Laserline 975S - need help with resetting after new car battery
I have a 1984 944 Porsche which is fitted with a 975S Laserline alarm/immobiliser/central locking system.
Two days ago I replaced the car's battery, and since then I have been unable to start the car. The car will turn over, but will not fire. There is no spark from the coil, and I think that when I disconnected the battery it has somehow locked the imobiliser system.
The central locking, which is all part of the alarm/imobiliser remote, still works fine. I am able to open the car with the remote, deactivate the alarm, but the car will not fire at all.
I have looked at several Laserline websites, but have not found any information on this particular alarm/imobiliser system.
I am wondering if anybody has any information about how to reset this alarm/imobiliser, or how I can find out how to do this.
Really appreciate any advice at all.
