad fuse, and tried a used other siren but still no sound from other siren so some guidance for

What to measure at siren when it is activated and de-activated

where is the siren fuse exactly so I can check voltage there

and basically anything else to check

I have tried measureing at the siren plug and do have a 12v and an earth on the 2 outer wires no idea what to check on centre wire of plug

Thanks

You're most likely find the answer in this thread

Thanks Argo did have a previous read ..as i have a 12v feed and earth I think maybe it is the centre of the 3 wires that must be the trigger wire for the siren and maybe my problem, is there by any chance a wiring diagram anywhere for the alarm circuit can not find it on any search or would this elearn be of any help..suppose another option could be the second hand siren I got is duff but just trying to make sure the siren is getting the correct signals first..

Thanks again

Yep, all the info in that thread came from eLearn (see FAQ section).
