Hi Folks,

I have a Porsche n/a 2.7L 1989 that has suddenly discovered electrical gremlins. It is fitted with a Cobra Alarm that has a fob that turns off the immobiliser so the car can be started in the next 30 second period. If the immobiliser is not dis-armed, I believe it stops the ignition circuit from operating, but it may cut power to the DME relay as well, I just don't know. I had some battery problems and had to jump start it from a spare battery this morning, but it stopped at work, and will not now restart. I have replaced and recharged the battery, I have plenty of volts now. Well, at the battery anyway.

Although the immobiliser appears to be turned off with the alarm fob normally, (a red led goes out), the ignition lights no longer light up when the ignition key is operated, so there is no action. When the ignition key is operated a few times, sometimes, randomly, the red led comes back on as if the immobiliser has decided to re-arm. So the immobiliser has at least something to do with the system both before and after the ignition switch. The red led sometimes dims as well which is a bad sign as if there is a poor connection to the immobiliser.

If I want to get round this problem does anyone know anything about this Cobra system? Like where it is, and what it hooks into and defeats!!! Or any relays it operates?

The electrical diagrams for the 944 in Pelican have some of the ignition switch current tracks missing on the page boundarys, can anyone fill me in on the complete circuits, please, maybe pm me perhaps?

I need to know what I can jumper out so I can get the car out of the car park at work..!

best regards
Russell
