Really quiet car alarm noise
« on: 20 June 2012, 10:39:10 »

Hi, Wonder if anybody can help me.  My Omega has been off the road for a couple of months (son at learning to drive stage so had to buy something mini for him to learn on - Sorned my Omega with a view to getting back into it once he'd passed test but now realise that it's impossible to insure him on it so will need to keep the roller skate and get rid of my proper car - boo!).

Any way, less of the rambling.  Charged the battery and she started first time but every time i turn the ignition off there's a really quiet car alarm type noise coming from the engine bay - I've seen this in a previous thread .......

"The only "alarm" near the reservoir is the power sounder I believe. Are you sure the sounder is ok and it`s not the alarm horn that works ok :question"

and that thread suggested opening it to rplace the battery or disconnecting it?

....... please can somebody clarify what the power sounder is (I assume that this is what is making the noise) - can I mend it etc?

Many Thanks - Neal

Power sounder is a back-up to alarm if evil people disconnect car battery-- general concensus on here is that power sounder is recommended to either take-out (preferable) or replace- as they have a habit of spontaneously combusting and making the car approach 600 deg C on average!

Many Thanks Kev - I've found the guide so will have a bash at disconnecting - it's really quiet though - I can't imagine it scaring off those evil people - possibly it's on it's way out? ...... I'll get it out before the whole thing combusts!

Cheers - Neal

If it is REALLY quiet .. it is possibly very low on power if the batteries are past their best.. it will therefore attempt to recharge .. if the board is corroded this MAY cause an overheat and fire ... :(

IMHO remove ASAP it only takes 10 minutes. Then replace with a new one for £40 ish  :)

Get the bloomin' powersounder out and thrown away.
That's how mine started, with a very low note, then went off like a ships' horn.
Woke half the neighbourhood up.
