*Update*
Spent the day yesterday sussing why the alarm didn't seem to be working on the Black omega.
Discovered yesterday the alarm horn connector contacts were seriously corroded from water getting in, at first i wasn't sure the horn worked so i plugged it into the loom on my car near the power sounder and tested made a nice racket.
Cleaned the contacts on the Black omega alarm horn connector and plugged in the horn and tested all working but I think I need to replace the sensors as one has been hit and the clips that hold it in place are not the best.
Originally you could just sit in the car and nothing would happen, first sign the alarm was functioning before the actual horn worked was you could hear the relay clicking from inside the car.
Now the sensors work and the horn sounds when the sensors are activated.
Not bothered about the indicators part so long as the alarm works.
Having discovered mine only has the powersounder not sure if it should have both so any confirmation would be much appreciated.
Cheers
