Car Forum / Porsche / Porshe 944 / February 2005Removing S2 alarm system
Hi All, I've had to get an alarm fitted on my UK '90 S2 to keep the insurance company happy and now need to disconnect the factory fitted alarm that came installed on it (I think it has problems anyway), is there anything special I need to do as I'm guessing that I can't simply unplug the device as this would immobilse the engine. Regards Derek > Hi All, > [quoted text clipped - 7 lines] > > Derek My insurance company insisted on an immobiliser - in addition to the factory fitted imm and alarm. I now have two imms and an alarm - works fine in combination. Not sure about two alarms, though - did the company who fitted alarm two not advise you? > My insurance company insisted on an immobiliser - in addition to the > factory fitted imm and alarm.

The company who fitted my second alarm were supposed to disconnect the original one (needs doing to fulfil the thatcham approval) but they didn't touch it, they did however remove the second immobiliser that was on the car. I had a few issues with the alarm when I first bought the car (not disarming from passenger side) so I thought then when the new alarm was fitted and the old disconnected the problem would go away, the problem isn't as bad now as I now have remote central locking. but I have a problem with the battery loosing charge over night and am currently trying to locate the culprit and thought I'd disconnect the alarm first to see if it's that.

Your Insurance company presumably directed you to them, having selected them from their panel of approved fitters - hence the insurance company will be interested if they aren't up to scratch. There is a fault that can develop on the factory fitted alarm, that happened on my '89 944. The alarm is fitted with a small back-up battery so it can still raise the alarm if the main car battery is dead. This is trickle-charged whilst the engine is running. However, the fault causes it to charge all the time, even when the ignition is off, resulting in a dead car battery. Having the alarm enabled or disabled whilst the car is parked makes no difference: the back-up battery continues to trickle- charge regardless. The solution seems to be to disconnect the trickle- charger/back-up battery on the alarm (there must be a better fix!). This approach certainly seemed to fix the problem for me when it happened.

One is an alarm, which is disabled by the remote. The other is an immobiliser which is disabled via a special key inserted into the steering column. |
