A little direction for the mechanically challenged. As stated, clean all connections, power and ground. Measure DC at starter, both pos. and neg. Now, I've done a lot of cars and it's usually the started solinoid. It is a magnetic/ DC coil that pushes of pulls, depending on the car, a copper contact that conects the battery terminal to the started motor. A click is ussually a worn contact of bad solinoid. It's trying to make contact but is not. A tap on the side usually gets it working a couple times if your stuck somewere but needs immediat repair. In American cars the starter dis cheap and copper contact plates are $1. Never done a Porsche starter though. Take it out and take it to a local shop. Don't go to the local Autozone or such thing. They can test it hole but have no idea what causes the fault. Look up starter or generator in the yellow pages. They always test them for free for me. Most also carry Bosche parts.
