I am having issues with my Flashpoint alarm. (along with a few other wiring issues).
They go somthing like this...
When I shut the car down and the turbo timer kicks in after a few seconds I get a noise like a phone ringing through the front right speaker, this is interfearance similar to what you get in a poorly wired car audio install where you can hear the indicators clicking through the speakers and hear the engine revs rise and fall through the speakers. but the source is from the alarm I will describe it as a house phone ringing.
Secondly in the morning when it is cold I start the car and drive, for the first few miniutes the battery isn't charging (looking at voltmeter) and is reading about 10.5-11.5 volts (read not good). things like power windows, mirrors, blower fan don't operate. As the car warms up the meter jumps to 13.5 (or so volts and phone ringing goes away and all is good. I am however yet to see the voltmeter read over 14 volts.
Now... The flaspoint alarm I have came with the car so I don't have instruction manuals and the like but I was given a pager thing that is supposed to alert you from "up to a km away" if this is the case I would assume that when the battery drops below a certain voltage the alarm pages you to tell you there is somthing wrong. My guess is the phone ringing sound is the alarm emitting the signal to the pager (yet to test this theory)
In my case I think the battery is p00 failing that the alternator is p00.
Cool1 before you jump in yes there were some earth issue which I checked and reconnected (yet to look at the starter moter earth But there is a problem there) along with some shorts that keep shutting down the stereo H/U. but I'm pretty sure the battery has carked it and I will be replacing it on the weekend to see if the battery charges. if not I'll be looking at the charging system.
Papercut I'd be checking the battery first for charge.
