Hi,

I have a 92' 300ce (W124, 119,000 miles, all original parts except battery), with an alarm problem. One day I manually turned off my stereo then turned off the car and then the stereo turned back on with the cassette reels just rolling and heating up to the point that I saw smoke. Ever since then I have had problems with my alarm. Now my alarm just turns on while I am driving or even when I open my doors at random. Now I have cut the two brown wires coming from a little chip from inside the siren to the actual siren itself. Then I disconnected the ground cable and then my battery. Now I hope tomarow morning it will all work.

I have been reading and it seems the best thing to do is disable the alarm modulator. I do not know what it looks like or how to disable it. I do know its under passenger carpet though.

Can anyone help me fix this, by either turning off this modulator(if it solves the problem ) or any other suggestions.


SORRY FOR THE LONG POST.
Thanks for any input
