Hello all

1998 C2 996 Carrera

For the last month I have had voltage drop in the battery. Abs, traction and battery lights come on. Electrical systems (radio, wipers indicators) slow down. If I keep driving the car eventually stops (eg 10-20 miles) and the battery is dead.

The alternator has been replaced twice. The battery is brand new Porsche. It is still doing it. I am at a loss.

Any ideas?

Take a look at the electrical section here if you've not already done so. You might get some ideas.
